The Death Star Salvage Site existed within the Yavin 4 jungles. Following the Rebel Alliance's destruction of the Imperial Death Star close to the moon, fragments of the battle station fell upon the jungle planet.
This particular area was struck by some of that debris. The resulting impact formed a crater, and the surrounding jungle was incinerated. A salvage team, under the leadership of the Selonian Nagem Dr'Lar, established a base inside the crater. They gathered pieces of the massive space station there, intending to sell the recovered materials to the Galactic Empire.
During 1 ABY, a spacer encountered Nagem Dr'Lar at the site, and consented to assist the Selonian with various objectives. Separately, Osae Meilea from the Hutt Expeditionary Force dispatched someone to the salvage site with the mission of halting Dr'Lar's activities.
