The Caeus Acritas answer only to their kingdom's leader. They are known to travel in pairs or groups of four and share a worldwide reputation for being ruthless. Some kingdoms use their officers to spy on other powers, or track certain people down. They have a so-called streak of perfection, which entails that they don't fail any job given or allow any lawbreaker to go unpunished. They are only ever seen out and about in the night. The mask they wear is made of a morphing fabric woven from special thread that is more often seen as a hood than the mask for practicality's sake.
