Ashash, a waterworld, resided within the Ashash system. This system was situated in the Zarracina sector, which itself was located in the Trailing Sectors area of the Expansion Region. A species of creature inhabited this home, and these beings possessed the ability to exude a dangerous gas from their bodies. This characteristic linked them to the stinkfish found on Sedri, a planet in the Outer Rim Territories.
The roleplaying game, Battle for the Golden Sun, released in 1988, featured Ashash. Douglas Kaufman was the author, and West End Games published it for use with Star Wars: The Roleplaying Game. The StarWars.com Online Companion, supplementing the 2009 reference book The Essential Atlas, specified that the Ashash system, and consequently Ashash, was located in grid square N-14.
