“[I]t’s a space fantasy, so there’s no Earth, necessarily,” Snyder teased last month. “There’s a community on a planet, a farming planet, and there’s a bunch of bad guys. The mother world’s armies are in the area, and they need to be fed. So they come to the village and ask for the village to feed them, basically, while they’re doing their war in that area of the galaxy. And, of course, they are not kind about asking — and the result will probably be the obliteration of the village. The villagers decide to fight, and so they have to go out into the galaxy and collect some soldiers, warriors to help them.”

Hmmmm a bunch of soldiers from the mother~~land~~planet show up to a remote farming planet and try to take their grains. So the farmers go and recruit some people who opposed the mother~~land~~planet, to help fight.
