In this event, the "Ultimate +" tier of battles was removed, replaced with a new 220 difficulty stage, "Apocalypse +". Raids also upgraded from 200 difficulty "Apocalypse" battles to 220 "Apocalypse +". This became the standard format of most Challenge Events for several months.
This event chronicles the entire story of Tidus and Yuna as they journey with their companions to unravel the sorrowful history of Spira. What begins as an awkward meeting in Besaid slowly develops into a bond that transcends the divide between dreams and reality.
"Someday the Dream Will End" was the principal track for this event.
- This is the first event since Window on the Past to have a Mission on the main track of the event, and the first since Flash of Defiance to have more than one Mission within itself.
- This is the first event to omit an extended difficulty dungeon since the feature debuted; in this case, the Ultimate+ dungeon was the one omitted.
- The Memory Crystal III Lode for this event is found in the Ultimate dungeon, the first time it has been moved from Ultimate+ since the feature debuted.
