It would have to be some sort of warp entity, apparently there are spirits as well (i think). How about this, the invasion of the Serathi causes huge outrage amongst the gods of the Milky Way, none more so then Khaine, whose hatread for the invaders is greater than that of Chaos (i know it doesn't make sense but this khaine we r talking about he doesn't give a fuck about anything really) and as a result he signs a pact with the dark gods and using an incredible amount of psychic force and eldar souls Khaine could be turned into this so called symibiote. This could also be the final event to forces the Eldar and Imperium to work together.
