Concept of a Chaos Shard
Chaos Shards are large crystaline objects which are found scattered across many planets in the mortal realm, however the most prominant are Terfall , Ez and _.
They are the fragments of the Chaos Crystal which bond Xecien for over a millenium in the Titan's Palace until the crystal was shattered by Sealiam. Like the crystal, the shards are corrupted to the core by Xecien's touch and wherever they landed they would spread their masters corruption across the face of that world, seeping into the hearts and minds of every mortal or demonkin that stood on it's surface.
