The Odyne cabin is made of a dark, rough stone. A cabin on the smaller side, it puzzles other campers, as the way to get into the cabin isn't clear, as three doors are situtated at the front of the cabin, and they seem to never be used by the Odyne campers. The actual entrance is elsewhere, but the other campers have no knowledge of this. If another demigod was not clearly invited into the cabin, they will begin to experience joint pain, which will continuously grow until their bones liquify unless they immediatly leave.[1]
