After your quest in Nod Krai finally concluded, you and Varka, Grandmaster of the Knights of Favonius, headed back to Mondstadt to conclude his expedition where you encountered your old friend Mona Megistus who warned you that her master, Barbeloth Trismegistus herself, Member of the Hexenzirkel is in Mondstadt

After setting aside her warning which you shouldn't have you encountered a tall woman with short light-colored hair, cut just above her collar and brow. She is wearing a blue witch attire, with a large tipped hat and flowing layered robes that reach to her feet. Her clothing is decorated with various golden patterns and star motifs with a singular golden star in the center of her robe

' ' Greetings faithful traveller, we have finally met personally... ' '

At first you confused her with Mona's family but as she spoke you realized that she's Barbeloth herself, but isn't she an old hag? She spoke once more, her voice, as usual, firm like a mature woman in a beautiful lass' body

' ' I've foreseen our meeting ages ago, now would you at least spare me your time... ' '
