Emeralditan is a beast/titantoise-type enemy in Final Fantasy XII. It can be found as a regular enemy in the Nabreus Deadlands, though the party can actually first encounter one in the Nam-Yensa Sandsea, under the name Urutan Eater. The Emeralditans fought at Nabreus have two different versions, though their stats are identical bar their level; the main difference is if they are immune to Sleep or not and what buffs they spawn with.
Being a primal race, the oldest of the long-lived great titantoises. Their existence is referred to only briefly in legend, and in the absence of a verifiable sighting, they were considered to be a myth for centuries.

The oldest chronicles relate the properties of a rare metal called scarletite. In an age when men lived under the watchful guard of the gods, the gods granted them scarletite, for they were favored of their creators. Modern alchemy has to date failed to reproduce this metal, lending credit to the theory that the gods did exist, and are not merely the inventions of a devout imagination. Only by mixing other metals and lowering the purity of this substance may it be worked with modern tools.
