Blood Mages are an ancient sect of arcane practitioners, specialising in the focus of their abilities through expending their own vitality. Different to sorcerers where the innate magical talent lies in their blood, these wizards are specialists in alchemical abomination and deviation to allow them to manifest their learned abilities.

Most other arcane practitioners consider this practice abhorrent and unnatural, but stories of elder Blood Mages being able to access seemingly unlimited depths of spellpower are certainly a fightening proposition for any that would stand in their way.
