Atorra, a planet, resided in the Atorra system. Its location was in the Back Reach region of the Gordian Reach sector, specifically the Trans-Hydian segment of the Outer Rim Territories. The Ardan Cross hyperlane linked this planet to both the Troos and Chenowei systems.
Eventually, individuals of the sentient B'trillan species migrated to Atorra, establishing a thinly populated agricultural colony. However, by 43 ABY, the colony had been devastated by drought that persisted for many decades. At that time, rumors circulated about ancient combat that led to alien starships crashing within Atorra's badlands.
The reference book The Essential Atlas, released in 2009, introduced Atorra. Jason Fry and Daniel Wallace were the authors, and they situated the planet in grid location Q-5.
