Kill Hemma Royde
I have two quests left - Great Elemental Lord & Rescue Lady Nyx. I have restored all four elemental mages (their statues are in Mage Haven). I have the Draconian Staff. I found Hemma Royde in the room beyond Lady Nyx in Last Days Hall. His name bar is green, so the game considers him friendly when I try to attack him with the Draconian Staff. The only option when I try to talk to him is Mindread, which just reduces my health to 10, and he stays green. The nearby door to the teleporter says it's locked until I kill Hemma Royde. What am I missing here?
