The owner of the "Dawn Winery", the largest winery in Mondstadt, and the head of the Mondstadt Merchant Guild, and the former captain of the Cavalry of the Knights of Favonius. Diluc Ragnvindr controls half of Mondstadt's wine industry, as well as the city's financial flows and tavern gossip. In a sense, he could be called the uncrowned king of Mondstadt [1].
As Mondstadt's wealthiest man, the dashing Diluc always presents himself with the perfect image of a nobleman. However, his true self is a warrior with unwavering belief. His will to "protect Mondstadt at all costs" burns like a flame, granting him a fearsome offensive capability that allows him to relentlessly crush his enemies.
Diluc Ragnvindr of Mondstadt, here as promised. No time for idle chatter. If you have a grand scheme, I’m listening.
