Black Transmutation

The transmutation of the forbidden components such as the blood in our veins and the very air we breathe is only practised by the depraved, the heartless and the desprate. It is known only by a select few and your average mage is only likely to hear its name in whispers and hushed tones, Black Transmutation. This sect of transmutation magic was devised deep inside the depths of Harrow Mire as a tool for their intelligence operatives to make use of but its practices have been leaked to the wider magical community. Alarento Academy of the Arcane took the initiative to ban its teaching from their classrooms, revoking the arcane licence of anyone caught practising it. If you are brave enough or mad enough to attempt this practice then you may end up paying a heavy price, if you aren't caught and nulled before that happens.
