Gravitational Pull

(Y/N) and twin brother, Benjamin (L/N), were left for dead in a town ally when they were babies. Fortunately a nice Young married couple took both of them in and taught them Gravity Magic. Everything was good until a dark guild attacker's the town and killed the couple. Years later, (Y/N) and Ben have been going around Fiore taking jobs and stopping dark guilds until they join Fairy Tail. What does life in store for them?
