The Unknown

The Unknown is a cosmic entity, whose full power and origin are both not known. It is believed to have existed before time and space, and is capable of unravelling and devouring both. Although it's main essence is imprisoned by the Council of Balance, it's influence stretches far beyond the Multiverse. It is confirmed to have god-like sentience.

The Unknown has been known to manifest as a cloud of mist that is pale as death, but is believed to be able to manifest in any form.
