Last session the party encountered a blue slime in an old well of the keep. They dispatched it with little trouble. On an island in the pool of water they found some gold, a magical shield, and a message cylinder.
Then they moved deeper into the natural cave that intersected the current level of the keep and found a nest of Kruthiks. They managed to avoid most of the pit traps set to contain the Kruthiks and defeated the entire nest. In the nest they found some gold coins and valuable gemstones.
Before this the party rescued Douvian Stall from kidnappers and cleared out a kobold lair. The found evidence that some cult was operating in the keep and needed to be stopped.
