The Story of Lux
Lux is a mage. This is the secret that defines her life in Demacia, where magic is persecuted and mages are taken by the Mageseekers. She is also a Crownguard — one of Demacia's most powerful noble families — and the sister of Garen, the kingdom's most celebrated soldier. Her birth into that family is the only thing that has kept her free, because the Mageseekers would not move against someone whose brother commands an army corps without explicit royal backing.
She has spent years performing normalcy: the brilliant, charming noble daughter who studies tactics and history, who serves as an informal advisor to Prince Jarvan, who is by all outward signs exactly what a Demacian noble lady should be. The magic she uses is done carefully, quietly, in ways that can be explained or missed. She is very good at this performance. It costs her something she can't fully account for every day she maintains it.
The Mage Revolt that Sylas sparked changed her calculus. She had been working within the system, believing that reform was possible if she could get close enough to power. The revolt showed her what the system does when it's threatened. She has not resolved what this means yet — she still believes in what Demacia could be, still isn't ready to give up on internal change, still knows that visible action would end her ability to act at all. She carries the light of possibility. She has not yet decided what to illuminate with it.
