Just inside the cave mouth, a few uneven stone steps lead up to a small, dank chamber on the east side of the passage. The cave narrows to a steep fissure at the far end, and is filled with the stench of animals. Savage snarls and the sounds of rattling chains greets your ears where two wolves are chained up just inside the opening. Each wolf's chain leads to an iron rod driven into the base of a stalagmite.
Your darkvision allows you to see further. The main passage from the cave mouth climbs steeply upward, the stream plunging and splashing down it's west side. In the shadows, a side passage leads west across the other side of the stream. This small passage bears left from the main passage, and appears very difficult to climb.
The stream passage continues up beyond another set of uneven steps ahead, bending eastward as it does. A waterfall sounds out from a large cavern somewhere ahead of you. A rickety bridge spans the passage, connecting two tunnels that are 20 feet above the stream.
