Arbra was a densely forested planet that became the headquarters of the Rebel Alliance after the evacuation of Golrath Station, around 3 ABY. Home to the lagomorphic Hoojibs, Arbra was once inhabited by an ancient race who had resided in subterranean cities. After the Battle of Endor, Arbra remained a member of the Alliance of Free Planets, and later the New Republic. The system was overlooked by the Yuuzhan Vong during their invasion, and served as a location to slowly build up military forces.
