A vigilante in the city of Detroit. Adrien was originally a human, a former aspiring musician until he was attacked by a vampire a year before the events of this series.  As a result of this attack, Adrien gained vampire-like abilities such as teleportation, enhanced strength, enhanced senes, etc while retaining his humanity, a rare distinction of being a half human and half vampire hybrid.  Now with these gifts, Adrien becomes The Blood Knight to spread fear of his existence to criminals and vampires in the city.Outside his Blood Knight appearance, Adrien can be described as tall (6 ft), slim but slightly muscular, good looking but edgy facial features, shoulder length messy dirty blonde hair, slightly pale skin with yellow-ish/orange eyes.
