Brother of Leonello Runes, and ex-dean of the School of Runes and Scribing of the College of the Stars. Giulio was particularly enamoured with the idea of teaching based on merit alone and was a vocal supporter of the newly formed college for several years before he handed in his resignation and picked up a more junior position in the Peoples College of Acryn. The only mage in the college at the time, he quickly gain prominence, before forming the department of Applied Magic. The department remains small but active, having only 4 teaching staff in total.

Giulio was taken prisoner by the dragonborn Andrinavana, supposedly to be used as part of an enormous ritual. The official story is he died a hero, using the last of his magic to aid the party of adventurers sent to stop the dragonborn.
