We Need To Talk About The Pale King's Foresight Ability

We need to talk about the Pale King's foresight ability

Ok, I waited a very long time to make this post. The story of the Pale King is my favorite aspect of the whole narrative of Hollow Knight, and there's so much mystery surrounding it that I can't not think about it on a daily basis. There are a bunch of questions left unanswered, and I believe that most (if not all) answers were left in the game specifically so that players could interpret them the way they think is best. So I wanna see what interpretations ARE there and maybe pick one (or two. or three. or all of them. or maybe really just one.) I dunno. Anyway, the point is, this is probably gonna be a long one. Big shoutout to anyone who makes it all the way to the end.

Now, enough with the rambling. To the point.

It all starts with the mushrooms.

The part that started all this train of thought was this particular line.

Unlike other areas of the game, Fungal Wastes don't have a boss that correlates with the area's native species. The shrooms don't have a higher being they worship. They don't have a civilization. They don't have a Dreamer. All they have is this big old mushroom elder that sleeps eternally with this one thought in their mind. All this to say that this line here is *probably* hella important.

The lore tablets of the Wastes also echo it.

So keep this in mind: when the Wyrm, reincarnated as the Pale King, started building and expanding his Kingdom (it's safe to assume that he started doing that AFTER he turned into his bug form) and got to the part where he had to make an alliance with The Mushrooms, they agreed to be a part of Hallownest ONLY because they knew that the Pale King had an ability to predict the future. Remember, they looked down on all the bugs that weren't part of their mycelium-sharedSelf-mindUnited thing. They were perfectly happy with their way of life. They didn't need the Pale King's gift of mind. The only reason they agreed to accept his will was because of his foresight ability. They assumed that, since he can see what's going to happen in the future, he will protect them (along with the rest of his Kingdom) from any possible danger. And that was a smart decision.

And yet, it didn't work out. And not just for them. For the whole Kingdom.

The main question is why.

From the way the mushrooms talk about the Wyrm, we can assume that his foresight ability didn't quite suck, which is to say that he really COULD see a big part of what's going to happen. So basically, we have two possibilities:

A. The PK's foresight didn't allow him to see *too* far into the future. It had its limitations. Maybe he could see what was going to happen in an age from now, but he couldn't predict *everything*.

B. The PK's foresight could reach as far as all eternity, meaning he knew the 'Eternal Kingdom' was doomed to fail from the moment he started building it.

In any case, Elder Mushroom's words suggest that, at one point, PK actually KNEW his Kingdom was going to fail.

And, since the most important part of his story is his battle with the Radiance (like, what else would the Mushroom be talking about?), I think it means that he potentially knew that the Hollow Knight was going to fail, but created and Sealed it anyway. So, the question is:

If the Pale King could see that his plan of creating an empty vessel to seal the Radiance would inevitably fail, why did he go through with it in the first place?

Here's the first, most simple answer.

He knew that the Infection was inevitable, so he decided to postpone it indefinitely. Hit the snooze button, but make it last forever.

Actually, that's not even an answer. This is just a straight-up fact.

Hallownest is literally frozen in time.

(Actually, I think it's so frozen that sometimes it makes rocks levitate)

The Hollow Knight's sacrifice was made SPECIFICALLY so the inevitable arrival of the Infection could be set back for all eternity. That's why the game has a big leitmotif of night and day.

That's why the Radiance's main goal is for the Dawn to Break. Because she's the Sun, and what she's fighting against is an eternal night.

But now we're entering the mystery zone. There are two questions about PK's foresight ability that have to be answered in order to understand what's actually happening.

Question 1. Does freezing time also freeze the foresight? If the Kingdom is left in a stasis without a changing future, can PK still see past that stasis? Could he see when it would end? If so, could he see what will happen after it ends?

Question 2. Is Time actually predictable? Is there just one timeline where everything that happens was doomed to happen in the first place, OR are there infinite possibilities and some room for the free will? If so, can the future be changed if one knows what actions will have what consequences? And if so, are there things that are actually inevitable, no matter the choices?

Whatever the answers to both of those questions are, I want to emphasize this:

Those lines spoken by the Radiance, along with the Elder Mushroom's words about a demise unavoidable, as well as some other things I'll mention later, make me think that the Infection and the Radiance's rise to power is an event that was truly inevitable.

