Robas, beings native to the galaxy, were brought to the planet Taanab as livestock, accompanying other species when the planet was established as an agricultural center in 2320 BBY. These creatures were discovered within the enclosures of meat processing facilities situated near the temperate regions. The world became particularly famous for its high-quality roba steak. During the time of the First Order-Resistance War, many Zilkin possessed a collection of robas on the planet Kamil.
According to Galaxy Guide 4: Alien Races within Star Wars Legends continuity, the Robas originated from the world of Aralia.
