After the empire collapsed, the planet would continue to thrive as a world of the Honorable Union of Desevro and Tion, eventually becoming part of the Tion Hegemony when the Tion Cluster joined the Galactic Republic.
In the Republic's final years, the Tion Cluster worlds joined the CIS and would later become a part of the Galactic Empire.