Here, it doesn't matter if the free will is real or not. Remember: in the Pantheon of Hallownest, the Radiance ranks higher than the Pale King. She is a candidate for a God of Gods title, the highest of the Higher Beings. So maybe PK could shape the future with his knowledge of it. Maybe his foresight actually protected his Kingdom by preventing some bad things that he, as a Pale Being, had power over. But the power of the Radiance was stronger than that. She had the strength to assert her dominating will in every possible timeline, so that, even with his foresight, the Wyrm couldn't do anything to stop the Dawn from Breaking. After all, it's the power of Nature itself - the day always inevitably comes to replace the night.

So that's the entire reason the King decided to use the Void in his battle with the Radiance. The Forgotten Light had the ability to conquer Fate. But the Void, in his own words, had the ability to deny Time itself.

So, even if the Infection was inevitable, the power of Void could either prevent it, postpone it, or straight-up defeat it. I think that the reason for this is that the Void possesses a will that is stronger than any Higher Being. The Night and Day can follow each other, but the force that represents the End itself is beyond that.

So, now we're gonna ask the REAL question.

With the Void being able to deny Time, could the Pale King see the future the Void's actions will bring?

And for that, I have two facts that suggest that PK, in fact, couldn't at least foresee SOME of the Void's choices.

The first one is the fact that the game has multiple endings.

Look into those eyes and tell me that they're looking at something that could have been predicted and prevented by a dead monarch, albeit a godly one. The existence of multiple endings tells us that free will IS real, at least for The Knight/The Shade Lord.

Oh and speaking of dead monarchs, here's the next fact.

That man is fucking dead.

The Pale King's whole deal was to last eternally, right? To build a life that would ensure his endless reign. To achieve immortality.

So if he could see what was going to happen after he let the Void into the picture, why would he still try that despite it clearly leading to his demise?

The nature of PK's death is mysterious, to say the least. He didn't just die of old age. He tried to run away, bringing his whole Palace along with him to the Dream World. He tried to run away from something - probably from the consequences of his own actions. But even that escape didn't save him from being killed. And what killed him was most definitely the Void.

The throne room is dark.

In fact, it's so dark that the Kinght has to pull out the lumafly lantern. The only other room in the entire White Palace where that happens is the workshop, where PK worked on creating the Kingsmoulds and the Wingsmoulds. The space is filled with black smoke and black particles - the same ones that are seen in the Abyss and many areas that are located above it. When the Kinght strikes the Pale King's body with the Nail, it sounds the same as striking a training dummy outside of Oro's hut, which is made out of a lifeless husk. It's like the Pale King's body was literally hollowed out.

The form that was given to the Void by the Pale King to create the Kingsmoulds guarding the throne room is lost here, implying that it gained some other will that was beyond the Pale King's control.

And again, the only other place we see something like that is the Palace Grounds in the waking world.

...Which are located just above the Void Sea. Also, the same smoke and particles surround the place, and black tentacle-like vines reach inside the body of the Kingsmould containing the Palace.

No need to doubt. It was definitely the Void that killed the Pale King.

But what does it mean?

Well, here's some important info about the Void. It is a manifestation of this world's regrets.

If you look deep enough, it makes a lot of sense for the Void to symbolize literal regret. The Shade is a manifestation of the Knight's regrets about what went wrong on its journey. The Void Sea in the Abyss is probably the regrets of the Ancient Civilization's dead bugs. And the Void that surrounds the Palace Grounds and the Pale King's throne room is a manifestation of his own regrets. That's why he couldn't escape from the Void even in the Dream World. Because you can't escape your own guilt, your own darkness, your own regret. That's also the reason why the Knight has the right to sit on the throne after striking down the Pale King: it's because, at that point, the Kinght is set on a path that includes facing its own regrets, accepting them and uniting them under its will. Something the Pale King failed to do.

But the question remains: what exactly were those regrets that the Pale King was running from and that ultimately killed him? I mean, of course, it's the whole deal with the vessels that he regretted, but I think there's more to that. I want to lay down a list of theories about his foresight. Each of them can also explain which specific regret got him the most.

Each theory would also change the interpretation of this famous line:

...Which is important. Obviously, this line refers to the Vessels being sacrificed in order to create a Pure one, but, depending on the possible range of PK's future vision, it can have an additional, deeper meaning. You'll see what I mean.

