Radra IV, situated within the Radra system and located a significant distance away from well-traveled hyperspace lanes near the edge of Imperial territory, was a planet of moderate size exhibiting a diverse range of climatic conditions. Orbiting this planet were a pair of moons. The atmospheric pressure and gravitational pull on Radra IV exceeded slightly those typically experienced by Humans. Due to its substantial reserves of precious metals and various other resources, numerous mining settlements were founded, including the construction of a shared port facility. Upon discovering that the planet also possessed significant quantities of uncommon materials essential for manufacturing various military technologies, the Galactic Empire initiated its own extraction endeavors. Speculation suggests that the Empire used these resources in the construction of hyperspace communication devices.
Although a permanent garrison was never established on the surface, Imperial naval vessels were a constant presence in the system. The Empire asserted authority over the shared port, attempting to undermine the independent mining corporations. It was anticipated that the Empire would soon declare the system off-limits. Deep within its icy, rugged mountain ranges, the Rebel Alliance maintained the Radra Surveillance Post, staffed by both Humans and Mon Calamari under the leadership of Commander Darnak. This outpost was attacked by a unit of snowtroopers, resulting in its complete abandonment and evacuation.
