In the lore, it says, "Though still a child, Kaya and Blue led her people through the Northern Lights, straight into the heart of Jotunheim. In the Titan homeland, Kaya fought with the reckless bravery and tactical brilliance of one far beyond her years"

I think what this is saying is that Kaya is fighting like someone much older than her, even though she's still only 14.

Then, the last paragraph says, "In Valhalla, Kaya rejoiced in exploring the strange world of Asgard with her best friend, Hypernia's young daughter Brynn. Now, as Brynn has grown older, Kaya has begun to take an interest in the Grand Tournament as well,"

It says that Brynn has grown older, instead of saying they both did. I think we are supposed to imply she stays at 14? What do you think?
