This looks like an interesting concept! Kinda like SCP or something :P I'll be keeping my eye on this, see what develops :) 

EDIT: An idea for a potential character would basically be doing what the 2008 version of Day The Earth Stood Still did, make an alien who adopts a human body and remains undercover assisting SIN in dealing with other supernatural/extraterrestrial threats. Still debating whether I'd give him technopathic abilities or not.
