This world, situated within the Atoan system found in the Ghost Nebula, featured expansive tar pits that formed vast, boiling tar oceans. The Atoans, who originated from the adjacent planet called Atoa, dwelled on this world.
Soon after the Galactic Empire's establishment, the Imperials engaged in a significant campaign within the system. Darth Vader and the 501st Legion launched an assault on the planet, under the false impression that they were responsible for the vanishing of Admiral Garoche Tarkin. The truth was that he had switched his allegiance to Lady Saro, the High Priestess of Atoa and a co-ruler of the system.
