"Being a Noxian means that we always have a choice and that we can become anything we want. Never let anyone tell you that you aren't in control, but don't believe that change is easy, either."
"I didn't know what I wanted, but I knew I wanted it to be my choice."
When Luxanna Crownguard, a teenage Demacian with extraordinary magical power, undertakes a dangerous mission taking her deep into the heart of Noxus, she finds herself face-to-face with one of the city's most dangerous assassins, Katarina Du Couteau. Under the false identity of 'Sinistra', Lux works to infiltrate Noxus's government and discover the intentions of Katarina's father, one of the five generals of the High Command. But it won't be easy. While the Du Couteau's track her every step, a rogue Noxian named Ayer seeks to help Lux in her mission, intent to stop the Du Couteau's at all costs. Reginald, one of many Demacian spies and a childhood friend, will do everything he can to keep Lux safe. With the help of Ayer, Reginald, Cecil (a yordle child with a thirst for adventure), and the rest of Demacia's 'Sprig of Silver' spy network, Lux leads one of the greatest infiltrations in Demacian history.
