Guardian of Narnia's Night

(this is a peter x reader story)
Everyone in Narnia knew about the prophecy but the prophecy that they knew left out the fact that Aslan's daughter would come out of the shadows and help the 4 children defeat the White Witch. Narnians knew about Aslan's daughter but they have never seen her because she is always in the shadows. Narnians only had guesses of what she looked like in her human form because they knew that she had a lioness form. She was known by many names. Such as, Silent Night , The Princess of Narnia, Shadow Warrior, The Princess of Night, Silent Guardian, and The Princess of Dreams, but most Narnians didn't even know her real name (y/n). She only came out of hiding after 100 years and only showed herself to a couple of people, a fox, a faun, and two beavers this was the day right before the youngest Pevensie came through the wardrobe and it was the day she was ready to fight the winter.
