The Hill of Despair is the location of the final battle of Final Fantasy IX, where Necron is fought. The party reaches it after battling Trance Kuja. The exact nature of the Hill of Despair is never explained, but it may be a kind of Purgatorial plane.
After fighting and getting blasted by Kuja's Ultima spell, Zidane wakes up to find himself with his friends in the Hill of Despair, where Necron, a deity whose sole purpose is to destroy all life, reveals his intentions. The battle ends in Necron's supposed defeat. After the battle, the heroes are transported to the area outside of the Iifa Tree by Kuja.
- Necron (Final Boss)
The Hill of Despair returns as the BMS for "The Final Battle" from both Final Fantasy IX and Final Fantasy X.
- The concept art for the Hill of Despair shows the party battling Hades instead of Necron. That is because Hades was originally planned to be the final boss of Final Fantasy IX, but was changed to an optional boss later in development.
- The boss Hades, appearing in this instance with an eye within his sword and numerous prominent eyes peering from his throne, as well as blinking eyes on the interior walls of the colosseum-like arena, it is possible that Hades represented the final culmination of the eye motifs observed throughout the game seen largely displayed on structures of Terran design.
