The Owls of Dragonspine

Diluc Ragnvindr. A man shrouded in mystery, that piques the interest of the many people of Mondstadt. To a native from elsewhere, he would just seem like any old bartender, but in reality, he has many things he keeps in his heart, that the public will endlessly wonder about. His strange distaste for the Knights of Favonius, his constant brooding demeanour that he suddenly gained one day, and why he keeps so quiet about his father's death. But it may be that the strangest thing about him at all was the fact that, after his father's death, he disappeared. He was gone for years, leaving the nation in search of the truth of what happened to his father. The only one who knows the reasoning to his disappearance, was his childhood best friend, whom he grew up with, Kaeya Alberich. He never told another soul, even on all of his journeys.

Or so he thought.

Old memories resurface when a face from Diluc's past turns up again in what might be the most horrible way possible.
