[[WMG: The Nameless One's true name is [[spoiler:Calvin]]]]
and his crime wasn't a NoodleIncident, it was [[spoiler: THE noodle incident]].

[[WMG: The Nameless One is a [[Literature/TheElricSaga facet of the Eternal Champion.]]]]
The TabletopGame/{{Planescape}} setting already features a massive conflict between [[OrderVersusChaos Law and Chaos]] (The Blood War), and The Nameless One happens to be a tragic, extremely powerful individual condemned to fight that war for eternity (Or at least, until the Planes die off). The ''TabletopGame/DungeonsAndDragons'' multiverse could very well be a part of ''the'' Multiverse.

[[WMG: The secret to the Nameless One's memory was the invocation of the player.]]
The incarnation that discovered a means by which the Nameless One's memory could be preserved between deaths hit on the critical importance of the player in determining the outcome of tabletop and video games. He arranged it so that Planescape: Torment would be created in our world, but by the time it was released he had died a few more times, leaving us with the playable incarnation. The reason the memory endures is because the player is there to share the memory. However, the incarnation wasn't the only smart character wandering around; anyone capable of outright killing the Nameless One has, through madness or transcendancy, mastered the blackest art: that of the Game Over.

[[WMG:The Nameless One's name wasn't Adahn.]]
It was [[Literature/TheBible Adam]].
* That... makes a [[FridgeHorror terrible amount of sense.]]
* This may be my favourite theory I've ever read on WMG. To expand on the points in favour: if one assumes the Christian parallels fit, this slots neatly into the First Incarnation's story, as he commits a sin so grave the planes have been dying ever since. As mentioned, the Nameless One always lies that his name is Adahn, and when discovering his name realises that it's a simple thing, and not what he expected - the name Adam being deceptively simple. Further, this puts a new spin on the game's central question: "What can change the nature of a man?" Adam means, essentially, 'man'.
** And from a bit of a meta perspective, the answer the game essentially gives you (the player) is "your choice." From certain theological perspectives, Adam and Eve chose to exercise their wills and disobey God. This one DOES make a scary and remarkably awesome amount of sense.
** It makes me wonder what happened to Eve, though.
** It also means that the Nameless One simultaneously fulfills the role of Christ, at the end.
** Also, mind-bendingly enough, the [[https://en.wikipedia.org/wiki/Gordian_Knot Gordian Knot]] is an item you can find in Curst, described as being from "a distant Prime Material world." This means our world (or at least, a mythic version) is definitely somewhere in the universe of Torment.

[[WMG:The Nameless One's name is Torment.]]
Less brilliant, but like a [[Series/DoctorWho certain other nameless, centuries-old living myth]], the Nameless One might be the origin of the word Torment, it having come to mean what it does only through association with his actions.

[[WMG:The Nameless One's original crime was the instigation of the Blood War.]]
A crime so massive and downright evil that the planes seem to be slowly dying of it? The Blood War fits the bill well enough. Far back in a time before even surviving myth, the original incarnation instigated the Blood War for fun, profit or an ideal, and ended up causing a tumult that would endure for millenia, killing thousands by the hour. Therefore his ultimate fate: to fight as a soldier in a war of his own making.
** The problem is that the Blood War has never had much in the way of collateral damage. It's always been contained to the lower planes, and is viewed by most everyone as a ''positive'' thing. It keeps the demons and devils occupied so they don't conquer the multiverse.
*** Yeah, the Blood War is a ''good'' thing. It keeps the demons and devils fighting each other instead of overrunning the rest of the cosmos.
*** According to canon source material, the Baatezu and Tanar'ri first met millennia before they discovered man, which means the Blood War probably predates mortals.
* Alternately, he is the reason the Blood War is ''necessary'' in the '''first''' place. He is the reason why fiends outnumber celestial by so much, why Good Outsiders, naturally-occurring and independent from deities in terms of both creation and growth (like [[http://www.d20srd.org/srd/monsters/lillend.htm lillends]]), are so much rarer than similarly natured Evil Outsiders. Somehow, the Nameless One fundamentally and permanently shifted the BalanceBetweenGoodAndEvil towards the side of evil. What else could condemn a man to hell, no matter how much he changed as a person or did to make up for it?
* Why is everyone saying that the planes are slowly dying because of his original crime? I understood that his original crime simply damned him to fighting in the blood wars for eternity regardless of his actions afterwards. The planes are not dying because of his original crime, they're being slowly, very slowly, drained of lives by his immortality forcing death to take other people instead of him.

