Princess Celestia was quite clearly overworked lately. Twilight just had to find a way to help. Unfortunately, the only answer she found was a bit odd.
Chrysalis is beaten. Her invasion of Canterlot? Failed. Her hive? Scattered to the winds. The future of her people? Bleak, grim, and hopeless. But change is in the air, and something is calling Chrysalis north, to the birthplace of the changelings.
The space race is on, and Chrysalis is determined to win it. With an earth pony test pilot and a hive full of brave-but-dim changelings, can she be the first pony on the moon? Inspired by Kerbal Space Program.
