The X-Istence was a realm where both Mutants and Atlanteans lived after the Catalyst tried to wipe out all mutants on Earth. After settling down, a team of mutants called X-Command were created to serve and protect the realm. Overtime, the Atlanteans became restless in the fact that their people were dying, with the X-Ential seemingly choosing to ignore their pleas for help. To this end, the Atlanteans kidnapped the X-Ential. As the X-Ential was the being who held the X-Istence together, as soon as he disappeared the X-Istence began to disappear. In an attempt to restore the X-Istence, Major X and M'koy travelled to Earth-616 to find a young X-Ential.
