The civilized world shuns those who study this magic, but in the dark corners of the world, there are dark people studying dark knowledge. Blood magic is the practice of sacrificing blood and vitality for power. Not all who study blood magic are evil, but all accept the dark reality of the practice There are some mages who see using their life force to aid others as noble, but there are also those who use the sacrifice of blood to empower themselves beyond those who restrict themselves behind morality. No matter how one views them, or how a Blood Mage views themselves, blood magic is a dangerous power to possess.
