Younger brother of Giulio Runes, Leonello lived most of his life in his brother's shadow. When Giulio resigned his position as dean of the School of Runes and Scribing, Leonello took over from him. Out from under his brother's shadow (and with a bit of a chip on his shoulder), Leonello managed to rise to the position of Demi-Principal. The natural conflict between the two colleges is only exaggerated by Leonello's constant one-upmanship of his brother.
