Stained Glass ~ Peter Pevensie X Reader

She's worked with Aslan for most of her life. He found her when she just shy of eight years of age. It was clear there was something different about her. Something powerful. Asland, the mighty lion, takes her in. He trains her in combat and how to control her gift that not many possess.
All was peaceful until a White Witch takes over Narnia and all its inhabitants. Aslan and Y/N go into hiding until it was the prophecy's time to come true.
But when the Sons and Daughters of Adam and Eve finally arrive, Y/N get's much more than she expected. One of those starting with the name Peter and ending with Pevensie.
