Though the original Ultima Weapon, piloted by Gaius van Baelsar, was destroyed in the decisive battle at the Praetorium, Garlemald has been secretly developing its successor.

At the behest of none other than Gaius Baelsar himself, you cross the scorched battlefield of the Ghimlyt Dark to halt this crimson menace before it lays waste to Eorzea.
