D'krn served as a commander for the Galactic Empire during the era of the Galactic Civil War.
In the year 1 ABY, Commander D'krn found himself stationed within the Imperial capital city of Tatooine, specifically Bestine. While stationed there, he gave a spacer an assignment: to acquire a blood sample from the Death Watch Overlord, the leader of the Death Watch located on the forest moon of Endor. Upon the spacer questioning the need for the blood, D'krn explained it could serve as a prime clone source for creating a newer and superior generation of stormtroopers.
The spacer accepted the mission and sought assistance from Boba Fett to gain entry into the Death Watch bunker. After successfully entering the bunker, the spacer, along with a group of allies, eliminated Viba and subsequently delivered the requested blood sample back to D'krn.
Commander D'krn is a Non-Player Character featured in the MMORPG Star Wars Galaxies. Within the game, players have the opportunity to receive a quest from him, tasking them with a mission to the Death Watch Bunker on Endor. Although it is technically possible to complete the quest independently, the game's design suggests that it is more advantageous to enlist the help of other players. This article operates under the assumption that the spacer working for D'krn killed Teti Viba with the aid of others.
