Lux is the ultimate White Magic spell. It was placed in the Great Tree Roots by Queen Arbor as a seal to imprison the demon, Belphegor. Years later Torte came to Arbor searching for Lux and opened the chest holding it; in the process, Torte broke the seal that trapped Belphegor and set him free. After the Heroes of Light defeat Belphegor, Queen Arbor gives them the Lux spell.
