Rajak Nesir was a male Neimodian who was the commander of the Separatist mega fortress located on Bastion during the Clone Wars. His forces held out against Republic forces for months during the Siege of Bastion, and continued to fight even after the end of the war. However, the Sith Lord Darth Vader eventually arrived and his forces breached the fortress. Vader then went to the command center, where he decapitated Rajak Nesir with his lightsaber.
