Katrim was a small sub-tropical planet in the Mid Rim. There were few cities on the planet, and much to the dismay of the Republic, it had a Sith on its surface. After the Battle of Katrim, it became war-torn and all of its inhabitants were wiped out when the planet’s power plant blew up. In 100 BBY, it was rediscovered by the Republic and used for weapon testing and starfighter production. It was heavily mined due to the abundance of Galliot. The Empire used the Death Star on it, destroying it.
