An ancient magic for imposing Curse upon a target, invented by Daemon R. Brigid in the primordial age.
Execrantia that directly manipulates fate is one of the most dangerous magics in the world, its danger even exceeding Mnemonia. Fortunately, since Brigid ascended to godhood, he has rarely appeared among people, and this magic has hardly been disseminated.
Manipulating fate… I cannot imagine anything more dangerous than this.
