As the battle in Episode 6:A War of Wardens seems to have ended, inside the memory of the Storm Warden, in the entrance of the Cathedral the party looks and sees Lord Arrabann. He seemed to conjure dozens of what is described as little brains with feet, or spiders attached to brains to do his bidding. As The Wardens stand in the entrance to the Cathedral, the Intellect Devourers crawl on each of the Wardens and cover them. It's described as feeling like being covered in spiders with brains on them. The Intellect Devourers then begin pulsing on their faces and heads. The group, as the Wardens, then feels everything they were go away and they pass out.... everything goes white.