[[WMG: Branches of the Ravel tree include...]]
Chris Avellone has said that Ravel's existence spreads through the planes like the branches of a tree. The other incarnations that appear in Planescape echo her existence in small or large ways. Due to the nature of belief on the planes, these incarnations may not ''start out'' resembling Ravel, but they come to resemble her in their lifetimes. Here are some from other planes:
* IcewindDale: The blind seer and the cat lady of Targos (confirmed by Chris Avellone himself)
* ''VideoGame/DragonAgeOrigins'': Flemeth, an old hermit crone with intense magical powers and extraordinary longevity
* VideoGame/{{Fable|I}}: Theresa, blind seeress possessed of incredible longevity and arcane magical knowledge
* KnightsOfTheOldRepublic: Kreia, twisted blind seeress possessed of arcane magical knowledge. For bonus points, written by Chris Avellone and imbued with some elements that didn't make it into Ravel's character.
* VideoGame/FinalFantasyI: Old and insane blind seer, Matoya
* Franchise/TheDarkTower: Rhea of the Cöos
* VampireTheMasqueradeBloodlines: Pisha the Nagaraja, a flesh eating vampire living underneath an abandoned hospital, with a vast knowledge of magic and the future.
* VideoGame/SilentHill1: Dahlia Gillespie, evil, demonic witch extraordinaire. Dahlia is probably only just becoming one of Ravel's avatars, and the first hint is her looking ancient while really being only 40.
* VideoGame/{{Dishonored}}: Granny Rags, the blind old witch who lives in her apartment, with magic powers and [[spoiler:control over the plague rats]].

[[WMG: For about five minutes of the Good Ending, the Nameless One was the most powerful being in the multiverse.]]
The Nameless One's last acts before he accepted his ultimate fate were to revive his companions, speak with them one last time, and open portals to send them back to Sigil. For those who might not know what this means, the Nameless One created portals to the city where ''no'' portals are created without the permission of the Lady of Pain herself. For the brief span of time between joining with the Transcendent One and his descent into the Blood War, the Nameless One could casually ignore Her Serenity and create changes in her city against her will. If he could do that, it's possible he had the power to undo his own punishment... and chose not to.
* You can cast Gate to go to Sigil any time you like. In fact, you can cast Gate to get ''out'' too. It just so happens that most people can't cast ninth-level spells.
** If PST follows the rules of {{PlaneScape}}, Gate ''cannot'' penetrate the Lady of Pain's defense. Nothing can. If twenty gods teamed up to batter down her barrier, it would result in twenty very frustrated gods.
*** More like twenty very dead ones. Her Serenity doesn't take deities messing with what's hers well. Remember Aoskar.

[[WMG: The Nameless One is the father of Cyric.]]
How else could a mere human kill a demigod (Bhaal) unless he had the blood of an immortal coursing through his veins? Yeah, Godsbane helped, but only so much. Considering that several of TNO's incarnations had had a [[ManipulativeBastard way with the ladies]], it's not hard to imagine TNO from getting one (or several) pregnant.
* Godsbane...the avatar of the god Mask? Helped only so much?

[[WMG: In life, Morte looked exactly like Joe Pantoliano.]]
Not just because the guy usually plays archetypal traitors and liars, but because of his role in ''Film/{{Memento}}'', which, without going into spoilery detail, is broadly similar to Morte's in Planescape. On top of that, they even act and sound similar, with the same outward DeadpanSnarker front.

[[WMG: The Nameless One's sin was creating Coaxmetal]]
Because I can't think of any worse crime than creating a entity that desires to destroy all universes, and succeeding in many of its attempts. Of course, it has probably forgotten its maker, and now attributes entropy as its creator and commander.
* After more study of the Planescape setting, I shall elaborate. The Nameless One was formerly a fanatical Doomguard, and created Coaxmetal as the ultimate tool of entropy. However, he abandoned the Doomguard after realising what he had done.
[[WMG: Fell was supposed to be able to join your party]]
Because it just makes so much sense. All the other party members have their own contradictions (a chaste Succubus, an enslaved Gith, and so on,) and so the idea of a Dabus who has fallen out of favour with the Lady of Pain fits so well. In addition, there seems to be something missing from Fell's Tattoo parlor. He's a guy who knows you, tattoos play a massive part in the game, he's relevant to your back story. Plus he's interesting. Maybe I'm wrong, but I just get this incredible feeling that, at least in one stage of development, they had Fell down as a potential party member.
* Hell, I'd rather have him as the healer than Fall-From-Grace. I'm totally going to mod him in as a party member.
* Fell was a canon NPC in [[{{Planescape}} the source material]], so that might explain why he's so well developed.
** Specifically, Fell was the first (and so far only) Dabus to worship a god. He chose to become a worshipper of Aoskar. The Lady didn't take that well. At all. That is why Annah is so afraid of him.
[[WMG:The Nameless One's incarnation name for the player character, should the events in the Negative Plane be told from the perspective of the other incarnations, will be The Inquisitive Incarnation]]
In fact, this aspect of his nature is what allowed him to get so much further than any other incarnation. His power to make people who are about to kill him stop and answer any questions he might have. This is most obviously demonstrated by the demon that accosts you in Curst's underground. He wants to eat you, but he feels compelled to stop and answer your questions first.
* It also makes sense as far as the fact that he's the only one who can retain his memories goes. His mind has been broken so often that there is nothing left to break, leaving him with an empty mind, brimming with questions and longing to have them answered to fill that empty void that is now his existance.

