Alucinor

Alucinor is the world in which the Ultima X:Odessey MMORPG would have taken place, had the game not been cancelled by EA.

It was a world within the Avatar's mind, where the hero and the Guardian, now fused into one being, fought for control.

Trivia

 * "Alucinor" roughly translates from Latin to something like "Wandering in the mind."
