Marrangha is one of the most infamous and reviled forms of Black Magic, used since time immemorial for the creation of new and inevitably twisted forms of life.
The Rhino-Men, Cat People and Mutes are but three of the best known - and most successful - races crafted as the result of its use. Usually, the victims of Marrangha end up as little more than quivering piles of flesh and bone, screaming for their miserable lives to be ended ... if they can scream at all.
This dark art has become even more notorious in recent years owing to its widespread practice among the witches of Dree and by its most unholy practitioner's obsession with it - Zharradan Marr, who even took his name from it. Indeed, Marr has been the most active of all wizards in pursuing the perfection of this foul art, with some saying that he has successfully crafted the perfect warrior-organism, though it is suspected that the Caarth have also become extremely proficient at its use.
