I'm curious to see if there's a hierarchy of some sort in play. We seem to have put own down, and something more powerful than he seemed to be granting his requests for the voidsent he summoned. Ascians were also referred to as shadoweaters or those who have eaten their own shadow on occasion. Perhaps some are human/recently-ex-human, while others are timeless, and others still have that demonic grim reaper visage. However, perhaps some are merely residing in vessels. I'm not sure if it was the beta programming or what, but we do think we saw a shadow under him...

Who knows where it's all heading. I'm really going to take my time with it, I think.
