Sokoban (warehouse keeper in Japanese) is a branch of the dungeon modeled on and named after a game where a character is navigated through a series of levels. The object is to move objects to cover goal squares. In the traditional game, the character must move only in the cardinal directions (north, south, east, and west) and push the objects from behind to move them. A player fails by getting objects stuck or boxing himself/herself in, as objects cannot be pulled, created, or destroyed. Adventurers who die in Sokoban will not leave bones.
