Blood Necromancy (concept)
Blood Necromancy is a type of Necromancy associated with Living Magics. Blood Necromancy generally revolves around Vampirism and Thralldom. Blood Necromancers can drain the life force from other humans, animals, or even plants, to strengthen themselves or extend their lives. They can also manipulate the blood in a subject to force them to follow their will. If supplied with a fresh corpse, Blood Necromancers can even control the dead, though only as long as the body still contains blood.
