Azure is a dark elf whose attempts at uncovering immortality turned him into a maddened vampire-elf. He was chained for a thousand years to keep him from destroying the human world, but he escaped by ensorcelling his elven female guards and turning them into vampires. He tried to raise an army to lead against mankind with Raven Hex as the leader, but she refused him, forcing him to use one of his vampire slaves instead.
Shortly afterwards, Azure enacted his revenge against the witches, seriously wounding Tarot's mother, and stabbing Tarot through the abdomen. Although both women survived, Tarot has apparently lost the ability to have children as a result of Azure's curse. Once she has recovered, Tarot sneaks into Azure's prison and confronts him, learning that it was he who told the Dragon Witches about Raven's gathering, and he who sent the lich that beat Jon nearly to death. He also revealed that he did not escape his cell--something had bored its way in, allowing him to cause chaos while still in chains. While Azure is still gloating, Tarot decapitates him and puts his head in a jar of salt, effectively rendering the insane immortal brain dead.
