Ten years have passed since Rainbow Dash and Spitfire formed their own flight team known as Sonic Dashfire. They've risen up to great fame and hit their peak with young Scootaloo learning from them both. When competition comes about, Dash and Spitfire accept the call and seek out new members to join their team. Sonic Dashfire returns, bigger and better than before.
This is a sequel story to A League of their own, to understand what's going on, go and read that one, including the bonus chapter, as that is technically the first chapter of this story.

Edit: This story has been cancelled, but don't worry, it just didn't turn out the way I felt it should have, I'll return to this with a different story, but I'll leave this one up for the people who enjoy it and would like to ponder the 'what if?'
