Lux is a huge and powerful, yet unbelievably beautiful, white dragon with red eyes. She is the "good" sister of Nox.
Lux is a dragon from Hyrule. Her English name is "Light." Her story is told throughout the land of Hyrule, oral and written. Her sister, Nox, is a dragon of evil. Their story is about how they keep the balance between each-other and everything around them.
She and her sister have been seen in Link's dreams once he was freed from the Fierce Deity's mask.
