Echo of the Infinite
She didn't know how, but when Echo was told she would have to convince a young boy to leave his dream world, a place where anything he wishes can exist, she didn't know if she could. But, per her transgressions on the Peddler's contract, she has no choice if she wishes to complete her existence. As broken as flawed as she is, maybe she can help someone else who appears just as broken.
Between a witch, a wizard, a dream, and an echo, maybe there is a story worth telling.
