Summary
Following Bellamy's corruption, he flees Gem society and finds himself isolated on a planet far off the starmaps. After a few hundred years, he's found by an eccentric band of traveling gems, most of which he's fairly sure are fugitives, and essentially adopted into this horribly incompatible group of four (now five). Through Bellamy's eyes, he witnesses these gems' stories one by one, finding these ridiculous figures far more tragic than he would have initially expected. Also, he learns what family is. That's a bonus, I guess.

Summary
Pink Diamond has been shattered. The rebellion only seems to be getting worse by the day. Driven to desperate measures, Homeworld employs every loyal gem at its disposal, from a defective Sapphire to a conflicted Jasper.
With the rebel Crystal Gems growing bolder with every attack, Facet 3 of Earth, called "Pangea" by the native organisms, is becoming ever more contested. Goldy is stuck as an advisor for the leader of the small military camp, her Pearl still torn between her past life. Lapis Lazuli, meanwhile, grows increasingly disturbed by the poor regard for the planet she's spent so long terraforming. Brazilian Jasper is left to fend for herself as her squad is taken out, arriving at the camp only for the enemy to strike moments later.A forewarning: I have no proofreader, and have no idea how often I'll be updating this.

Summary

Rebellion was seen as just a myth, or a crazy theory on Homeworld and Gem society as a whole. But what if I told you it happened even before the rebellion took place? The Accident features a Colonization mission gone wrong featuring 3 gems stuck on a deserted Planet not yet ready for colonization, with zero organic life to speak of. They crash, but what now?

Summary
… But being perfect is easy, once you get the hang of it. Carrying on after you fail? That’s the hard part.
This is a story about the first time Peridot fused. Well, this is a story about a lot of things happening to Peridot for the first time, but it's mostly about the fusion thing.
Things got messy afterwards. They - that is, Peridot and Lapis' fusion, which is sort of "they", right? - ran to Pearl for help, and Pearl found she might actually be the one who needs helping, and then everything kind of spiralled from there, but that's not important. Peridot and Lapis fused, and that's a good thing.
It is a good thing, right?

Summary
Diamonds were professionals. They were at the top of the metaphorical pyramid for a reason, and that was because they were perfect, authoritative beings.
-------------
Yellow and Blue Diamond are perfect. They are two gems in the four Diamond authority. So when they fuse, it causes mayhem. Two different Diamonds fusing? Unheard of! So, of course, it is covered up, but when they fuse again, White has no choice but to send them to Pink's old colony.

Keep it Simple, Stupid by ohboyhowdybuckaroo

Summary
Fire Agate preferred to stick mostly to himself.
The mountain bandits he lived with didn't seem to care what he did one way or another unless it was affecting them. That was fine with him. He had more important things to do than worry about a bunch of humans. It's a measured distance. One he maintained pretty easily... most of the time. Then he came along. Some dumbass spinel that demanded he be called "Luffy." And everything just went downhill from there.
Being alone was starting to get A LOT harder with that dirtwad around.
A tale of three gems maybe, sort of finding a place in the world together.

Summary
Peridot was never really into the concept of fusion. Spending time separate together just sounds so much more appealing, honestly!
But in a situation such as this, trapped under a collapsed building with no resources to use besides her friend Bismuth? Well, she supposed she could give it a shot.
