Magea

Mageas, or blood magi as they are called by the Galderings, are Bloodsworn who can manipulate the blood in their own and in others bodies in order to control them or enhance them.

To use blood magic the Mageas smear boiled blood on their skin to form runes, and brand themselves with hot irons which opens them up to the Shadow Plane where they can control their subjects. This link lasts until the brand has completely cooled, and the blood has coagulated.

Becoming a Magea
Parents are allowed to offer their child to the elder Mageas who in turn decide if they are willing to train the child or not. If they are chosen to be trained they are taken from their family and their hard and painful journey begins, they start from a young age to teach them to handle pain as it is it by pain that their controlling works.

Uses
Since the Unification of Galder the controlling of another person for reasons of war is punishable by death, an order signed by the King of Galdegard as a term for the Bloodsworns surrender.

Blood magic in itself is however still lawfully practiced in a number of ways: they aid the Academy in the research of diseases of the blood and sicknesses transmitted through blood, they can aid during an amputation or surgery to reduce the blood loss. Wealthier nobles can hire a Magea during intercourse to manipulate their or their lovers blood flow; some want to feel a greater rush, some want to be controlled, and some want their partner to be completely submissive.
