In  the year 2036 an asteroid dubbed "Apophis" struck the Earth and contaminated fifty percent of its water and atmosphere with an extraterrestrial pathogen dubbed "The SOL Strain." After two years, sixty percent of all human life was gone! The world's governments were struggling to keep their countries together; all seemed lost.
That is where my story begins.
My name is Chloe Cooper and I'm the only known human to be genetically immune to the SOL Virus. During the pandemic, I volunteered myself for experimentation. In order to to keep me safe, I and three other humans were locked away in a vault deep within the Appalachian mountains. There these people who I soon considered my friends ran many tests on me and the virus, however after months without contact from above it was time to put the project to rest.
Cryostasis pods dubbed: "Cocoons" had been built in case we failed. 16,000 years later I awoke to sirens, signaling a whole host of problems. Now? I'm the last one left.
