Miranda

Serenity/Firefly fans will recognize the name instantly, which is why I used it for the title. Miranda in that science fiction universe created by Joss Whedon

"is a planet located in the Burnham Quadrant, on the very edge of the 'verse. At one time, it possessed an infrastructure as large and as thriving as anything to be found on a central planet. However, Miranda also apparently had a good deal of civil unrest, since the Alliance government decided to use the planet as a large-scale testbed for a chemical known as 'The Pax' which was intended to 'calm the population and weed out aggression.' For the vast majority of Miranda's unfortunate inhabitants, the Pax worked only too well, and millions of people 'stopped fighting...and then they stopped doing everything else.' Including staying alive.

For the few survivors, the consequences were even more horrific; they suffered a reaction to the Pax which was exactly opposite to the one intended-they became raging, homicidal maniacs who engaged in cannibalism, self-mutilation, and torture...in other words, Reavers.

After this, Miranda became a forgotten, inaccessible ghost planet until the secret of what happened there was accidentally gleaned from the minds of key Alliance Parliament members by a disturbed young psychic named River Tam." Source: the Firefly Wicki.

In our real universe Miranda is one of the moons of the planet Uranus. It is a haggered, weathered moon where you could almost believe Reavers would live. Click here to learn more about Miranda via NASA's website.
