Kessurians were a humanoid sentient species. They had typically red skin, elongated and pointed ears, and hornlike montrals above their ears which aided them in spacial awareness to their surroundings. Their hair was typically brown. They also had rounded nubs above their eyes and below their montrals. The skin on their ears, montrals, cheeks and foreheads was mottled with lighter spots than the rest of their skin.

Kessurians had four limbs, two arms and two legs, and five-fingered hands. The species had at least two sexes: male and female. Male Kessurians could grow facial hair. Some members of the species possessed Force sensitivity.

The Kessurian species possessed a monarchy, with the second in line to the throne given the title of thilas.
