@RhineQueenXD I know that feeling.
Anyways I would allow anyone to play whichever origin they wanted of course it's just that it should center around one group I think otherwise it'll get confusing jumping between the sides. So if it were Homeworld centric the Crystal Gems would serve as the antagonists rather than vice versa.
And I like the idea of starting before the rebellion as well.
This RP will be a little less light hearted than the show for obvious reasons but yeah I definitely don't want it to be too dark.
And thank you so much! I'd be glad to have a Co-GM because I have no idea what I'm doing. I'd ask my sister but a) She's in the hospital right now and b) She's already GMing a bunch of things outside of here so I doubt she would. XD
