Dungeon of the Mad Mage

The fireball goes off and the party is attacked by a group of Minotaur skeletons and a mage. After eventually knocking him out, the party discover his name is Karstis and he is guarding the way to Dweomercore, the academy for mages that Halaster runs. Karstis also said that if the party let him go, he would give them information about the leader of the bullywogs. After some discussion, they let him go. He turns invisible and flies off, but does tell them the leader is actually a slaad that Halaster summoned. The party sleeps and recovers and tries to decide whether to go down to the next level or head back to the bullywogs.
