The omnicrux is what the Befores used as the term to describe the "essence of Grellis". It is a spiritual energy that was said to permeate everything created by the primordial stone god. It was imbued with all his creations. Of all the races, the Inar possessed this energy to the highest degree, being directly created by Grellis, although the Cauthrians also had it to a degree, being interbred with humans. The rest of the races had it to a significantly less degree.
