[Source] The Vassek system was a remote star system located in the galaxy's Outer Rim Territories that contained the planet Vassek and its three moons, the third of which was home to the fortress of General Grievous, a Kaleesh warlord who led the Separatist Droid Army. During the Clone Wars, a conflict fought between the Galactic Republic and the Confederacy of Independent Systems, a Republic task force traced a frigate stolen by Viceroy Nute Gunray of the Trade Federation to Grievous's fortress on Vassek's thrid moon, but it was forced off-world by Grievous himself.
