A storm breaks over Fourtower Bridge
Derry gives Wyndham a curious look when he shakes down the corpse of the spider, considers saying something, and then decides not to.
He then gives the dead kobold a curious look and says, "Strange that it had been out wandering alone."
Addressing the outfit, he warns the members that a mimic lives in the next room, disguising itself as a mound of treasure. First, they would try to sleep it, he says, looking at Valerian.
"If that fails, we will set ablaze the area in front of the door and attack from range."
OOC
(1) Party surrounds the two squares outside the door.
(2) Derry will empties two flasks of oil, one for each square in front of the door.
(3) Derry opens the door.
Presumably, this is where the DM would check for surprise and init so I'll leave off.
