Okayyy so. Here's some very messy doodles of a spontaneous au my brain thought of. It's basically a httyd and SU crossover au, except the parralels aren't entirely there for either series, as I had to jumble around some concepts for this to make sense.
But yeah, I won't explain everything (unless prompted to), but so far what I've got is:
Gems work a bit different in this au - they are still solar powered beings made of light who don't need to eat and who can shapeshift, except their base forms are dragons. They can't change their base (dragon) form at all, tho they can choose their appearance when shapeshifted into other creatures.
The homeworld gems are the dragons and the Crystal Gems are mostly actual humans that live among other humans on Berk. Bismuth is there and free, as are probably most of the original CGs, too, since there was no war (so far?)
The exception is Pink - she was a dragon, like all the other Diamonds, but she flew away to escape her miserable household and family situation. She shapeshifted into a human, took on the human name 'Rose', got onto Berk, got together with Greg, boom, Steven's there. Also, she gave up her form, just as in the show.
However, the Diamonds sent gems to go looking for her after it became apparent she wasn't coming back on her own. So dragons started flying all over, appearing on islands they never have reached before, and started terrorising humans in their search. So that's why the two are at odds.
Steven and Connie are childhood friends. However, Steven is sniffed out (literally), kidnapped, and brought to the Diamonds. He's super freaked out, and White's just thinking that he's Rose in hiding. So she forces him to shapeshift. Only to find, his dragon form looks different than Rose's, also, his gem is flipped, so... that's not right. They come to the conclusion that he must be a Rose quartz that somehow got mixed up. The fact that he has Pink's scent must be a coincidence, or maybe their memory is somehow failing them...
Steven manages to escape, despite the struggle of suddenly being in a new body that he can't change out of (since he doesn't have a handle on his powers yet). He desperately makes his way home regardless. It takes a while, having to learn to fly or otherwise traverse the lands and seas, but when he gets there, noone recognises him, and he gets attacked. His powers explode from all the fear that's been festering, and from that incident he becomes known as Berk's most dangerous enemy.
With nowhere to go, he's left to wander in the wilderness, sometimes getting friendly with some other dragons, especially quartzes, but otherwise alone. That is, until a certain human stumbles back into his life...
So yeah. I'm not sure what exactly to do about this au, considering I have very little time to like, start an ask blog or comic or anything, but. We'll see. This is just a very self indulgent thing I wanted to quickly get out ^^
