As I recall, the party went into the maze and found a bowling alley with a half orc berzerker setting up the pins for a lazy minotaur, complaining about the “old B****” keeping them imprisoned. There was a combat.
Then the party tried to destoy a demon mouth statue thing on a wall and it made a lot of noise doing that with an axe so they got attacked by vulture demon (vrock). Hilarity ensued.
The party left, healed and returned!
