The antediluvian cube is a device carried by Principal Helman. According to Helman, the cube contains "the souls of countless underachievers, as well as several metaphorical puzzles", for which the penalty to solve is far wose than death.

Zack Jackson attempts to solve the cube's puzzle and fails. After this, the cube (and Principal Helman) menace him whenever he is caught in the hall without a pass.
