Alright, here's Vellimir's submission.
Albert Soot – Human Wizard (Mage of the Veil) / 1, age 58.
A former apprentice who long ago traded spellbooks for a broom, Albert has spent decades as a tower sweeper. He’s pleasant, humble, and so ordinary that people often forget he’s there, which, conveniently, is also his greatest magical talent. His arcane bond is a plain iron ring, and his weapon of choice is the same broom he’s been carrying for forty years.
He is a man so magnificently ordinary that he could disappear in plain sight. Not vanish, exactly, just disappear into the foreground. After all, nobody notices a sweeper.
