To get this quest, simply talk to Swan, the npc that's standing guard in Mondstadt's main gate entrance. He will then quiz you on the lore of the game.
To the northwest of Mondstadt are some ruins. Legend holds that it was once a city where a tyrant ruled from his tower. It has since been occupied by Dvalin, who shelters himself there. What is the official name now given to these ruins by the Knights of Favonius?
According to knightly etiquette, what is the proper form of address to use when speaking to known individuals encountered within Mondstadt's borders?
"Strange yet respectable traveler."
As I'm sure you are completely aware, the affairs of the Knights of Favonius within the city walls are currently under the management of Ms. Jean. My question, then, is: What is Ms. Jean's official title?
