The search for the Treasurebeast Orbs scattered across Caldina leads Hugo and AR-I-CA to the great city of Cortana. This cosmopolitan center of commerce is no doubt a jewel of the desert, but few things in this city have as much value as the Orb said to have arrived here—one said to bestow the coveted power of immortality. With such rumors spreading far and wide, it would be foolish to think that Hugo and AR-I-CA would be the only ones in pursuit of this boon.

A knight of ice, a soaring songstress, a bloodstained child, and a Master of death converge upon the poisoned oasis, heralding the coming of a brand new possibility.
