Vassek 3

The third moon of Vassek  was a moon that orbited the planet Vassek, which was located in the Vassek system of the galaxy's Outer Rim Territories, whose landscape was marked by craggy moss-covered canyons filled with dense fog. 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 the fortress of General Grievous, a Kaleesh warlord who led the Separatist Droid Army, but it was forced to retreat off-world by Grievous himself.
