Diluc Ragnvindr is the owner of Mondstadt’s Dawn Winery, a large manor home to many different imported wines from across Teyvat, inherited from his late father, Crepus Ragnvindr. He has an adoptive brother, Kaeya Alberich, who he dislikes. Diluc is described as aloof, cold, & unaproachable, but underneath, he is a polite, well-tempered gentleman who has a kinder soul inside past the hardened exterior. Also secretly a nighttime vigilante, the “Darknight Hero”. Uses a pyro-infused claymore.
