The House of Marek was a Human family known to contain at least three Force-sensitive members, beginning with Jedi Knight Kento Marek, and his wife, Mallie Marek. Both Kento and Mallie were raised and trained within the Jedi Order prior to their self-imposed exile during the Clone Wars. Through the two the Jedi, the family produced Galen Marek, one of the most powerful Force-wielders in galactic history. Unlike his parents, however, Galen served as an unofficial member of the Sith Order. Under the codename Starkiller, he served as the secret apprentice of the Sith Lord Darth Vader until his redemption and death in the year 2 BBY. As the last scion of the House of Marek, Galen's passing brought an end to the Marek bloodline. The most visible sign of the family's enduring legacy was its personal crest, which became the official emblem of the Alliance to Restore the Republic. The crest also served as the official symbol of the Alliance's successor states, including the Alliance of Free Planets and the Second Galactic Republic. The crest also symbolized the New Jedi Order. A variation of the crest was also used as the emblem of the Galactic Federation of Free Alliances.
However, the family would live on in a sense through a variety of clones that were engineered within the Timira City Cloning Facility of the planet Kamino. Utilizing Galen Marek's corpse as a genetic template, Darth Vader painstakingly endeavored to create a more powerful version of his late disciple. Out of the numerous genetic failures, including a rogue clone who escaped from Kamino, a single perfect clone emerged and succeeded in accomplishing what all of his precursors had failed at—purging himself of the influence of Galen Marek's memories.
