The Man Made Dungeon Knossos (人造迷宮クノッソス), more commonly known as Knossos (クノッソス), is an artificial underground labyrinth which connects the Dungeon and Daedalus Street, effectively serving as a second entrance to the dungeon.


Knossos' creation began with Daedalus after he was captivated by the original dungeon. His descendants, including Dix, were forced to carry on this project by their blood, which Dix referred to as a "blood curse". Despite being worked on for a thousand years, the man made dungeon only extends as far as the middle floors.
