Hhallas is notable as being the homeworld of Ralgha nar Hhallas, a former Kilrathi lord who defected to the Terran Confederation in 2655. During the Terran-Kilrathi War, Hhallas was attacked in a Terran raid that left many, including Ralgha's entire family dead.
Hhallas was also the site of one of the Kilrathi Battle Command HQs, where Crown Prince Thrakhath nar Kiranka was stationed in 2667 before being granted permission to personally wage war on the Terrans.
