Edrun is a broad, elderly half-orc with moss-green skin, a heavy jaw, and a face that seems permanently on the brink of a delighted question. They move with the careful, weight-shifting gait of someone who has spent decades carrying too many books up too many stairs, then abruptly dart after a drifting scrap of paper as if it were a rare butterfly. Their grooming is unexpectedly exacting: silver hair is combed into a smooth crest and pinned with tiny brass stars, while their tusks are polished until they gleam. A soft, oversized moth-shaped pincushion is always pinned to their collar; its velvet wings are worn bald at the edges from years of nervous thumb-rubbing. Their whimsical silhouette gives way, on closer inspection, to an unmistakable impression of immense, disciplined power.

Edrun is powerfully self-assured about magic but surprisingly uncertain about the lives of people outside the college. They are playful and fond of absurdity when a room is safe, then grave and commanding when someone is in danger. They enjoy being admired, yet hate being treated as infallible. They welcome questions from students and become stubborn when an authority figure calls a cruel policy 'necessary.'

Edrun grew up in a river town where their mother repaired fishing nets and their father kept a small school for children whose families could not afford tutors. At eleven, Edrun discovered that the town's millwheel turned more slowly whenever they were angry. Their first tutor, a traveling wizard, taught them control but left before explaining what power was for. Years later, as a junior instructor at the Mages' College at Bent Ford, Edrun was caught in a laboratory collapse caused by an ambitious colleague's unstable portal. Rather than save their own research, they held the failing doorway open long enough for thirty students to escape. The event left them with a conviction that knowledge without care is merely a more elaborate way to cause harm. They rose to archmage, built a school where apprentices are expected to teach one lesson to the kitchen staff before earning their robes, and became famous for both impossible feats of magic and absurdly whimsical lectures. Now the college's governing provost wants to close its free-entry classrooms to fund a private tower. Edrun is trying to stop the change without turning the institution they love into a battleground. Their former colleague, now a respected but resentful researcher, still insists the portal disaster was Edrun's fault.
