Alsakan was a planet in the Core Worlds that served as the homeworld for the people of the Alsakan Union. Before the foundation of the Galactic Republic, the Alsakans decided that no one save for the Alsakan Council of Colonists and the Alsakan Vicar, the leader of the Union, would ever step onto the planet due to religious reasons. Therefore, the orbiting city of Xenvaer was constructed for the Alsakan people to live on.
