I've looked at the accounts of Corcoran since he was 'outed' as a master shedim, and I still can't figure what he's after. Apep Consortium connections and all. Especially since the closure of the Rift.
It's probably just me, but I'd like some additional insight into the motivations for shedim and shades. 'Implacable hatred for metahumanity' loses something after too long.
