The Voldemork Sovereignty is the area of space ruled by the Voldemork. Whilst they have a matriarchal central government it is very weak and most Voldemork simply do what they want to.
By and large the Voldemork are a peaceful people who do not cause any trouble, but they are not a major power on the galactic stage. Although they do have a well armed military, that is a match for any ship on a one for one basis, their ships are small and agressive and are rarely used for anothying other than boarder defence and patrol.
Chi Se Ching made first contact with them.
