Vralaa' is of the Fire Caste (hence the Shas in her name) and is the equivalent of a Lieutenant in human armies (hence the 'Ui in her name). She is a T'au, having pale teal skin, red eyes and darker lapis hair. She is a fair bit shorter than average humans, standing at 4'9". She is equipped in a Fire Warrior's standard set: power armor, target-lock module helmet and pulse rifle. She is trained specially to fight Astartes, and thus holds a new T'au-made plasma powersword.
