Crait

Crait was a small salty mineral planet located in a remote sector of the galaxy's Outer Rim Territories. Covered with a layer of white salt over its red soil, the planet once hosted a Rebel Alliance outpost during their early rebellion against the Galactic Empire. Many years later, the uninhabited planet became a haven for Leia Organa's Resistance, which resulted in a battle between the Resistance and the First Order on the planet's surface.
