Hello, I've been stuck in this part of Underworlds for too long: I'm in Hell I guess and the Mage told me I had to kill three bosses to face the big one. I've killed three big things (bosses I guess) and found a staircase. Down the staircase there is a room with a devil symbol (star) but nothing is there. I've scoured the level and have no where to go. Help!
