Belshar Othacuu, found within the Belshar sector, was a Mid Rim celestial object. During the era of the Galactic Civil War, the Galactic Empire established a secret base there for the Commission for the Preservation of the New Order, and a convoy carrying military resources was slated to deliver goods to that location. From 12 ABY to 13 ABY, Belshar Othacuu fell under the jurisdiction of the New Republic.
Residing within the Belshar Othacuu system, Belshar Othacuu was a planet. This system was a component of the Belshar sector, which itself was located in the New Territories region of the Mid Rim. It was situated on the Namadii Corridor hyperlane, providing connectivity to the Ord Varee system and the Glee Anselm system within the adjacent Jalor sector.
Sometime after the Battle of Yavin, during the Galactic Civil War time, the Galactic Empire's Commission for the Preservation of the New Order constructed a clandestine installation on Belshar Othacuu. Bonic Tarracus, an undercover operative for the Rebel Alliance operating from the Core Worlds with the code name "Corewatch," eventually discovered plans for a convoy filled with military supplies destined for the facility, and relayed this information to Alliance High Command.
Later, General Airen Cracken of the Alliance referenced Corewatch's report about the convoy aimed at Belshar Othacuu in a datafile entry about the agent, within a larger document detailing various Rebel agents. From 12 ABY to 13 ABY, Belshar Othacuu was under the control of the New Republic.
Chuck Truett conceived Belshar Othacuu, introducing it in Cracken's Rebel Operatives, a West End Games sourcebook for Star Wars: The Roleplaying Game released in 1994. The reference book The Essential Atlas from 2009 situated the Belshar Othacuu system, and thus the planet itself, in grid square J-7.
