Fiction:Essence/Nightmare Energy

Chaos energy is the most primal of all energies, originating from the very dawn of reality. It is stronger than Demonic, Celestial, and other energy, but it cannot been mastered by anyone completely, as harnessing this energy will completely destroy the user. Though, chaos energy can be partially controlled, though this will still have impact on user. The only being that could use chaos energy fully was Asdran'Ar (aka the Imperios), but he was weakened and trapped by Kamik'Shi and Kkia'Sihm.
