An unassuming fellow, Gerald Tomlin is a soft-spoken, gentle man with a bald head and grey beard, a slight frame and an often cooky, aloof disposition. Yet the observant onlooker can often catch a too-clever twinkle in the old man's blue eyes, and his movements are sometimes far too quick for a seemingly elderly fellow. Wise and powerful, Archmagister Tomlin is the headmaster of the Sorcery Collegium, Aspire branch.

His formal robes are white and lined with decorations of his accomplishments: medals, patches, stoles, and the official magister's hood, all symbols of a high ranking Collegium wizard. A snowy owl is never far from his side, and is often perched on the man's staff. He calls the creature "Macbeth."
