Twilight hoped that mare-do-well would teach Rainbow to be humble. Instead, she leaves; just leaves. When they find her later, she lashes out at them. When even the Princess fails to mend fences between them, she along with the rest of the mane 6 attempt drastic action to fix their friendship. An accident during this leaves to Rainbow heavily wounded and with few supplies, in the hostile and merciless lands outside Equestria. Can she rebuild her life? Maybe make something more? Or will she fall, starving, thirsty, wounded, far from home, broken, and abandoned?
Whatever may happen, bear witness.....to Rainbows Lonesome Road.
