Sídi, a frigid and gray celestial body, existed within the expanse of the Outer Rim Territories, classified as a planetoid. The only inhabitants able to flourish on this world were humans along with ash-beetles. This planet was home to an ancient communications tower in addition to Rank and Leera's inn throughout the time of the Clone Wars. It was said that Sídi emanated a scent reminiscent of decaying eggs when winds originated from the east.
E. Anne Convery's short story "Bug", which was published in the anthology The Clone Wars: Stories of Light and Dark, featured Sídi; the story came out in 2020.
