In 4 ABY, Taym Dren-garen's assigned task from Jabba Desilijic Tiure was to provoke the local Tusken Raiders into attacking nearby Tatooinian settlers, by telling various lies about them and supplying the Tuskens with weapons. The resulting skirmishes between the Tuskens and settlers kept the Tatooine authorities busy, and unable to focus on Jabba the Hutt's dealings.
During the planned execution of Luke Skywalker, Han Solo, and Chewbacca over the Great Pit of Carkoon, Skywalker equipped himself with a lightsaber previously hidden in the Astromech droidR2-D2. He began fighting his way through several of Jabba's henchmen, in an attempt to free his friends and himself from Jabba's control.
After already witnessing several of his fellow henchmen fall by Skywalker's lightsaber, Dren-garen found the opportunity to disable the attacker by shooting his right hand, which at the moment Skywalker held raised above his head, gripping his green bladed weapon.
Taym did not count on the strength and resolve of the Force-powered Jedi Knight, nor did he understand that he had actually shot at Skywalker's cybernetic hand. Skywalker struck out at Taym with his lightsaber, slashing him between his left shoulder and neck.
With a howl of pain, Taym Dren-garen fell backwards onto the deck of Khetanna, and died from his wounds. His body was destroyed a few seconds later when Khetanna exploded.
