Demomooric Blood Ritual Magic

This form of magic originated in Demomoor , and hasn’t been practiced anywhere else. It’s a combination of elements of Shadow Magic  and Necromancy , its primary concept being to take the life energy from one being and transfer it into another. The younger the entity, the more powerful it is, the more powerful the user can become. This power can be harnessed in the form of physical strength, and supernatural abilities. The group that practices this type of magic, Order Of The Temporal Boar , is small in numbers but dedicated. The ritual involves mostly three parties; the subject, the sacrifice, and the order. The subject, first ordained with protection oils to ensure their survival, is placed into a room away from the members of the order, who in the meantime, is preparing the sacrifice. This, oftentimes, involved children as young as two, stolen from the above nation of Storia. The sacrifice is killed, and drained, the limbs dismembered and the flesh often used as armor of ceremonial garbs.
The drained blood is enchanted, and in another following ritual, blood from every order member is drawn. collected, enchanted, and mixed with the blood from the sacrifice.
The subject, having to be chained down in some stances, has sigils drawn into their chest with the ritual blood and is forced to drink the rest. The process of the magic taking over the subjects body is motifyingly painful, which is why they’re chained down most of the time, so they won’t attempt to rip their own skin off to relieve the pain.
