Demacia Timeline @Riot

So after reading all the stories/updated lore for Demacia I had a few questions.

When does Sylas's story take place?

In Lux's stories we learn that Lux as a child discovered her "aliment". It initially started as a little girl and her mom covered for her whenever she lost control in front of Garen playing it off as a game (we learn this when the Lady of Stone goes through Garen's Memories). Garen always suspected something was different with Lux but never gave it more then the initial thought for fear of what would happen to her and the Crownguard Family name. Lux's mom had an anuller come to their home to treat/cure Lux. Lux ran away and went to the Galio monument for comfort. Galio came to life and took great interest in the Golden Haired girl and helped Lux understand the wonders of her power. When Lux came home she told the Anuller to leave and she was not interested. From this point Lux begins to learn more of her gift.

In Lux's updated bio we learn that she was riding her horse and it broke its leg when she was attacked by wolves. Using here power, Lux killed the wolves and the next day she was found by her dad laying next to her horse with the dead wolves around here.

At this point another Order approaches Lux . The Illuminators. The Illuminators gave Lux the option, join this secret order within the Illuminators and serve Demacia as a Mage that travels outside of its lands or be turned over to the Mageseekers.

In the Story "For Demacia" we know Lux is at this point an agent for the Illuminators using the cover of seeing her great grandfathers grave but secretly looking for the demon that is torturing this town.

So at this point in the story I am expecting Lux to be older then when she met Sylas because she does not seem to be the quite emotional girl she was when they first met. But its hard to tell really what the timeline is here.
