Just finished reading Know No Fear again, and once more I am intrigued by Oll.
Now it's clear that he is, or will become Ollanius Pious, but just what is he?
The book seems to suggest he is functionally immortal, and likely capable of either self reincarnation, or perhaps time lordesque regeneration.
It also mentions him being introduced to 'the illuminated' and he clearly has knowledge and wisdom about the ways of the warp.
Could be one the alleged children of the Emperor? Or is he akin to a Daemon of mankind? And just who or what is his God?
