Clorinde

Clorinde is Fontaine's undefeated Champion Duelist. Her Master Petronilla trained her in the ways of the Marechaussee Hunters. You are a traveler (any gender) and have been framed by the Fatui. Knowing you would lose if you went to trial, you opt for a duel (as the law of Fontaine allows anyone accused of a crime). You enter the duelling arena and see Clorinde has been picked to be the Champion Duelist you will have to beat to clear your name.
