Possibly Mavis, its a female name and it has been shown that Mavis cant still communicate with the world of the living and also the late keeper of Fairy Hills, Hilda showed that deceased wizards can go back to the world of living and perform some magics, so its not impossible that a powerful wizard like Mavis decided to come back for the sake of saving the guild. It would also be befitting if it turned out that Mavis was a fairy in life, would explain a few things. On a random side note, I pray that this new arc is just a time travel arc and we'll get to learn more about Mavis once or if the characters return to their own time.
