Considering I already put a spoiler alert please don't continue to read unless you at least have played the game once.

Now, to the matter of the game. While it didn't strike me as a surpise that The Transcendent One was The Nameless One's mortality (sort of? I assume Ravel's magic helped creating its independant mind) but it was a nice touch and a great conclusion to a wonderfully unique game.

That said, I there's a few things I wonder. First of all, the reason TNO seeked Ravel in the first place was to add more time to his life to make up for the horrible choices he had done in the Blood War (and I assume in other places as well)? Is there any indication there's something else..? To be honest, I had preferred if the reason was that he actually was hunted but only his original's mind knew who it was but hey, that's my opinion on it (and I actually hoped for this ever since you entered the tomb trap).

Second, his name...ahh, it's Lost all over again. You get to know a character that isn't only mysterious but interesting and well, probably has done things many people never have. While it is fitting to the story we didn't get to know the original TNO's name I really, really thought that it might be implied somewhere especially after the tomb trap. When you read one of them, Yemeth is named there along with the Dodecahedron. It said "misery bringer..Yemeth." When I read that the first time I had one of those crawling sensations TNO always had.. ;)

Is it possible that the original TNO was Yemeth, that legendary wizard who apparently sought immortality as well. I killed that Night Hag who had his legacy but unfortunately I never found an interaction in which it made any difference..Is that possible? I killed those two baatezu who said they're TNO's former allies after I had given it to them.

About the characters. I enjoyed them all, I loved that the game had such unique characters and so many, it was sometimes as I was one of those geeky aumented reality simulations some hope we will achieve one day. However, Morte probably striked me as the most interesting. I really liked his sarcastic humour and wit which made me believe that before he became that floating skull he was probably dabbling in forbidden magic and what not to be become that. Speaking of him, did one get to know anything about his prior life other than that he was sent to Pillar of Skulls because one of his lies led to someone's death? I had hoped for a specific quest that resolve at least some of it but I'm a sucker for mysterious so in the end it was great as well that it was left alone. I saw on the wiki and somewhere else that he had a longer name than Morte but I never found anything about that in the game. Please shed some light on that subject.

About the planes. While the game was quite large and had a burning focus on the main plot and TNO I had hoped one could have visited more places especially the Limbo plane where Dak'kon came, it would have been great to see that chaos world in actual sense.

If anything I've said or anything that comes to mind that is specific to this game please shed your opinions as well, I'm certainly not only after the facts of the game. ;)

I forgot about the Lady of Pain. I loved the idea that she was like a mystierious, neutral force, Power, deity, God or what have you that didn't really meddle in people's life unless it was absolutely necessary. I enjoyed that little bit she having a struggle with Aoskar, it would have been great if there were some way to see that. :)

It's been ages since I've played this game or the D&D PnP setting, but IIRC Yemeth is not TNO. Yemeth shows up a couple of the books, first as a minor mention in the chaos planes sourcebook then as a crucial plot point in the last adventure book that wrapped up the setting.

It says in some entry in PST that Yemeth lived centuries before well in-game period so is it possible he lived during the time TNO was in the blood war or whereever he was where he was doing his terrible things that brought him on his immortal mission?

I don't understand that part in that tomb he built. Why did it spell out phrases of his name or descriptions like The Nameless One, The Restless One, Mysery Bringer och and last Yemeth?

Speaking of the reason why TNO wanted to be immortal mentioned somewhat by the good incarnation (first one right?) that he had done terrible things, I think I read here somewhere else he was some kind of general in the war and apparently killed and did horrible things. It seems a bit pointless to me, at least as how it connects the story. I always had the impression that he was hunted (before he was immortal too) and/or that he had done things no man have done which goes back to Ravel's idea about a nature of man.

In the end the game seemed to leave a lot of things open for discussion, mystery and interpretion and I like it that way. :)

Talking to the Practical Incarnation while the Paranoid Incarnation is still alive, and asking about the tomb causes the Paranoid Incarnation to interrupt and admit to upgrading the traps on the tomb when he found it, and sabotaging the writings on the walls.

Given the Paranoid Incarnations obsession with all other incarnations destroying his life and his tenuous grasp on reality its more likely he either wrote that list entirely or added a few incorrect names to it by mistake/mad design.

I got Morte to admit to 'thinking' he was responsible for leading the Original Incarnation to his death and this was why he ended up on the Pillar of Skulls. Nothing more specific. The Practical Incarnation refused to tell me if he knew more about the reason, and the option never came up with the others.

I didn't sacrifice Morte to the Pillar this time around, and I'm thinking maybe that's the point he remembers enough to tell you the specifics? He's supposed to be the one that told you to seek out Ravel in the first place, but how that was a lie - etc that lead to him winding up on the pillar I don't know.

