Lau was an inhabited planet in the galaxy. After Omega and Crosshair fled Imperial facility on Wayland, they ended up on Lau before they managed to steal and ship and leave the planet.
Lau was a largely desolate planet with a cold and windy climate and a landscape featuring jagged cliffs and plains. During the Imperial Era, it maintained an Imperial presence, with TK stormtroopers patrolling the streets of the main settlement.
Around 18 BBY, the clones Omega and Crosshair crash-landed there while fleeing the Advanced Science Division on Wayland. A skirmish on Lau occurred after Imperial Captain Mann attempted to capture Omega and Crosshair, albeit unsuccessfully. The pair managed to steal a ship and leave the planet, eventually reuniting with their squad.
