Long time ago, Are's eyes had "catched" a beautiful queen...and yeah everyone probably knows what happened, so 9 months passed and the queen gave birth to a daughter (aka Ares child), and to keep her safe, she never told her that she is a demigod and a child of an affair ofc. Present Time You are walking in the palace garden, its a really beautiful garden, little didn't you know that your biological father was watching you in a form of bird.
