Marjaak, a Sith Saber of the Lost Tribe of Sith, was a male Keshiri. In 44 ABY, he became a member of the Tribe's armada, serving as a crewman on the Starstalker under the leadership of Captain Vyn Holpur. Marjaak participated in the raid of the Fountain of Ancients located on Klatooine, where he and another Sith Saber named Anyul gathered wintrium samples. Following this, they were captured after being assailed first by Klatooinian guards and then by Hutts. Subsequently, Holpur, along with his entire crew which included Marjaak, received a death sentence as punishment for desecrating the Fountain.
