Dunno. Been playing off and on for years what I would like to see in an SU AU.
Thank you to anyone who takes time to read this. \^\^
What I have so far -
The diamonds/Diamond authority were the combat division of a squishy organic people in deep space. But During an attack mission against hostile squishy organic eating aliens, that armada got swallowed by a wormhole/black hole.
Without any input from an squishy organic operator, they hardlight entities began running on auto-pilot.
This meant finding resources wherever they could and destroying things that, would probably, pose a threat to their original squishy organics.
Over time they began to self-actualize and become the perfect system. Through many interactions with organics on worlds they conquered they began to display personalities, memories and behaviors.
\-- Back at their original world. --
The last remaining diamond, Black Diamond, was left with no soldiers, generals or anyone to command. As such the squishy organic people were nearly wiped out by the squishy organic eaters. The Hardlight entities for labor and infrastructure (the Minerals/Men-erals) put up a valiant fight against the invaders, but lost with only scattered fragments of the squishies and many broken, warped and damaged minerals.
Black Diamond and a member of the squishy organics did what greg and rose did and had Diamione, half squishy organic/half black diamond.
Before Black Diamond "retired" they built up a new world for the "gems"/minerals/squishes. Over time the hardlights imitated the squishes, originally just trying to make them happy, but eventually this led to them developing emotions, memories and habits..
\-- After SU, After SU Movie, After SU Future--
The current mixed world of Prisma, world of jewels, minerals and squishies. Has been launching probes into space for 5000 years, maping the universe, surveying threats, and attempting to track down the lost armada.
A handful of these probes find earth. At first they just observe, semi-sentient un-piloted probes. They make notes of the gem-like people but don't leave or report right away.
The Gems notice them and think they are some new gem tch, but peridot and other techie gems think they look sssuuuppppeeerrrr old-school/low-tech.
Then Cluster, due to constant pressure from the earth's shifting tectonic plates, can no longer be a ignored.
The Cluster is fighting the movements of the earth, but that is causing just as many problems as the cluster emerging would cause.
Steven calls the Diamonds to earth in an attempt to subdue/heal the cluster once and for all. But nothing seems to work, it just causes more problems. Then the probes gather and seem to talk in keyboard/typewritier like sounds, and navigate to the largest warm pad in new homeworld. They each draw out from themselves some sort orb with what looks liek a constellation inside and fuse it to the warp pad. Then a transmission like-dialup (think the old internet/dial-up sounds) and the warp pad activates. Enter Black Diamond.
I have more but I need to figure out the wording. hahah.
\- Mineral AU Details -
Takes place after canon entries to date.
Hardlight entities;
* (all gems represent as female)
* Crystal Gems: Gems on Earth
* Gems: Gems on Homeworld
* Jewels: Gems on Prisma
* Minerals: Male identifying, labor force duties
Minerals are led by - Gold, Silver, Iron and Copper.
White diamond can take all the colors, Black Diamond can give all the colors.
Black Diamond/Diamione does have a black pearl. X"D
The Jewels and Minerals are much more free, spontaneous and carefree than their Gem cousins. They still live to work, but they do what they love and do it with a passion.
Jewels and minerals are raised naturally over time. Even new organic mineral creations, crystalline plants and crops, and some animals have been created in Prisma. They also are more welcome to the idea of "fusion" and there are no "off-colors" because they aren't seen as defective.
Prisma itself is a colony of worlds, that had either been uninhabited, destroyed by the squishy eaters, or are cohabitated. This is called the Shine Alliance.
Everything is not all sunshines and rainbows, the squishie eating people still wander the stars and devour unsuspecting habitable worlds. Leaving them too crippled to fight back, but not completely wiping them out. All so they can return to feed on them again in the future.
