To be honest, since Snake's character is leaving anyway, I think we should just let Ilmlim kill him.  Like Ultha said, it will help get his character more involved in the story, and since Aeriyon is already on his way out, I think priority should be given to the character who's staying, rather than the character who's leaving.<br/><br/>Edit: Besides, this could work out in Elvas' favor, as well.  Accept Ilmlim as a protege, present Aeriyon's head to the Matron, and everybody wins.<br/><br/>Even Antimony, who could have some fun interactions with another half-drow.
