When you get to the area with a big statue with two smaller statues, you'll get a journal entry to the effect that this is where you need to use the Arrow of Extrication. Go up on the platform behind you. Go to the left (facing the shrine-thing) and follow the path. It'll hit a wall and there'll be a little blue button in the wall. Press that and make your way around to the opposite side. You'll need to go through a long system of tunnels to find the other blue button. It's a straight-forward dungeon with the button at the very end. There may be a lich guarding the button.
