you are supposed to find a door with two obelisks by itin the Chamber of Fire. I've been through the whole level and the only door I can find is in the Royal Hall. This is my second time through Krokotopia. Is this quest broken now? I did it before.
Keep searching. When you first walk in the door of the Chamber of Fire, you can turn right or left. Turn left. Go toward the Excavation site, but when you have the option to go in the Excavation site or go straight, go straight. Should be at the end of that hall.
