Lasan was a planet located at the edge of the galaxy’s Outer Rim Territories near Wild Space and was inhabited by the Lasat species after leaving their homeworld of Lira San. The planet was protected by the Lasan High Honor Guard. During the reign of the Galactic Empire, Imperial forces led by Alexsandr Kallus devastated Lasan and killed most of its population, though many Lasat still remained on Lira San. Stormtrooper TK-421 was stationed on Lasan at one point.
