Wherein the four beta!kids are and always were trolls on Alternia, Sgrub/Sburb does not exist, and Troll Jade Harley is on a quest to keep her friend Aradia from dying. Things will almost certainly get more complicated, but that's a good place to start.
No SGRUB AU, post successful coup, following Eridan Ampora's attempts to make up for being "The Greatest Douchecanoe In The Galaxy" as he finds himself stuck with a bunch of midbloods and fighting to survive such odds as "Oh Shit, It's Drone Season And I Ain't Got Neither A Matesprit Nor A Kismesis". Featuring Karkat "Fix Your Fucking Shit Before I Fix It For You" Vantas reprising his role of the scariest motherfucker this side of the galaxy. Also gills, piercings, and piercings in gills. Also, also sex.
