Rae pulls the short sword from the dead room manager's head. "Oi," she says. "Th' troll must not have been happy with th' compensation package."

If there's nothing else of interest in the room she finishes her map, puts her journal away, and returns to the room with the troll.  If no one else has done so, she takes the coins from the troll, wary of it, since leo had expressed concern it might get up again.  She keeps a pistol ready and aimed at the beast as she snips the coin purse from...wherever it was wearing it...with a sharp talon.

"Well," Jaskin says, "We seem to have reached a dead end, so we either go aaaaaall the way back to the entrance hall, or look for secret doors, I guess."
Kiki, still in the troll room, leans back on the wall, which pushes open on hinges behind her and she tumbles into a small chamber. "Found one!" she says, lying on her back, arm in the air.

"Perhaps they were renovating to increase the challenge of the dungeon.  A good way to get new business."  Unit approaches the revealed door, having decided to avoid entering the room strewn with entrails.

Rae already has the troll's short sword in her belt.

The stench in the secret room is nearly unbearable, with several bodies piled up, all in various remains of the standard staff uniform.
On the wall is a list of employees, most of the names scratched through. Beside that is a map of the citadel, with several rooms, including all the rooms you've been in to this point, scratched out.
