General Information
Species None
First Appearance Perplexahedron

The Perplexahedron was an artificial cube-shaped-planet that held the fourth piece of the Map of Infinity. It's known for being a labyrinth planet and leads people into the wrong paths, protecting the Map of Infinity from intruders.


Perplexahedron from inside

Its doors will move to various places, leading people back to where they once started from. Several rooms contain deathtraps. Its doors will also form into a guard to fight people who come through intact, preventing them from moving on to the next room. It was revealed that for them to be called "Guards" they must be guarding something. It was evident that the guards would appear only to protect the Map of Infinity as one got closer to it. The only known organic inhabitant of this planet is the Sentinel.

It was destroyed when a piece of the Map of Infinity was given up by the Sentinel (and thus served its purpose).

Perplexahedron is derived from "perplex", which means to confuse, and "hedron", a geometrical term used in the name of solid figures.


  • The idea of Perplexahedron is derived from the 1997 science fiction movie "Cube". In the movie, a similar structure is created with identical rooms, some with lethal traps, to prevent its inhabitants from escaping. However, the white appearance of the rooms of Perplexahedron is same as those of an older movie "The Cube", released in 1969.
