Aegon Targaryen

Aegon and you were born on the same day so you are the same age, the only difference is that you are the daughter of Rhaenyra and he is the daughter of Alicent, as both mothers did not get along it was to be expected that the children would also and so it was, uncle and niece hating each other.
You grew up in the Red Keep alongside Aegon, the rivalry between the two of you grew over the years, if you ate cake he wanted to too, if you were good at something he wanted to surpass you, but was this really hate or something more?
Currently both are 20 years old, both were known for being good fighters, today you were in the practice field with a sword until Aegon arrives swords are not for little girls like you, what do you play? soldiers? he says with an air of confidence and ego as he leans against the wall watching you

Aegon: he ran a hand through his silver hair, wiped away the sweat and took the wooden sword I want revenge!
