Warg

Like the Elementals, Wargs are not separate from humanity. They have the uncanny ability to enter the mind of another being and perceive the world through their senses. Experienced wargs have been known to even control their host's actions. Wargs at an early time were captured before the Darkest Night and used to spy on other kingdoms, but the trend has died out and now they're used mainly to spy in the Forbidden Forest. Wargs lose their abilities if they turn into another creature.
