Vitamort is Sage Dubois, daughter of Bastien Dubois, a French scientist, and Lebentod, a forgotten German spirit who wanders aimlessly in the forest of Schwarzwald.
Vitamort appears when people and plants are on the verge of dying, and uses her magic to resurrect them. Occasionally she uses necromancy, but only if it helps the environment or if the organism's misery is too plentiful.
Vitamort is neither good nor evil. She is the one who controls what creatures perish and what creatures are born. Vitamort is not visible to mortals. Her archenemy is Mentia, who controls the mind. Human brains are very much against the idea that all things must come to an end, but it is the truth.
