Heap Nine was a junker world where scavengers picked at the remnants of a long-dead civilization. In 3 ABY, the Rebel Alliance's 61st Mobile Infantry took a rest stop at the world during its own campaign. Some of the 61st's personnel took dropships to the surface, and a handful of them, including Hazram Namir, Gadren, and Brand, visited a cantina at a settlement there. After Namir failed to flirt with a patron and continued drinking local brew, Gadren helped his comrade from the cantina, and the pair then walked down a street talking of past deployments.
Heap Nine was a terrestrial planet with a Type I atmosphere that was breathable to humans and other alien species.
Heap Nine was once home to a civilization that had long since died out by the time of the Galactic Civil War, having been reduced to garbage piles. During the war, scavengers picked at and traded off what was left of the civilization, and the junker world was overlooked by the Galactic Empire. In 3 ABY, the Rebel Alliance's 61st Mobile Infantry, which had been fighting the Operation Ringbreaker campaign around the Rimma Trade Route, stopped at Heap Nine overnight to give its personnel some rest as suggested by the ex-Imperial Governor Everi Chalis and Chief Medic Von Geiz.
A group of the 61st personnel on shore leave took dropships to the surface of Heap Nine from the unit's CR90 corvette, the Thunderstrike. A handful of them, including the acting Captain Hazram Namir, the ex–bounty hunter Brand, and Gadren, visited an open-air cantina at Heap Nine's settlement, where they drank a local brew. Namir and Brand tried to flirt with two respective patrons. Although Brand was successful and left with her new friend, Namir, who had pretended to be a meteor miner, was rejected by the green-skinned woman he had spoken to. The acting captain had three more drinks before Gadren came and helped him out of the cantina, the pair speaking about whether Namir's failed flirt attempts made him look like a fool.
Namir and Gadren then walked down the settlement's main street and discussed past deployments such as the one on Dreivus. Gadren recounted the 61st's time at Ferrok Pax in order to suggest to Namir that he feared the 61st's past and future sacrifices of its ongoing campaign. Several hours later, the dropships returned the 61st personnel from Heap Nine to the Thunderstrike, and the unit moved onto its next target.
Once home to a civilization which was long dead by the Galactic Civil War, Heap Nine was later inhabited by scavengers, scrap traders, hawkers, and thieves.
Heap Nine had at least one settlement, which included junk and scrap trading shops and a cantina.
Heap Nine appeared in Alexander Freed's 2015 novel Battlefront: Twilight Company.
