The question of "How big is Equestria" had always been on Sunny's mind since she was little. Now, with Zipp's ability to fly, she flies up to the stratosphere with her favourite pony. Meanwhile, Pipp is still having a mental breakdown from the loss of her Pippsqueaks.

(Assuming Sunny's wings are a one-time thing.)

Flurry's 4th birthday is coming up, as the Main 6 visits the Crystal Empire to celebrate her birthday. Flurry wonders how she got her name, and if she could change it.

Meanwhile... No, I mean, hundreds of years later, the Main 5 takes a tour of the rebuilt lighthouse.

Pipp didn't make the characters list, because of the 5 character limit.

The last changeling, devoid of love and life, wanders the Everfree Forest alone.

Takes place between G4 and G5. Does not contain any spoilers.
