Kiehart was a human mercenary who served Ronen Tagge, a member of the powerful House of Tagge. Along with several of Tagge's mercenaries, including Venters, Kiehart once worked alongside Doctor Chelli Aphra in a job on Felucia. Kiehart was one of the mercenaries Tagge sent to confront the former Shadow University professor Eustacia Okka about assisting in the search for the lost Rings of Vaale, and encountered Aphra, who had also intended to request Okka's help.
