Dodecahedron

A dodecahedron was a twelve-sided regular polyhedron, with each side made up of a pentagon. On Tigella the dodecahedron was considered by the Deons to be a metaphysical form conjured through beliefs. (DW: Meglos)

A Dodecahedron was used to power the Tigellans city, and according to Meglos that Dodecahedron was stolen. Just before the devastation of the Zolfa-Thurans, there was a war between Tigella and Zolfa-Thura, a Tigellan agent had stolen the Dodecahedron during the activation of The Screens of Zolfa-Thura, which caused a shockwave, distinegrating all organic life on the planet.source needed]
