Shifter: The Unkown Primordial
You probably know of how the universe started. First there was Void, then Void had children, Order and Chaos. Chaos had children, which were the primordials Gaea, Ouranos, Thalassa, Pontus, Nyx, Erebus, Hydros,Chronus, Ourea and Tartarus. Nyx and Erebus had Aether and Hemera.
Guess what, it's not only them. Everyone forgot about him. Everyone forgot about his sacrifice. Everyone forgot about the other universes.
(This is gonna be a fandom crossover story. I don't own any characters that you would be familiar with from other authors)
