Xavian

Xavian is the former Immortal of Darkness, known for having taken over Really Cool Land in the past, before being defeated by Ventus and the Artifacts of Wisdom. He has since been replaced by Zais. Unlike other Immortals, Xavian did not choose Zais to replace him, rather Zais developed his powers on his own and forcefully usurped Xavian's position, although the details of the coup are not known. Xavian was imprisoned in another dimension somewhere, and has attempted to excape and reclaim his position at least once, through his vessel, Myrxxan. Defeated by Johnny and Ventus, he remains trapped, but still alive.
