Takes place in the Sombra-Verse
The war with Sombra is finally done. The ponies have won.
The combatants are invited to a big party. It's basically just a distraction from the heartache the war left. Of course, Pinkie Pie, Maud Pie, and Rainbow Dash all go to it. After all, the three of them are three fast friends who really helped the ponies destroy Sombra.
Both Pinkie Pie and Rainbow are now in relationships. Pinkie Pie even has two daughters.
At the party ponies suddenly start to share war stories and then Maud Pie shares one of her own stories.
Great story, Maud stays in character the whole way through and i actually laughed at the rainbow rocks joke.