[[WMG: The Nameless One is Tharizdun.]]
He isn't chained, he's ''forgotten who he even is.'' Explains a lot.
* Alternatively, going by 4e ''TabletopGame/NentirVale'' story, The Nameless One is the person who originally made contact with the Obryith lords; he was a follower of Tharizdun and established a link between his god and the original demons, which lead to the shard of evil being forced into the universe, lead to Tharizdun going mad, lead to the creation of the Abyss itself, the primeval war between law and chaos, and eventually the Blood War and now the Abyssal Plague.

[[WMG: Vhailor is an homage to the [[Literature/TheWonderfulWizardOfOz Tin Woodsman.]]]]
He's heartless, he used to be human, and he carries an axe.

[[WMG: The ending is the beginning of the end for the Planes.]]
Think about it: petitioners retain no memories of their former lives, and petitioners sent to fight in the blood war are incarnated as grotesque creatures like Lemures (see the original campaign setting material if you don't believe me.) When the Nameless One wakes up in the Grey Wastes, he's still in his human body, and his remembrance of Ravel's words suggests he still has his memories. This is a Very Bad Thing since the Nameless One now has the memories and abilities of over a thousand lifetimes. Either side of the war he joins will have a serious advantage, and this may even lead to the end of the Blood War. The campaign setting material makes it very clear that the Blood War is the only thing keeping the Demons and Devil's from attacking other plains. Therefore the Nameless One's reclamation of his mortality ended up dooming all of reality!
* Ao is really an idiot.
* Except, depending on your ending, he's ''not'' guaranteed to join either side. In the best ending, I expect him to keep being good.
* Jossed. The Blood War ends in Fourth Edition, and the Planes are just fine.

[[WMG: the punishment at the end is entirely voluntary on The Nameless One's part.]]

OK, this may not seem like much, but upon arriving in the hellish Planes, he picks up a weapon, nods and goes into battle. Sure, it could be a "yeah, that's a neat weapon" nod, or a "OK, let's go kick some ass" nod, but in a story where many little details seem to have real significance, this little gesture suggests that he's making a decision. So he has a choice. Then, just perhaps, The Nameless One has kept his incredible power but, after remembering his past lives, accepts that he has to redeem himself. Note that - as mentioned above - he keeps his human body, that there is a "what can change the nature of man?" voiceover, and that he didn't seem to die before undergoing his belated punishment - it looks like he was pulled bodily into another plane. Hence he probably didn't forget things. And knowledge, like belief, seems to be a very important thing in the Planes. And lastly, but very importantly - why would the Nameless One lose his incredible power? There is nothing that indicates he did.
* It certainly makes sense to me. After all, how does The Nameless One gain the memory in the bronze sphere? By feeling regret. How can he take full advantage of it? By '''accepting''' the regret, accepting all the evil, all the sins, all the pain his existence has caused to the point where he can weaponize it. Honestly, if you went through all that, the only logical conclusion is that he would, upon feeling full and complete regret for all his incarnations' actions, willingly take the punishment upon himself.

[[WMG: ''Planescape: Torment'' is a sequel of ''VideoGame/BaldursGate'']]
The Nameless One is the [[HalfHumanHybrid Child]] [[AnythingThatMoves of]] [[DoubleStandardRapeDivineOnMortal Bhaal]] if he were a Human male, followed the evil path and chose to remain a mere mortal being. After some times, he began to regret his deeds, and found a way to become immortal, so he would have the time to fix his numerous mistakes. [[GoneHorriblyWrong It went horribly wrong]]...

[[WMG: The Nameless One is [[Series/DoctorWho the Doctor]]]]
[[http://everything2.com/user/Hazelnut/writeups/The+Doctor+is+the+Nameless+One+from+Planescape%253A+Torment Read the full story here.]]

