Neuvillette is an upcoming playable Hydro character in Genshin Impact. He is the Iudex or Chief Justice of Fontaine. Neuvillette was originally mentioned through his quote in Nahida's official introduction. Although the quote gives little information on Neuvillette, it indicates that he is aware of Nahida's active intervention in Sumeru's affairs, which is something unknown to Sumeru's general populace and is relegated to rumors.
