Zeta Energy, known as Sanguine Omnium ("blood of all"), is the cosmic fabric that is an essential part of all magical energies ever discovered, and is what the universe is primarily constructed of. It is also referred to as the 'blood of the universe'.
The cosmic essence has been held to a high, divine, sacred regard with many legends as to its true origins, such as being bled from the Alpha/Author in the dawn of time. There once, and perhaps still, existed special masters and elite mages that worked to harness the energy in its raw, purest, and most potent form, a quest that drove many to insanity or their doom. All known energies within spacetime consist primarily of sanguine omnium. The 6th Zeta, ???, is responsible for preserving the sacred energy so to keep balance in the mortal, physical, metaphysical universe.
