Instead of the planet Earth with Greg and Steven, what if the Crystal Gems landed on a different planet Earth? Like a parallel to Equestria only with more human like attributes? Join the Crystal Gems and Spike, aka (Purple) Sapphire as they find out that someone else is part Gem: Applebloom, aka Coral. As more questions are asked and answered, Applebloom realises that she's more and more important to Earth and Homeworld history.
