MoonWingsOfFire
(yes I know the name is similar to Legends: Dragonslayer, but I couldn't think of anything else that would match what the story is about)
Caramel is a scavenger who lived alone for most of her life, but all that changes when she finds a baby RainWing tied up and injured at her doorstep, she decides to take them in, now being shunned by other scavengers, she runs away, deciding to help any little dragons she comes across.
