Yavin 4

Yavin 4, also known as Yavin, was the jungle-covered fourth moon in orbit around the red gas giant Yavin Prime. Prior to the Galactic Civil War, Yavin was first a secret rendezvous point for members of the Axis Network and later home to the Massassi Group, one of many disparate rebel cells fighting against the Galactic Empire. Sometime before 2 BBY, the headquarters of the Alliance to Restore the Republic, was established on the moon, becoming fully equipped to wage war by 1 BBY. Following a major battle that took place around Yavin, the Alliance went on the run, and eventually relocated its headquarters to Hoth.

During the New Republic Era, Wetyin's Colony was the main settlement on the moon, and the Dameron family was settled there. Due to New Republic demilitarization, the Civilian Defense Force was founded to defend the moon. The Defense Force, along with the New Republic Security Bureau, was later involved in an altercation with the Spice Runners of Kijimi after they crash-landed on the moon and escaped.