[[WMG: The Nameless One is Perrine, founder of the Godsmen]]
Because it would be [[DeconstructorFleet just like this game]] if the founder of the Godsmen started that faction based on nothing more than the desperate hope that even someone like him could escape damnation and attain divinity.

[[WMG: Alternatively, The Nameless One founded every faction, or at least every faction he can join during the game]]
When he saw how the conflict between his factions, each of which was founded with the best intentions, was tearing the planes apart, the Good Incarnation repented of what he had done, and realized that he might need several lifetimes to make up for it. This would also explain why he feels no disconnect in joining any or all of them in a single playthrough.

[[WMG: The Nameless One's great sin was ''pride''.]]
The belief that ''your'' sin is so horrible that it, alone of all sins, is unforgivable, is itself the sin of pride. He probably did something genuinely very bad, but was too proud to seek forgiveness. That's what led him to Ravel....

[[WMG: Morte is Bob from Literature/TheDresdenFiles.]]
A perverted skull with only a tenuous grip of common morality?

[[WMG: The Nameless One's real name is Gith.]]
Lemme get the first big problem out of the way. When the Nameless One learns his name, he muses that it's "a simple thing, not at all what he expected," and remarks to the Good Incarnation "That was my name all along? But if I was-" As if he knew the name, had heard it before a number of times, but had thought it impossible to be his. Because it belonged to someone supposedly of the opposite gender, for example. History got mixed up a little somehow.

Gith created and led a race of xenocidal, slaving sociopaths - more than enough to condemn someone to the Blood War. The last thing Gith did before dropping off the radar forever was descending into the lower planes - officially to gather allies, but actually to seek Ravel's aid in attaining immortality. Why would he tell the truth to a race her regretted creating? And every Githyanki in all the planes knows instinctively that, somehow, Gith lives, but is lost to them.

* Debunked: Gith was a female, this is why the Githyanki society is a matriarchy, it's mentioned often in the Gith tribes lore. Githzerai aren't because while they respected her as the hero who freed both tribes (which were one at the time) they chose to follow Zerthimon's (Gith's right hand man in the uprising) path of neutrality over Gith's plan of "Let's be a dick to everyone now because we were slaves".

[[WMG: Yemeth was the Nameless One's first incarnation, or at least a very early incarnation.]]
Although the content was dummied out for the most part in the released game, Yemeth was canonically an incredibly powerful wizard who created a pendant that supposedly made the wearer immortal by consuming souls. Now, does this sound at all like how the Nameless One's present form of immortality functions?
Furthermore, the name is brought up in relation to the Nameless One twice; once in the Tomb of Death that the Paranoid Incarnation created, a second time when speaking to the Pillar of Skulls. In both occasions, the name is brought as the last of a list of appellations or titles referring to the Nameless One's past. This suggests that Yemeth was, if not the very first incarnation of the Nameless One, than one of the first.
* Chris Avellone has stated that Yemeth is not the Nameless One's original name, though he did acknowledge that Yemeth could have been a past incarnation of him.

[[WMG: The Nameless One is the admiral responsible for the destruction of an entire world recorded in the Sensate Stones.]]
Think about it. First, the First Incarnation is said to have felt a tremendous amount of regret, which led him to seek immortality. Now, the stone that shows this memory is described as the one the Sensates use to feel regret. Next, we are talking about a crime (the destruction of a world) that seems more adapted to a sci-fi setting than to the Planescape one. It makes sense, however, if you imagine that the destruction of an entire world in a Multiverse where real, material worlds are ... well, now there is only one, would definitely uspet the balance between Good and Evil, causing the decay of the Planes that the First Incarnation feel responsible first. That theory also explains how the Nameless One could recognize his name when he finally finds it (although it doesn't explain the rest about how it is a simple thing, I admit). Anyway, it's only a theory.

[[WMG: The First Incarnation was responsible for the death of the first [[ComicBook/TheSandman Despair]]]]
Despair's killer was described as taking the rest of eternity to die, and this seems to be The Nameless One's fate until he's able to break it, the end result of which is being condemned to the Blood War regardless. Killing an aspect of one of the Endless would likely be a monumental enough crime to fit the one described in the game. In terms of world-building, tone and theme, the universes of Planescape and The Sandman would mesh well.

[[WMG: The First Incarnation did nothing [[PokeThePoodle exceedingly horrendous at all]]]]
But since the Planescape universe runs on ClapYourHandsIfYouBelieve he basically convinced himself that his deed was so [[MoralEventHorizon vile]] that eternal torment that no amount of good deeds will make up for is the appropriate punishment.
* THAT is utterly brilliant
