The Atrivis Resistance Group was the alliance between the Fest Resistance Group and the survivors of the Mantooine Liberators to rebel against the Galactic Empire. It pre-dated the creation of the Alliance to Restore the Republic, but shortly after the formation of the latter, Mon Mothma convinced the Atrivis Resistance Group to merge into the Rebellion as the Atrivis Sector Force.
