An Agamarian beast
This creature was a reptilian type of animal that lived on the planet Agamar. It possessed four legs, a substantial tail, and bony growths extending from a flared crest located at the back of its head. The diet of the Agamarian beast consisted solely of grass and trees.
Moff Nyna Calixte journeyed to Agamar in order to give Emperor Roan Fel a warning about Operation: Thunderstroke, and during this trip, she rode upon one of these creatures.
