Tol-Kachorn was the main city of Yinchorr. During the Galactic Civil War, the Empire discovered that Princess Leia Organa was on Yinchorr. The Imperial Governor Marcellin Wessel held the Yinchorri Council of Elders hostage: in exchange for the Council's release, the Yinchorri attempted to deliver Leia Organa captive to the Empire. In the end, the Empire slaughtered the Council, and the Yinchorri rebelled. As a result, the Empire devastated the world, destroying Tol-Kachorn.
