Arthur is the Duke of Rootrun and the master of a mythic cryture known as The Verdant King. He leaves most of the day-to-day management of the town to his court, while he visits the outlying farms, using The Verdant King's power to fertilize their crops with its fairy dust.

Arthur learned conjuring from his mentor, King Noah Stormfischer, who also happens to be the first known conjurer to bind a mythic cryture. Under the king's tutelage, he befriended his fellow students, Lucas Loric and Kasper Starber. Together, the three of them became known as a legendary trio of conjurers, with many fantastic exploits and expeditions to brag about. Chief among them was the hunt for The Verdant King, which ended with Arthur managing to bind the mythic cryture, after a lengthy trek through the wilderness and a vicious battle with the king and its entourage.

Since then, Arthur and his friends have been hard at work, founding Rootrun and building it up into the agricultural powerhouse it is today.
