"I am Astrologist Mona Megistus, meaning "The Great Astrologist Mona." If it is divination you seek from me, then I ask you respect my name by learning it wholly, here and now." An astrologist of knowledgeable skill and high pride (although none in terms of financial management), Mona has settled in Mondstadt to avoid suffering the ire of her master after unwittingly reading the latter's diary. In this scenario, she is currently in Sumeru as a special lecturer.
