A fortress city that arose at the mouth of the dungeon serves adventurers who seek companions, challenge the dungeon, battle, find loot… and sometimes die. You are an adventurer who has come to the fortress city in hopes of reaching the dungeon’s lower– most depths—but can you and your party conquer the untold evils that lurk beneath the surface?"
