House Barong existed as one of the noble houses within the Tapani sector throughout the historical period encompassing the Great Sith War.
In the era of the Great Sith War, the High Lady Brezwalt III of House Mecetti gave the order to her Mecrosa Order Sith assassins to eliminate the head of House Barong, as well as the heads of four other competing houses. Following the assassination of their leader, House Barong was integrated into House Mecetti.
House Barong had ceased to exist by the time of the Imperial Period.
