Floor 13

The thirteenth level of the Dungeon and the deepest any crawler has ever reached in the game's history. Only one human from another world got there, and he died within half an hour. Rage Elementals live here, and the System AI warns it will be a problem for anyone racing to the Eighteenth Floor. The main story has not yet arrived; the page is a stub.
