Uzmeol claims to have been made by the hand of some supremely powerful transcendant being, possibly the Puzzlebox {her}self. Xy claims that xy was made perfect; without any flaws; completely pure. Xy is not boastful about this, but neither is xy shy; to xym, it is simple fact. Many other Messians consider xym obnoxiously arrogant, particularly as it is xyr opinion that pretty much everyone xy meets falls short of the standard of purity and perfection that xy was granted by xyr creator. Xy is not unpleasant about this fact -- it is not, as far as xy is concerned, their fault that they were not handcrafted to a perfect standard -- but xy is completely self-satisfied in a way that rubs most people the wrong way.
Uzmeol claims to be seeking other beings who xy considers perfect, though xy has not found any yet. Xy has no home Warp, though xy travels in all of them, interacting with all Warps, extra-Warp areas, and their inhabitants, with the serene confidence of the completely hubristic. Indeed, xy holds xymself too far aloof to have much of any home at all. Xy maintains a slightly superior reserved politeness with everyone. Xy is also scrupulously honest.
Uzmeol does not appear to be mad, but few choose to take xyr claims seriously. Some think xy's playing an elaborate joke; others, that xy is selectively delusional or blinded by arrogance; others, that, indeed, a great joke is being played on Uzmeol xymself.
Uzmeol is a Mask.
