The party enters the keep, and find it crawling with Kobold guards. They manage to fight through several of the kobolds, leaving the evidence of their intent strewn about the dungeon. But, in their lust for treasure, they get distracted and find themselves in a room with Zombies.
D’understanding, the druid, dies in the ensuing fight.
The party retreats back to town. They do manage to find very fine priests vestments and a holy symbol for their trouble.
Back in Ashvin, they meet Gunderson Oakenstaff, the high priest at Ashvin, at the Temple of the Divine Mother. He is watching over the Dwarf Child. He agrees to revive D’understanding in exchange for 500 gold and the holy vestments and symbol. The raising takes 3 days.
After D’understanding is back to life, they head back to Turbo’s Keep, but find it now taken over by wolves, feasting on the entrails of Kobolds. They fight their way deep into the Keep and find Turbo’s lair, but he is not there. Instead of a sealed envelope bearing the seal of the Black Raven’s Guild. The open the envelope but find the parchment is blank. They decide to head back to town to confer with Corvus.
