Vennessa was a hero of Mondstadt who lived around 1,000 years ago, during the era when the Mondstadt Aristocracy reigned. A "flame-touched Muratan" enslaved by the tyrannical nobles, she served as a gladiator in the Colosseum and became known as the Lionfang Knight for her undefeated streak. With the help of Barbatos and Ragnvindr, among others, Vennessa brought an end to the Aristocracy, then established the current City of Mondstadt and the Knights of Favonius, becoming its first Grand Master.
