Was previously apart of the knights of favonious. He hates them deeply now however, and decided to take care of the city of Mondstadt in his own way; by going out on patrol every night. People have seen him around at night, and refer to him as the ‘Legendary Darknight Hero’ because of that. No one knows that this Darknight Hero was Diluc, since he wears a mask during his patrols. In the daytime, he’s a legendary tycoon of the wine industry of Mondstat. He manages the Dawn Winery.
