An alternative ending to the season 5 finale.

Starlight Glimmer destroys the time scroll that allows Twilight to return to Cloudsdale. With the sonic rainboom stopped, her plan has succeeded, and this time, Twilight can't come back to try and stop her again. She thinks it's over, but when Twilight pulls her into the present, Starlight finally sees what her actions have done.

Only a small number of bat ponies remained in Equestria after the disaster of Nightmare Moon. The majority fled, not trusting the nation after being betrayed by their own Princess. But with Luna's thousand year exile having come to a close, it is time for them to rejoin the fold, and no pony is better suited for negotiating that task than the Princess of Friendship herself.

However, when the captain of your escort is Indigo Zap, who suffers from a severe case of Lust At First Sight, and has an ego to put Rainbow Dash's to shame, things get a little more complicated than merely healing millennium-long tensions.
