Raven checks the door for traps, and is satisfied to find none. She makes short work of the lock, and the door swings open with only a minimal squeak of protest. When she moves up to the ladder on this side and looks up the hole that it extends into, she can see that the rungs of the the ladder stop at a hinged wooden hatch or trapdoor over the top of the hole. She checks the iron rungs, and they seem sturdy enough to support the weight of even Anvuss or Shoot.
