Dark Necromancy (concept)
Dark Necromancy is a type of Necromancy associated with Dead Magics. Dark Necromancy is the control of the ancient dead, generally meaning skeletons or bodies preserved long enough to survive desiccation. Dark Necromancy is normally done through the bonding of souls to the long dead - this is most easily done through the same soul that once belonged to the body, but if need be any will do. Dark Necromancers can command legions of the Undead using their own life force to bond them to service, and the greatest among Dead Necromancers can even achieve Lichdom, a state of eternal life where a Magi bonds their soul to their own body - and then kills themselves. Living forever with full power and sentience.
