Tol-Kachorn, the capital city located on Yinchorr, served as such for that world. It was during the period of the Galactic Civil War that the Galactic Empire learned that Princess Leia Organa from the Alliance to Restore the Republic was present on Yinchorr. Governor Marcellin Wessel took the Yinchorri Council of Elders as hostages, and in return for their freedom, the Yinchorri tried to hand over Leia Organa as a prisoner to the Empire. Ultimately, the Empire murdered the council, which triggered a rebellion by the Yinchorri. Consequently, the Imperial Military inflicted massive destruction upon the world, including the complete annihilation of Tol-Kachorn.
