The Hellhound In TVD

Long before vampires existed, there was fire. Michael Keller is an immortal anomaly reborn centuries too early, untouched by age or death, wielding a power that bends but never obeys witchcraft. For over a thousand years, he watched history unfold in silence, protecting hidden covens and burning the dead so their souls never lingered too long. In the modern world, his presence shatters the balance. Spells misfire, Originals grow uneasy, doppelgängers draw his attention and ancient magic recognizes him as something undeniable, a force of nature that cannot be stopped. Neither hero nor villain, Michael is a force of restraint in a world of excess. And when fire enters Mystic Falls, fate doesn’t repeat itself. It burns. — Description from novelcodex.org
