Arnolde is the first known centaur magician, introduced in Centaur Aisle. His talent is initially portrayed as the ability to generate an aisle of magic around his body while in Mundania, and its discovery when he was ninety years old led to his banishment from Centaur Isle. Despite being banished by his fellow centaurs, he is well regarded by humans, as his talent enabled the rescue of King Trent and Queen Iris from a Mundanian prison. In Golem in the Gears, he reveals he has discovered he can create an aisle of non-magic in Xanth while carrying reverse wood.
