The crystal in which the original world was created by the dead gods, and everything living within. The dead gods actually poured their very essence, Grim and Radiant energy, into the crystal, leaving them weakened.

The crystal was eventually shattered into innumerable pieces by Peran Tremora, which became the reflected worlds.
