Thelonious Lightbourne is a powerful wizard… in his mind. In reality, he’s more of a pencil pusher at the wizarding school than a wand waver, which explains his bookkeeping job.
Thelonious can be seen diligently working in the corner of the bar, always with a full glass of ale, and always telling a tale to anyone who will listen. He’s well studied in the history of Frampton and tales as old as time, but not nearly as current on his wizarding studies (and the constant full glass of ale keeps his wand skills dull).
He understands what Keldore is doing is wrong, but secretly wishes he had done it first…
