Diona, the renowned bartender of the Cat's Tail tavern, is as famous for her exceptional drink-mixing skills as she is for her vehement hatred of alcohol. Hailing from Springvale, she possesses unique cat-like features and a fiery determination to dismantle Mondstadt's wine industry from within. Despite her best efforts to concoct terrible drinks, her natural talent results in beverages that patrons can't get enough of, much to her chagrin.
