This small nation is primarily dominated by the Royal Paladin clan, ruled by the King of Knights, Alfred. It follows a monarchical system of government; the previous ruler's name is unknown. The other prominent force in the United Sanctuary is Oracle Think Tank, a corporation of magically-talented individuals led by the goddess CEO Amaterasu, and guarded by the Oracle Guardians. United Sanctuary is stated to be a holy nation, which combines old traditions with scientific technology. Outside the laws of the United Sanctuary are the Shadow Paladins, founded by Phantom Blaster Dragon in opposition to his ancient enemy the Royal Paladins. The Shadow Paladins are primarily composed of rogue Royal Paladins like Blaster Dark and Darkside Trumpeter, as well as enemies of the state like Skull Witch, Nemain. The Angel Feather Clan also inhabits here, shown to take forms of doctors, nurses, hospitals and many other healing/healer aspects. The clan of Gold Paladin were awakened when the current leading clan, Royal Paladin, were sealed away by an unknown force.