But first, there's some other issue here that needs to be addressed, that makes this whole discussion twice as complicated. It's all about this one line:

So, here's another fucking question. Does harnessing the Void by creating the Vessels and the Moulds make those creations a part of what the Pale King could see with his foresight ability?

There's some kind of scale here that varies from 'There are multiple endings that depend on that one Vessel's choice, so that means the Void is outside of the PK's ability to predict the future' to 'The Vessels and the Moulds are the Void that is harnessed by the Pale King, so his future vision applies to them as well; it's just that the Knight gains the power to choose the ending only when it takes control over its own Void by gaining the Void Heart'. So, what if the Pale King could foresee that the Knight would be able to defeat the Radiance in the dream world? What if he couldn't see the Knight's arrival at all? What if he COULD see it, but his vision only applied to the events of the Hollow Knight ending, the only one that doesn't include the Void Heart? What if even the Embrace the Void ending was visible to the Pale King after all, as one of many possibilities he didn't pay too much attention to?

But the Knight is one thing. What about the Hollow Knight? Was its failure a part of the future PK could see? Or, since THK is a Vessel too, its choices were off limits as well? What about the Kingsmoulds? Was the fact that they would succumb to the Void that was going to kill PK available for him?

None of these questions have a clear answer. Probably. Or maybe they do. But there are multiple explanations for what was really going on. I'll try to present them as a list of theories. Each of them will give us a different interpretation of the Pale King's foresight ability's true nature.

PK didn't know what the Void would do but decided to try using it anyway.

PK only saw that the Void would help the Hollow Knight seal the Radiance, but his vision was limited (either because it was limited by its nature (option A, see above), or because the stasis created by the void limited his abilities (question 1, see above)), and so he didn't see that the Hollow Knight would break.

PK knew the Hollow Knight was going to fail but doomed his Kingdom anyway.

PK only saw the timeline where the Knight seals the Radiance without killing her. Every other ending besides The Hollow Knight was beyond PK's foresight.

PK knew that there were multiple possibilities once the Pandora's box was opened, but he saw that one of those possibilities was the Void successfully sealing the Radiance and/or killing her, so he decided to roll the dice. So he could see that Dream No More was possible, but he didn't consider Embrace the Void.

Each of these theories holds some interesting interpretations. Let's take a closer look.

I'll use a timeline to mark the possible range of PK's vision for each theory:

Just to clear things out: when I talk about what PK could or couldn't see, I mean what he could or couldn't see while using his powers at any point before his death. It IS possible that he saw some things when it was already too late to do something. That's what I was talking about when discussing possibilities A and B above (so maybe he saw that THK would break before he even made the Vessels, or maybe he figured it out only after it got sealed). Every theory accounts for that. It's complicated. You know what? Nevermind this whole disclaimer. I'll get to it.

Theory 1. The Void neutralizes the future vision

Basically, what this means is that once the Void got into the picture, the Pale King could no longer use his powers in any meaningful way. The Void, being a will that denies Time, created too many different possibilities for the King to account for, yet he decided to go through with the Hollow Knight plan just because he didn't see any other option.

The line 'No cost too great' in this case might refer not only to the Vessels being sacrificed, but to PK's foresight ability itself. The cost is his future vision, sacrificed to a state of uncertainty that might or might not bring salvation.

If this theory is true, the Pale King's story is a story about a monarch who, in his efforts to save his Kingdom from a wild force of radiant nature, accidentally unleashed something far beyond anyone's control and paid for it not only with his main ability, but with his life as well. Both the Vessels' and the Abyss' actions couldn't have been predicted, and that's why PK accidentally allowed for the Hollow Knight to break and for the forces of the Abyss to overpower him with his regrets about the countless children he murdered.

The risk he took is his main regret.

The flaw of this theory is that, if it's true, it means that:

a) The Elder Mushroom was completely wrong about PK being able to foresee the second coming of the Infection.

b) Harnessing the Void doesn't do shit besides changing its form. Even while being contained inside a semi-sentient Vessel, its actions don't bend to the Pale King's will or his foresight ability.

All in all, this theory basically means that both Pale King's powers and his judgment sucked, and the whole collapse of Hallownest happened because he was incompetent, reckless and stupid.

