Round 1
The leader looks at Ehldannis suspiciously as he casts his spell. "What you are saying?" he asks. "That is nota ritual prayer!"
He doens't take any definite action though, and Ehldannis' spell takes effect, dropping two priests and two guards near the north slab.
Tullius is the first to leap into action, striking down the other priest at the north slab. (there was no guard next to him.)
Marcus has to step over the sleeping bodies of the priests to reach the nearest guard. Unfortunately they were not caught completely unaware. Their suspicions proved true by the party's attack. Marcus is able to clip him with his sword, but does no significant damage. (how do you describe a critical hit which does only 3 pts?)
Octar launches himself into the leader. He tries to get his mace around in time to use it, but Octar gets inside his defences to fast. His shoulder catches the tall priest in the ribs and sends him screaming into the abyss. Octar, at the edge, can see him fall.
Dhormium sends a shaft of searing light into the one remaining priest, who screams as his black robe is seared open, revealing leather armor underneath.
The startling success of the party's attack sends the rest of the flock into panicked flight. They begin to stream into the hallway where they came, past Brioc and the wolf. The sole exception is the guard facing Marcus, who is too preoccupied with his combat to notice the bigger picture.
