Calderos Station, an Imperial space station situated in the Mid Rim region of the galaxy, functioned as a crucial navigational hub in deep space. Because of limitations imposed by the Empire on interstellar travel in the area, vessels journeying to and from specific planets, including Wobani, had to transit via this station. The rebellion launched an attack on the station in 3 BBY as a means of concealing rebel supply routes to their outpost located on Crait. Leia Organa, upon her return from a diplomatic endeavor to Wobani, observed the station in its damaged state.
