Living up to the name; lord of darkness, he is pure covetousness. He hones his power, unites with the devil, and seals himself in enchanted armor. This aspired lord of darkness loses all sense of self; even if he ends up as a beast of war, so be it.
People who work magic are called by several names in fantasy works, and the terminology differs widely from one fantasy world to another. In Dungeons and Dragons, warlocks are distinguished from wizards as creating forbidden "pacts" with powerful creatures to harnessing their innate magical gifts. In Witch World, a man who anomalously showed the same abilities as a witch was termed a warlock. The term "warlock" is sometimes used to indicate a male witch in fiction. However, either term may be used in a unisex manner, in which case there will be members of both sexes bearing that title. If both terms are used in the same setting, this can indicate a gender-based title for practitioners of identical magic, such as in Harry Potter, or it can indicate that the two sexes practice different types of magic, as in Discworld.
