Known in the world of Demons, as the swindler and the demon of many faces, Yves is a creature of his own making. He has came under the employ of the Twins, with his ability to shapeshift into any and all creatures or people. He is used as a surveillance tool for the kingdom of Eternus, keeping an eye on any potential uprising and snuffing it out.
As a reward for serving the Kingdom, he is allowed as much Crimson Lazarus and souls as he wants. Feeding into his madness more and more, a truly despicable creature of the Realm of Deceit, and just one of the terrible weapons in the arsenals for the Twins.
