"How many more Gems are trapped here?"

That was the question Steven asked Ruby, but was it true? Little did The Crystal Gems know was that there was another Gem held prisoner in the ship by Homeworld, Black Crystal. Just before the ship fell out of space, Black Crystal escaped from his cell and tried to find his way to the bridge and set a course back to Earth so he could make a break for it. But when the ship began shaking after some kind of explosion, he tripped and fell, accidentally activating one of the escape pods and being flung, not to Earth, but across the galaxy.

3 years later, he is now residing in an alternate version of Earth, where everybody had technicolored skin, so he fit in just fine, he is working a stable job to maintain his new home, and he's getting an education at Canterlot High School, luckily, he was able to work on some citizenship papers and other important paperwork to make him appear to be a legit human being. Everything was going great for him.

...Or was it?

Not only does he have to deal with Sunset Shimmer and her cronies, Snips and Snails, but now other Gems are coming out of the woodwork; The Crystal Gems, Homeworlders, and corrupted Gems. With his past quickly catching up with him, can he keep who and what he truly is a secret? And more importantly, what does Sunset want with him anyway?
