Aberration

An aberration is a member of the race of horrific creatures that were Diem's first attempt at creation. All aberrations come from the universe called X'dalzot, the universe in which Diem trapped the very first aberrations (also called the "Progenitors") soon after their creation.

Power
As the Progenitors were created personally by Diem, their power level is one step weaker than Diem himself, putting them on par with his aspects, The God and The Goddess. This makes them all essentially equivalent to divinities, and much more powerful than simple gods.

Since Diem made many aberrations, he spread his power thinner than he did when creating the aspects, so most of the Progenitors ended up somewhat weaker than the aspects themselves. However, the strongest of the Progenitors, Cthulhu, has gathered his power to become equally matched with The God and The Goddess.
