Attack on Korriban

During the early days of their conquest of the galaxy, the Eternal Empire launched an attack on the Sith planet of Korriban. Led by Princes Arcann and Thexan, the Eternal Empire's forces assaulted the Sith homeworld as part of a series of preliminary raids against the eastern galaxy, and were met with resistance under Darth Atroxa of the Sith Empire. Arcann was grievously wounded in the battle, losing an arm and suffering extensive burns to his face. The following day, Arcann&mdash;now equipped with a cybernetic replacement arm&mdash;led a renewed assault, cutting down Darth Atroxa in the process. Despite their victory, the Eternal Empire retreated almost immediately, returning to the Unknown Regions.
