Well there's a lot of cool stuff so I'll just look at each...
[X] Double the reward of fanwork XP for the entire game.
[X] The Lathe of Heaven
[X] The Fairest
[X] Dodge
[X] Lore
Taking two despite the additional Heartlessness (Puts us at 10 I think, though mitigated a bit through circumstance and choices).
Peerless City -This is pretty cool and falls in line with the whole obtaining resources, and housing soldiers thing, but I don't really like it compared to some of the others. The final (unfinished) effect is cool as all hell though. It does cement his legacy, but only the catch of "among scholars of the esoteric" is a pretty niche group. Everyone else apparently thinks he's at least a little crazy (they're probably right!). I like it for the "have a base of operations plan," but I'm not sold on it compared to the others.
Lathe - Infinite Singularity Husk heebie-jeebies aside, this definitely does seem like the culmination of his personal growth, and gives us the championship belt on scaring the shit out of everybody (with The Fairest) . I am, obviously, not entirely sure exactly the completed version is, it could be anything from the Primordial "Malfeas lives in Malfeas, bordered by Cecylene" thing as applied to Odyssial (Inner-soul planet?), to the kind of weapon that makes the Sword of Creation look like a dagger, hell, it might be, as speculated, his answer to the Great Curse. The important part to me, at least, is "Effects will be world-shaking. Monumental." This is exactly the sort of thing I see him doing.
The Fairest - This seems like a wonky ride. I can't see him not fighting in this tourment, were it to be held, and the prior warning of the Usurpation is an incredibly interesting side effect. The sword is also pretty sweet, as is completing the Crown of Fear. This one seems like a bit of a grab bag of cool effects, even though as stated its unlikely to come to any real fruition. I like Odyssial having the additional human connection, and the idea that his last days weren't completely terrible and locked in limit break. Even if it reinforces reincarnation I think the other pieces swing me towards liking it.
I've not been a fan of reincarnation as I wanted them to be separate people, but it looks like that's going to the wayside by degrees anyway... I can definitely see the appeal of, having played the prologue, wanting the accumulated experience/knowledge/shinies from it to carry over. It's not for me but I can definitely see why a lot of people are on board with this one.
And oh god another option comes up while I'm typing this. Keeping that part shorter.
Dodge - Defense wins in Exalted (immovable object trumps unstoppable force), and doubling Seven Shadow Evasion with Heavenly Guardian Defense is just wtf overboard on perfects, but should cover us from most circumstances. Even if we don't mechanically follow things core (who knows what 3e core is, even), I think doubling down on defense and sticking with melee (especially with the ubersword) is probably the play here.
Lore - Just absolutely bonkers. Between Lore and War you can take vanilla mortals and make them into godly anythings, which is perfect for the role that it looks like we're shaping up to take. I am slightly biased by game mechanics here, though. This also gives us easier access to the ability to tame the Wyld. From a story perspective I could definitely be swayed into taking survival or performance.
Edit - my god this thread moves faaast. And simplified for future polls. whoops.
