Pesitiin was an Expansion Region gas giant in the Pesitiin system with massive atmospheric storms. It had an abandoned Bosken & Bosken Company mining center which attempted to harvest the planet's gases but failed due to the storms, going bankrupt.
Admiral Gilad Pellaeon attempted to meet with General Garm Bel Iblis in orbit of Pesitiin to sign a peace treaty between the Imperial Remnant and the New Republic. Pellaeon's invitation to Bel Iblis was intercepted by the forces of the traitorous Moff Vilim Disra; Disra also sent Cavrilhu Pirates disguised as Bel Iblis's forces to attack Pellaeon's flagship, the Chimaera. Despite Disra's efforts, Leia Organa Solo was able to learn of Pellaeon's plans, and met the High Admiral at Pesitiin before he left, establishing the preliminary diplomatic groundwork for what eventually became the Pellaeon–Gavrisom Treaty.