(That's why I don't like it)

TL;DR: The Void does what it pleases regardless of the Pale King's future vision, and he was stupid for trying to use it.

Theory 2. The Hollow Knight's failure was beyond the Pale King's future vision

This is probably a very controversial one, but it does have some interesting implications. The point is that PK didn't see that the Hollow Knight would fail, and so he went through with the plan thinking it was flawless.

In this case, the Hollow Knight counts as a 'harnessed' part of the Void, so its actions up until its breaking were completely predictable. The Pale King saw that the Infection would be sealed successfully, and that a stasis would be created. He got what he wanted, but at some point (could be any point) he realized that he didn't know if anything was going to happen next.

That could happen for one of the two reasons:

The stasis created by the Pale King literally meant that the time was frozen, which meant that nothing relevant wasn't going to happen unless this stasis would somehow break. But, while inside this state of stasis, the Pale King himself couldn't see anything beyond that state. What future vision is there if there's no actual future?

The future vision was clouded by the Pale King's inevitable death. It's possible that, while looking into the future, PK couldn't see the Hollow Knight breaking simply because his future vision doesn't allow him to see beyond the moment of his own death.

Anyway, what this theory suggests is that the main thing the Pale King didn't or couldn't predict was his own death. Or maybe at some later point he saw it was coming and tried to run away from it by hiding his Palace, but the Void got him anyway. It happened because the Void that destroyed the Kingsmoulds' bodies and killed the Pale King was a force beyond anyone's control an beyond PK's foresight.

A major proof of that is the situation with this guy:

Notice how they apologize directly to the Pale King, and how the Void slowly took over their mind. This guy was a royal retainer, which means the King probably ordered them to keep the lighthouse running himself.

The question is, why did he take such a half-assed measure to keep a whole Sea of raw dark power at bay? It looks so stupid! Just one lighthouse for a whole unchecked Void Sea? And just ONE lighthouse keeper who couldn't even resist the Call of the Void? Why such carelessness?

The answer is right here. That was because the Pale King simply DID NOT KNOW what the Void Sea was actually capable of, because its power (unlike the power of the Void trapped inside the King's children's bodies) was beyond his foresight. Without a clear answer from his future vision, he figured that this Void might or might not be an issue and decided that he had more important stuff to deal with instead of even hiring a whole team to watch one lighthouse.

So, while he managed to reach his goal creating a stasis that would keep his Kingdom lasting eternally, there was one thing he didn't account for, and that was the vengeful wrath of the dark force he dared to use as his plaything. The lighthouse was turned off, and the Void soon started to rise up through the rocks of the Ancient Basin towards the White Palace. The King tried to run, hiding himself and his Palace inside the Dream World, but the Void seeped in easily, killing the monarch. After all, the Kingsmould that was used as a gate to the Palace was also made out of Void.

If this theory is true, then the line 'No cost too great' could refer not only to the Vessels, but also to himself. If he didn't know that the Hollow Knight would break, then he probably thought that his Kingdom WOULD last forever, and that even his own death wouldn't change that. So he sacrificed his own life, gave in to his regrets about everything bad he had done, but managed to save one glimmer of pride, thinking that, even though he killed a bunch of children and abused the Void, he still managed to deliver eternal happiness to all his subjects.

But the thing about this theory is that now we also need to explain why the Radiance broke free despite everything the Pale King thought he did. Here, this theory divides into two additional theories (I'm really sorry for this long-ass post):

Theory 2.1: The Radiance is like 'Nah, I'd win'

Basically, PK's plan to achieve eternal life for his Kingdom at the cost of his own life was actually good. There was no flaw in it, and it should've worked perfectly. But we know that the Radiance might be a being that is higher than PK on the power scale. So, just like the Void, her actions might be beyond what PK's foresight ability could help him see. PK did everything right (not morally), but the Radiance broke through anyway because she's just... that much better.

Theory 2.2: The death of the King is what triggered the whole thing

Going back to the Void's actions messing with the future the Pale King could predict, I say it's possible that his own death, caused by the Void, is what made the stasis wear off.

