This is basically my version of the 100 after Raven comes to Earth (just a heads up the grounders do not kill Finn in this version, but also if it wasn't completely obvious he doesn't end up with Clarke). The 100 is a tv show about the apocalypse of the world because of radiation poisoning, so man flees the Earth and into outer space in space shuttles now joined and called the 'arc' to try and avoid human extinction. Almost 5 generations later they send a bunch of 'expendables' to Earth to see if Earth is survivable. Problem is that the expendables are a bunch of criminal teenagers so a lot goes on when they are sent down. This is what happens... (This is very much just based off the tv series so I recommend u watch it before u read this fanfic, because it will explain everything! ;) )
