ok, I'll bite - I've seen some chatter here and there about Moe still being alive - what is the theory supporting this, didn't Cniur kill him with a chorae? Is the thinking it wasn't really him, but a person within another person sorcery of the Cishaurim?
There is no theory supporting this. Seriously, he's dead. Others might argue otherwise but most of those justification turn on over examining a few choice words (ie, the specific color noted in text when the chorae rolled over him....really?), or relying on deus-ex-machina type secret magics (thus my hyper-meta-super-psuke jab. I've seen suggestions go so far as to say he captured other souls, used them as armor, and the chorae somehow only killed his captured soul armors. Or that he wasn't ever there, or that it was someone that just looked like Moenghus using some kind of soul transplant or skin-spy style replacement stuff using secret psuke-jutsu. These are nor arguments for me)
Other arguments, as H noted, include him still being involved as a post-living entity, such as him ascending into some kind of uber-godhood, transcending death, space, and time to become the Solitary God... or some other such things. While I find these arguments more compelling than the latter, I find it unlikely.
