After 1 of their number was slain here a
few weeks ago, the brigands gave this room
and the entry corridor a wide berth. A huge
adder, over 12 feet long, dwells here. It
crawled up the rubble spilled into the moat,
and found a nice safe lair where it could hole
up after hunting. In the litter of its nesting
place is a jeweled dagger worth 850 gp.
