The Kraatar Liberation Corps (KLC) grew out of the animosity which some Humans felt towards the Vrusk on the planet Kraatar. Thirty years ago a group of humans founded KLC, a secret organization dedicated to "freeing" Kraatar from vrusk domination by direct action, including bomb attacks and sabotage directed against the vrusk. The KLC believes that once humans have taken control of all planetary and system-wide governments, the UPF, and all mega-corps, then the Frontier is assured of peace. The KLC is a prime target for Star Law investigations.
