One who attempts to
divine knowledge (usualy of the future) via
communion with the dead. Originally from
the Greek manteia 'divination' and nekros 'corpse'. Often refers to any magic aspected to death in works of the fantasy genre.
Demonic conjuration and the delving into the secrets of
unlife, the two sides of the skull faced coin. Necromancers, both Hood cursed and deadly.
Why demonic summoning could be considered a branch of
necromancy.
The complete comtrol over
another life force and the threat of destruction held over it is inherantly death aspected.