Think of it this way. The Hollow Knight contained the Infection, but that merely eliminates the possibility of a HIGHER FORCE enacting some sort of change. Preventing EVERYTHING ELSE from breaking the stasis is the job for the Pale King himself. But, once the Void (another higher force) kills him, there's no one that could keep the stasis running, and it just... ends. That gives the Radiance (as a force of change, opposed to a state of frozen time) an opportunity to break free.

Or maybe it was the Sealed Vessel that was affected by the Pale King's death. After all, we probably know what its only thought (the one that ruined everything) was:

So, the Pale King dies, the Hollow Knight senses that a familiar presence is starting to slip away, which makes the Vessel panic (or something like that), and the Radiance makes her move, infecting its mind.

OR it could be both of those things! Maybe the Hollow Knight's attachment to its father AND the Radiance's insane higher power both played a role in filling up the power vacuum that was left after PK died.

Anyway yeah, that's it for this theory. The only thing left to discuss is the new interpretation it gives us for the line spoken by the Elder Mushroom:

'A demise unavoidable', in this case, refers to the demise of the Pale King himself. He didn't necessarily foresee that his death would lead to the destruction of Hallownest, but at some point he might've figured out that the Void was coming to get him but decided to stick with his plan anyway. But then it raises the question of when and how the Elder Mushroom learned about the Pale King's demise, and why they assumed that he could see it coming. That's the main issue with this whole theory: it just doesn't explain how the Mushroom's line fits into all of this.

TL;DR: The Void killing the Pale King is the only thing that he couldn't foresee in the long run, and even if he could do that at some point, the consequences of his death AND/OR the Radiance's actions were beyond his control.

Theory 3. Self-fulfilling prophecy

Ok, so now we're on the theory that I personally consider the closest to canon, or at least the implications of canon that we have. This is also the one theory that brings (some kind of) consistency to this whole question. This is because it explains the earlier question of how the future vision actually works.

See, there's no way the Pale King actually knew that the Hollow Knight would break from the very start, right?

Why would he doom his Kingdom when all of his actions were meant to prevent that? In fact, that's exactly the question that the Elder Mushroom is asking.

"Pale Wyrm... What good to foresee a demise unavoidable?"

Well, the answer here is actually kinda simple this time.

He saw it coming, and he tried to postpone it.

This is the simplest explanation possible, because we already have all the proof right here on the table.

The King sees that the Infection will come, and that it is inevitable (the inevitability is the key part).

He knows that, when the predicted moment comes, the Radiance will return and wreck his shit. No matter the timeline, no matter the choice. The flow of Time itself inevitably leads to the Infection happening.

The only option is to use a force that is able to deny time itself. The solution is to use the Void to metaphysically freeze the very flow of Time itself. The plan is not to try to change what is meant to happen, but to create a stasis that makes it so that it never comes to it. The timer never reaches zero. The eternal snooze button.

The stasis, however, dampens the foresight ability. If there's no flow of Time, the King can't see what's going to happen.

[A little digression: For the purpose of proving this theory, let's say that the foresight ability works better the closer the observer is to the moment that is being observed.

For example, while looking into the future from a point in time before a big war, the observer CAN see that the war will end on a certain date, but only when that date comes closer to them can they see HOW the war will end, and WHO will end it, and any other detail.]

The stasis wears off because of the Radiance's power (like in theory 2.1).

The King is finally able to see the exact nature of the Infection breaking free. He sees that the Hollow Knight itself, the Vessel he personally created to be the only key to the Kingdom's salvation, will be the reason everything goes to hell.

Wracked with guilt and regret, he escapes to the dream realm before the break happens so that he can at least save himself and his palace.

The Void makes a move that the King could or couldn't foresee, killing him. He thinks about the 'no cost too great' philosophy one last time before realizing that it is, in fact, utter bullshit. He dies with a feeling of everything he built crumbling to dust and his core belief being proven faulty.

The Infection breaks free, having harnessed the Hollow Knight, as inevitable as always. With the King being dead, there's no power to uphold the time stasis, which becomes the final push. The Vessel breaks.

Only then the Kingdom sees the arrival of a void being that has the potential to actually change things from their set course. The Knight, being a part of the Void that was beyond the Pale King's future vision range, enacts an end of its own choosing.

This ties to the game's themes of determinism, and flashes out the Kinght's strength to break free from the fate's chains, empowering the player and making the whole plot twist with the final battle against the Radiance even more epic.

