The Lord of Light is a Demigod spirit that cannot access the Ancient World without possessing a Mortal to act as a vessel. Each time the Lord of Light has visited The Ancient World, it has used the body of Stillstanden, an elf, whose physical body has deteriorated noticeably over time due to this extensive use. Stillstanden now wears a black robe and mask to hide his appearance.
The Lord of Light is closely related to Shadow Tome, a magical book which holds great power, though the extent of this power is still unknown. Terth seeks the Tome, and the Lord of Light maintains that the Mortals must hold the Tome to keep it hidden away from the God of Darkness.
Some believe that he is the creator of elves.
