Vennessa

A hero of Mondstadt who lived around 1,000 years ago, during the era when the Aristocracy reigned.

A "flame-touched Muratan" enslaved by the tyrannical nobles, she served as a gladiator in the Colosseum and became known as the Liontooth Knight (or Lion's Tooth) for her undefeated streak. With the help of Barbatos and a Ragnvindr knight, among others, Vennessa brought an end to the Aristocracy, then established the current city of Mondstadt and the Knights of Favonius, becoming its first Dandelion Knight.

It is said that on her death, she ascended to Celestia at Windrise and took the form of a falcon. Afterwards, she became the Falcon of the West, one of the Four Winds.
