A seasoned alchemist with a sharp wit and sharper eyes, Arcturus Thornwell is an eccentric figure clad in a patchwork of stained robes, each splattered with various potions and substances. With a background as a traveling alchemist and apothecary, he is known for his innovative concoctions and bizarre experiments, often involving rare herbs from the Novice Forest or exotic ingredients from the Isle of Truaks. His classroom resembles a chaotic laboratory, filled with bubbling cauldrons, strange creatures in jars, and odd, glowing substances.
