The Drazen syndicate (alternatively, the Drazen family) was a powerful crime collective of terrorists, infiltrators, and Serbian ex-military mercenaries founded by Serbian war criminal Victor Drazen. Its leaders were Victor and his sons Andre and Alexis Drazen, and they were responsible for the terrorism of Day 1. Motivated by revenge, their goal was to murder or frame-up several Americans who carried out Operation Nightfall, primarily: Senator David Palmer, Jack Bauer, and Robert Ellis.
