Miranda might have been sort of a nice place when it was first terriformed by the Alliance in Firefly and Serenity. But then the government decided to experiment with a chemical that was supposed to curb aggression in the planet’s population. What it did instead was make almost everyone so docile that they all stopped moving and slowly died of, well, all the things you die of when you can’t even make the effort to turn your head slightly. The people who weren’t “almost everyone?” They became horrifying monsters who mutilated themselves and raped, killed, and skinned people across the galaxy for no good reason. Not a fun time for anybody, if you ask us.
