About half a century ago, a bunch of rich bastards from earth decided to turn the Mare Crisium into a paradise. Through the wonders of science, genetic engineering, cloning and their own superior intellects, they built themselves a utopia. Actually, they built hundreds of little utopias.
And it all went to shit. Crisium these days is the nuttiest place on Luna. We’re talking a few trillion dollars worth of insane, brainwashed, clones and all the whacked-out children they’ve bred since then. Don’t go there unless you’re some combination of heavily armed and insane.
