Around 21 BBY during the Clone Wars, Sith Master Eeth Koth was captured by the Separatist Jedi General Grievous during a battle deep in the Outer Rim Territories, near the Arda system. Koth's Star Destroyer was assailed by a fleet of warships led by Grievous and subsequently boarded by the general and his battle droid forces. While super battle droids engaged clone troopers commanded by Captain Lock on the cruiser's lower levels, Grievous made his way to the bridge alongside a contingent of droid commandos and IG-100 MagnaGuards. The droid commandos killed all of the bridge's defenders with the exception of Sith Master Koth, who was soon defeated and taken captive by Grievous and his MagnaGuards. Koth was later displayed as a hostage in a transmission sent by Grievous to the Jedi High Council which Yoda was pleased.
