A non-Aeternal faction of Demons who have become obsessed with the power of Blood Void. They are small by Third Realm Standards, but they make up for it in pure viciousness. Zerouboros lacks a leader of any traditional sort, as they believe only that which exists needs a leader. They do have enough power, however, to have a Gargoyle aide named Regoyle the Endwing. Zerouboros are the traditional enemies of the Angelic Quicksilver Protectorate, and the Aeternals in general have a strong animosity towards Zerouboros. The feeling is mutual.
