[X] The Lathe of Heaven
[X] The Fairest
A lack of XP has never been a problem with Rihaku's quests. We have the option to stay under Heartlessness 10 and I think we have the discipline to take it. Reincarnation Planning has, roughly, no appeal to me since I really do not like the conceit of Ulyssian being a "reincarnation" of Odyssial; he is and should be a new person, and the drama comes from grappling with the legacy of his First Age predecessor.
The Lathe of Heaven is, of course, everything Odyssial was working up to. And his name having a terror among gods, fae, demons, and Exalted alike is both amusing and appropriate. We must take this. It is the capstone to Odyssial's entire narrative arc, his monumental attempt, subsumed as it is by thousands upon thousands of years and countless memories, to make up for his failure to his tribe. To his youngest sister. It is a work of incredible hubris and power that must, by its very nature, stand as the ultimate testimony to the promise and terror of the First Age.
The Fairest on the other hand is an interesting plot hook. It'll make Creation slightly less desperate without sacrificing Ulyssian's central opportunity to the continued potency of the Bronze Faction. It finishes his Artifact N/A blade. It mitigates his Heartlessness right as his Infinite Singularity Husk is initiated, lending perhaps the poignant suggestion that, indeed, it would have been worth it after all. I half-suspect that might very well have been behind the Vision of Gold...