The monarch who justified killing his own children by his desire to prevent the higher will from destroying his artificially made Kingdom has succumbed to a force beyond his control, becoming a part of a self-fulfilling prophecy. The chosen hair of its father's will becomes the reason why the inevitable finally happens. The only one who is free of obligations, desires and beliefs becomes the one to save the Kingdom once and for all, avenging the deaths of its kin. Beautiful.

And the Mushrooms who probably just didn't believe in the stasis from the start turned out to be right, smugly reminding us that it was always inevitable and PK couldn't do shit. There's no good in seeing a demise unavoidable, and it's foolish to make sacrifices to postpone it.

What the Pale King lacked was acceptance. The ability to embrace the true nature of things.

Something that is the main ability and the main character arc for the Knight, whose nature is to consume and to use its will to make even the darkest shadows become a part of it.

A little spoiler though: this theory has another variation that is even cooler. I'll leave it for the very end.

TL;DR: The King knew that the Infection was inevitable from the very start. He tried to postpone it. He failed, becoming a part of a self-fulfilling prophecy. When he figured it out, it was already too late, so he fled and was then killed by the Void.

Theory 4. The Masterplan

Ok, so, while the previous theory was probably the one closest to the canon implications, there are still a couple of possibilities that make this WHOLE thought process worth the time spent on it, because the mere CHANCE of this one theory being true makes the whole game feel even more nuanced. It's not even necessarily correct, but it's not about that. Team Cherry made the lore surrounding the Pale King's foresight ability vague enough for us to feel it's POSSIBLE that the whole plot was predicted by him. And that's how this narrative works: it allows the players to come up with different interpretations of itself, never proving or disproving any of the theories that it inevitably creates inside our heads.

So anyway yeah, what if the Pale King knew that another Vessel would usurp the Hollow Knight? What if THAT was his plan all along?

So, let's discuss a very important question.

How was the Hollow Knight chosen among other vessels? Why did that one child become the Pure Vessel while millions of others were left behind?

Well, judging by these lines and by the Birthplace cutscene, the trial to be chosen as the Hollow Knight was to climb up from the Abyss.

But why? How does scaling a huge pit prove a vessel hollow, and devoid of thought? Is it about the strength? Is it about not caring about other siblings who fall down? Is it about controlling one's inner Void in order to not succumb to the regret of the whole situation? Is it something like a sperm and an egg thing? A bug thing? Maybe it's all of those things. Maybe it's none of them. One thing we can assume, though, is this:

The Knight also passed this trial. It could have become the Hollow Knight. The reason it didn't was because the Pale King didn't see it and the Hollow Knight didn't care about it.

But in the end, it was the same reason why the Kinght became a more worthy candidate.

Think about it this way. If the Void is what is needed to seal the Light, and if the Void is created and channeled through regrets and past pain, what could be a better fuel for it than a father's abandonment and a sibling's indifference? Passing the life's trial but losing a chance to live anyway creates the strongest darkness, and that darkness is the reason the Knight becomes the best Vessel possible to do this task.

But it's not the only trial the Knight had to pass in order to qualify for this role.

(Notice the phrasing used in the Quirrel comic - 'ascend to that fabled land')

We don't know how it happened (Team Cherry teased us once about revealing it), but the Knight not only escaped the Abyss through some other path, but managed to leave Hallownest and then come back, purified by the mind-wiping winds. That's what Hornet says about it, too - she specifically states that the Knight's resilience was born of two voids: the one that's outside of the Kingdom and the one that's below it.

And we also know that many other Vessels attempted the same thing.

So basically, had any of them been more successful at the quest the Knight did succeed at, the Kingdom could have had a greater, if not near-infinite, amount of replacements for the Sealed Vessel. One Knight takes the Infection inside of itself, holds it in until the Infection inevitably starts to break free, but then another Knight arrives, answering its sibling's call for help, and the cycle continues. Convenient, huh?

Sounds like a thing some very perceptive godlike monarch could come up with as a plan to save his Kingdom.

It could ALSO explain why there are SO MANY Vessels in the Abyss. Maybe it's not about the White Lady being crazy horny. Maybe it was a part of the plan (which included the White Lady being crazy horny) all along. A way to measure up to eternity by creating an amount of heirs that no one would be able to count. Yes, it IS finite, but with THIS many spare Vessels it wouldn't really matter.

