The Zhell were a people indigenous to Coruscant and the possible ancestors of the Human inhabitants of the world. They consisted of thirteen Nations of Zhell, and their combined military force was known as the Battalions of Zhell. The Zhell eventually recovered and drove the Taungs offworld—the Taungs fled to Roon. Since Coruscant was considered by some to be the homeworld of Humans, several historians hypothesized that the Zhell species may have been the ancestors of the Human race in the galaxy. The name Zhell may have inspired Zhellday in the Galactic Standard Calendar.
