Kiehart, a mercenary of the human species, was employed by Ronen Tagge, who belonged to the influential House of Tagge. He was part of Tagge's mercenaries, which included Venters, and at one point collaborated with Doctor Chelli Aphra on a mission located on Felucia. Tagge dispatched Kiehart, among other mercenaries, to challenge Eustacia Okka, a one-time professor from the Shadow University, regarding her participation in the quest for the missing Rings of Vaale; during this mission, Kiehart came across Aphra, who also wanted to solicit Okka's aid.