That said, there ARE some flaws in this theory. First, there's no live Vessels in the Abyss, so the ones that survived the Pale King's trial probably either died or left the Abyss already. And it's likely that there weren't too many of those who escaped, so maybe there weren't enough vessels after all. But then again, it only takes one to save the Kingdom for multiple ages, so who knows how that would work.

Second, as far as we know, the Knight was the only one who had the potential to actually seal the Radiance once and for all. Letting weaker vessels try to usurp the Hollow Knight would mean risking the Kingdom. But then again, that's what Hornet was there for. On the other hand, even she was surprised with how the Knight was able to defeat her, so either she didn't know about the Masterplan, or it was never real in the first place, and the Knight IS the one unique Vessel who has the strength to save Hallownest for good.

Honestly, I'm inclined to agree with the latter assumption solely because of the narrative weight of the Birthplace cutscene. I mean, there was no other vessel that was in the same position as the Knight. No one else had that same experience of passing the Abyss trial just in time to see the first Hollow Knight walk away with its father, who then shut the door in their face.

But anyway, this theory is still pretty valid. If it's correct, it would mean that:

a) The 'No cost too great' line spoken by PK at the moment of his death basically means 'Whatever bitches, I may be dead but Hallownest WILL last eternally because I had those Vessels ALL FIGURED OUT, and there's SHIT you can do about it now!'

b) All who doubted PK's plan are proven wrong, and the Mushrooms' smugness is worth nothing.

c) The Pale King's future vision is fucking OP.

...Whiiiich yeah, makes the Pale King look like the coolest mastermind in all fiction, but at the same time takes away the tragedy of his whole story and the uniqueness of our dear beloved Ghost Knight. Still fun to think about it tho.

TL;DR: The King knew that the Hollow Knight would break, so he had every other possible Vessel in mind as a replacement. The new Vessel would be the one who survived the Abyss, escaped, left Hallownest, and returned at the call of the previous Vessel. With millions of Vessels born, the cycle could have been repeated so many times that it wouldn't matter when the Abyss would run out of Vessels.

Theory 5. The Masterplan but cooler

Now THAT's what I personally consider a big stretch.

See, for THAT theory to be correct, the Pale King should have known the EXACT moves the Knight (and only the Knight) would take in order to defeat the Radiance one way or another. He should have accounted for things such as:

The Knight being left in the Abyss in the exact way that it was; broken mentally by the chance that was taken away from it.

His own death.

The Knight arriving to Hallownest, passing all the tests, getting the Dreamnail, breaking the Dreamers' Seals.

The Knight becoming the new Sealed Vessel in at least two of the possible timelines.

The White Lady gifting the Knight her part of Kingsoul.

The Knight successfully entering the White Palace, finding the King's corpse, and taking the second half of Kingsoul.

The Knight returning to the Birthplace, getting the Void Heart and uniting the Void.

The Knight entering the Hollow Knight's dream with Hornet's help and actually killing the Radiance by making the Void consume it.

I think there's exactly a 0.00001% chance of that being the case. But hey, it's possible!

Actually, I don't believe that. It just doesn't feel like that's what the canon implications are about. And then again, if that theory is correct, why couldn't the King predict the Embrace the Void ending? And I do believe that SHADE LORD wasn't on ANYONE'S bingo card at all (except for maybe that one goth bug who gives us the Shade Cloak). Or did the King just decide to risk it all by defeating one God of Gods by creating another, much stronger one? I really don't think so.

I think the Void's will, as well as the Knight's, has the nature to defy any type of fate or future vision. And once the Knight gains the power of the Void Heart, the future of Hallownest is entirely in its hands, and its choice is now inherently outside of anyone's foresight.

TL;DR: The King predicted everything. Could he predict the Shade Lord though?

Theory 6 (the secret one). The 'human' factor

Ok, so, up until now, I discussed the possibilities the Pale King had with his future vision, and how said possibilities could influence his actions and the history of Hallownest as a whole, with the Self-fulfilling prophecy theory (of which this one will be an extension of) being the most plausible one. There's just one thing though. None of those theories really accounted for the possibility that, at some point, Pale King could've just not used his powers, or, more realistically, used them but chose to do something despite the information he got.

