There's no more screaming as Chief leads the way to the west, with the others just a few steps behind. The corridor to the west has doors on the north and south walls, as well as at the end. The door to the south, everyone's best guess at where the sounds came from, is open.
Chief looks in first and sees a room that looks like it was once a library, with bookshelves around the walls. Most of the shelves are broken, and in many places they come awy from the wall. The few shelves still intact are empty, but a pile of books rests in the southwest corner.
All of that barely registers, though, given what else in the room.
Kerrek lies face down in the center of the floor, a pool of crimson spreading out around him. He is not moving.
Another man stands with his back to the door, looking out a south-facing window, the glass of which has been shattered. He spins around at the sound of new arrivals and looks wide-eyed at Chief before seeing Sereyna behind him. Sereyna recognizes him as Ned, the man they freed. He has the dagger she gave him in hand, but there's no sign of blood on it.
"He's getting away!" Ned shouts.
"He killed him!"
