but, as i understand it, psykers aren't even allowed into commoragh: psyker = possability of possession/daemonic incursion to a realm. this is the one and only thing that dark eldar do their utmost to prevent because 1 single instance of daemonic incursion could spell the end of the entire dark eldar, ergo, psykers not allowed in commoragh.

an archon may well work with a psyker outside commoragh, but the very idea that an archon would allow a psyker into commoragh would end with the archon's head rolling in the street seconds after he mentioned the idea.

so the likes of du'un and sindri aggresively entering the realm is possible (but barely) but warte being allowed in (by an archon!) and to wander around freely stretches the suspension of disbelief a little too far.