But why? What could possibly make him do that? The literal God of Mind, not being rational? Sounds like something that Team Cherry wouldn't fail to include in the game as an emphasized plot point. A lore piece so important must've been given some significant place, perhaps even locked behind some insane platforming gauntlet...

I swear, this one moment drives me crazy.

The Pure Vessel. The Sealed sacrifice. The Empty God. The Hollow Knight was created to be the one and only savior of Hallownest, of everything the Pale King worked so hard on. It was created not as an heir to its father's throne, not as his child, but as a tool to win a war that had been going on for ages. And we all know that it failed because it gained a mind, a will to live, a desire to crave happiness.

And this moment at the end of Path of Pain tells us exactly how it happened. The Pale King, being a god whose main power is to give bugs the ability to think, shared exactly one moment of pure fatherly affection with his empty creation. And that's all that was needed to plant the seeds of a mind-conquering disaster.

And right now I want to focus on the Pale King himself here. If you watch the cutscene, you'll notice that he is the first to turn his head towards the Hollow Knight. He was the one who initiated this moment.

And one might ask: why? Didn't he know that that could lead to the Vessel having a thought that was terminal for the whole plan? Couldn't he PREDICT that him showing even an ounce of affection towards this hollowed-out child would ruin everything he built? His whole Kingdom, his whole dream, his whole civilization? WAS HE STUPID?

But hear me out. What if what we're looking at here is not the Pale King messing up his entire career as a monarch, but him actually achieving the only thing that could satisfy him? Think about it. Who knows how much time he spent in his workshop trying to harness the Void. Millions of his children were left for dead, locked inside a horrible bottomless pit as bones and shadows. Three of the Kingdom's greatest bugs agreed to sacrifice their lives for the King's plan. All so he could achieve what he considered perfection. The impossible ideal. All the struggles of this Kingdom led to the creation of that one being. And when the Pale King knew he had succeeded, there was nothing left to strive for. Finally, he could allow himself to be satisfied. To forget about the greater good. To forget the never-ending battle. To live.

To love.

And maybe at that point he refused to use his future vision. Or maybe he knew that this would ruin everything. Maybe he always knew. For that moment, none of it mattered. The god of mind finally experienced something that had nothing to do with rationality. And once that happened, nothing else mattered anymore. No cost was too great for this one moment.

And so, nothing that happened after that mattered as well. The King's radiant enemy would soon take his Kingdom. His beloved Queen would go into exile. He himself would not be able to fight the regrets of his dark past and would soon cowardly flee from the waking realm, only to be killed on his throne by the very power he so foolishly used to achieve his goal. But at that point that goal didn't matter to him anymore. He was ready for the eternal Void, because he had already achieved the only thing worth achieving.

Too bad that meant he would doom millions (if not billions) of live creatures and make the only being he could actually love experience the cruelest torture unimaginable. Too bad that, when gods attempt to achieve a higher ideal, countless souls must suffer. Too bad that because of that one achievement everything Hallownest was had to end.

But everything ends at some point. That's one of the main themes of this game, and the idea that I believe is represented by the Void. The Knight arrives to reap the sins of its creator, witness secrets sealed, bring some hope to a ruined land, and enact the end of an era. Only a silent agent of change is there to witness the dark consequences of the Wyrm's quest for happiness.

Neat theory, right? Now guess which one is my favorite!

TL;DR: The Pale King realized that the act of loving his child is worth sacrificing everything he worked for, so, even knowing that sealing the No-More-Hollow Knight would doom Hallownest, he decided that his life has already peaked anyway and that there's no point in trying to do anything anymore. He knew that he was cooked though, so he fled and died only with the closest circle of family and friends to keep him company.

The post is over now. Big, bigger, yet bigger, the biggest thanks to anyone who genuinely made it through to the end. My grammar is probably flawed as fuck tho, because English is not my native language, so please cut me some slack in that regard. I hope what I was saying there was at least somewhat cohesive. I also hope that the more obscure bits of information I used (like cut dream dialogue) didn't throw anyone off the thought train. It's probably gonna be a big deal when I release this post, so I probably will be coming back to it. Any discussion, as well as disagreement, is always welcome! Please just let me know I didn't write all this for nothing lol. Thanks again!

TL;DR: Skill issue.