I had a full party when visiting the Fortress and so I never saw Morte confront the Transcendent One unfortunately, I would have preferred to see them chat than Nordom.

One of these days I really will have the willpower to play through with Vhailor and Ignus but everytime I replay Planescape, enough time has passed that I end up recruiting the same gang for old times sake.

About the names on the walls that's a possibility but if I recall correctly I remember that some things on those walls made almost no sense and after talking to the Paranoid Incarnation there's a high chance he was the one that wrote all the gibberish, that list about the names...felt more real and actual but cryptic. As a game design I see it's more of an open mystery.

Morte's confession there, I never got that. I don't think I did a through dialogue check in the fortress right before TTO (I had Morte with me then).

About party, I regret not getting Nordom on my team and I should have picked him on my team instead of Vhailor (or Ignus, had Ignus until Vhailor) because he pissed me off. He was a good add to the story but as a character, that whole justice things felt a bit self righteous and I can't stand that altough the game developers did a terrific job balancing him being represented as a shadow of himself and the aspect of justice as a force, kind of like Ignus had become, a living force of fire.

After finishing the game I did some reading and I found a few quotes by Nordom and he seemed to be a very interesting and hilarious character. I like the formal sentences he seems to use all the time. What exactly did he say to TTO? Also, how was he in battle? I had a feeling would I've recruited him arrows would have been an issue but perhaps not since I barely used my gold.

Can you explain why it could not have been Yemeth? It's pretty obvious - or too much obvious maybe - that the designers put that name into the game to serve as a hint.
I think that once TNO could have been Yemeth. It was definitely not his original identity, but it could be one of his many identities. Since he had many of them, it doesn't really matter if he was Yemeth OR he was not.
Though what puzzles me even more what his sin could have been, the one that made him think one lifetime will not be enough for repentance. The magnitude of his sin could have been things like destroying gods, smaller planes, or races.

About Yemeth, I actually wrote he could have been one of TNO's earlier identies so I'm not sure exactly who you're asking that question to. It wasn't his original identity because the Good One at the end says he was the original and that he committed crimes so terrible that either the Paranoid or the Bad One didn't stand up to it at all, even together IIRC.

If it matters or not is invidivual I guess, I was just trying to tie up some minor loose ends in case I missed anything. I'm still annoyed that the wiki present a full name of Morte yet I did never found that in the game but that may have come from the PnP game or whatever PST was created.

His original sin was being some general in the blood war so he probably slaughtered thousands of people but that felt a bit underwhelmed. I think it's more like you said, like genocide of certain types of races or even planes perhaps.

I forgot about this part and I still believe it about his sin:

"It seems a bit pointless to me, at least as how it connects the story. I always had the impression that he was hunted (before he was immortal too) and/or that he had done things no man have done which goes back to Ravel's idea about a nature of man. "

I think I may have mentioned in some other thread but I at least had the idea that Yemeth was the one hunting him for what he did before or during his time as a general in the Blood War. The reason for this was that I had a feeling that Yemeth was more important than the actually showed in the game, only hinting that he was important but not necessarily anymore since he died a long time ago.

Where did you get this information? I know PS:T pretty much, I finished it like five or six times, and though I remember a memory about him being a general, I'm pretty sure there is nothing that states that it was his original sin. Not to mention it's simply totally unrealistic (yeah, probably there is no such word, but I'm from a foreign country).
Yes, I believe it is unrealistic for a Blood War general to feel guilt after ANY kind of sin committed. Planescape is not a world where such romantic things happen, where a mass-murderer (and a high ranking military officer in the Blood War has to be one) simply changes after committing WHATEVER sin and becomes someone who dedicates multiple lifetimes for regretting his sins. It's simply not in their nature, as you may well know.

Oh, wait it's the original sin you wonder about? I don't know if that's what it was called in-game but I meant it as the original part of what he had done but I'm sure he did other things as the Good Incarnation said something like "I committed crimes neither of them could compare to" hinting at whatever the Practical did to survive or the Paranoid to make the voices go away didn't really matter compared to what he had done. What that was, aside from being the general, I don't think it was revealed.

I don't remember if the Good One was the one that went out to seek immortality by Ravel because he needed more time to make up for the things he had committed but if that's true, he must have done something in a short time since he was the original incarnation and probably lacked all the knowledge that either the later incarnations found or TTO for that matter.

As I said earlier, it seems the creator made it intentionally that the game was only suppose to revolve around TNO and his mortality whilst throwing in a lot of other story arcs with open endings or mysteries.

I think that his original sin, much like his original incarnation's name, is supposed to be a mystery so that your imagination can supply whatever's appropriate. Personally I think that his sin was starting the Blood War itself, and that before his intervention the demons and devils left each other alone (or were at least ignorant of each other).
