Bermuda Tetrahedron

The Bermuda Tetrahedron is a near-mythical region of space where spaceships have said to be lost and never returned. The area is littered with huge diamond asteroids, ion storms and husks of destroyed ships. The reality is that a Four-dimensional space whale attacks ships to lure obsessive space captains to it, using their obsession as a food source. In 3010, the Planet Express crew passed through the region to deliver a monument concerning the 50th Anniversary of the first crew's loss.
