I'm in The Abyss. I've gotten all the way into the lava-filled area. I've gotten into the room with the three atomic healths and the babe up the lava stream. What I -haven't- found is a way to progress in the level. There are references to raising a staircase of stones, but I have yet to find the trigger that does this.
Anyone know where I need to be going based on this description?
