Grann Desert is a location in Begnion and first appeared in Chapter 15: The Feral Frontier during Fire Emblem: Path of Radiance. Apostle Sanaki sends Ike and the Greil Mercenaries to dispatch a group of outlaws here, later found to be the Laguz Emancipation Army. It is a place filled with buried treasure and is also the location of the battle against Senator Numida and the Disciples of Order in Part 4, Chapter 3: Distortions in Radiant Dawn. Stefan can be recruited in both games in this location.

There are ancient ruins in this desert that were built by the Zunanma, lost ancestors to both the Beorc and Laguz. These ruins now serve as a base for the Laguz Emancipation Army. There is also a hidden village of various Branded, including Stefan, located somewhere in this desert.
