Trivia

 * The Tome of Judgment is volume VI of a work titled Ignes Fatui: Another Side ("ignes fatui" being Latin for "delusions"; titled Hallucination: Another Side in the Japanese version). Another Side is the name of the music played during Kingdom Hearts Final Mix's secret scene, Deep Dive. Also, a hallucination is also known as an illusion, which is Zexion's attribute and VI is Zexion's rank within the Organization.
 * In 358/2 Days, Zexion can sometimes be seen reading the Tome of Judgment when he is in the lounge.
