A bit of context: I have just done a massive reread of the OberChron
Last night I had a dream about Dameon and Rushton. I dreamed that Rushton's massive mind cave was going to take the Agyllian oldOnes in. He was going to become the next Agyllian elder.
Meanwhile, Dameon was the Destroyer. Elspeth asked him what the worst thing he had ever done was, and he wouldn't tell her. Then later on when they were in the Sentinel he said "remember when you asked me what the worst thing I have ever done is...it's this" and tried to activate the weaponmachines.
