This cave isn't marked on the map so I'll have to describe. The only road going north from New Athos eventually comes to a rock formation that is almost a circle. A lone road goes inside this formation. The end of the road kind of looks like a question mark. A lone road goes to the east and at it's end is the cave in question. You go in, fight a few ice skeletons and few werebeasts. There's a teleporter at the end. This leads to another cave with two teleporters that lead to closed off portions of the cave. Next to one teleporter are a pair of levers. Has anyone been able to tell what these levers do?
