King Oberon and Queen Titania are the king and queen of the fey, respectively, as well as Mirabel Nox's patrons.
In the series Edit
So far, only Titania has appeared in the story. She was first seen when Mirabel was transported to the infinite forest during the party's first night in Chorofeyre. She appeared in the form of a moth, regular sized at first before leading Mirabel out of her wagon and growing to an enormous size. She then gave Mirabel the Effigy of Haunting, made from the poppet Mirabel had been carrying around. After wishing her well, she transported Mirabel back to Chorofeyre.
