The Great Mushroom War

1000 years ago a demonic power rose over earth in the form of one man, known to us as The Lich. The Lich once ruled over earth with an evil that was kept hidden for many years. The Lich hated all of earth's people and wanted to see them suffer, he just needed an excuse to begin his works. This excuse came in the form of a meteorite which was on a direct path with earth. After receiving information on this imminent disaster he began production of the biggest nuclear warhead ever built, large enough to destroy one quarter of the planet.

Lich claimed this nuke was to destroy the meteor before it hit earth but he planned to use it for something entirely different. Production of this enormous weapon took many years and over time information about The Lich's plan leaked out into the community. This started and uprising which demanded immediate retaliation from The Lich. This was the beginning of the largest war mankind has ever seen, this was the beginning of The Great Mushroom War. The day Marceline was born was the day the war began. Millions upon millions of people died trying to fault The Lich's plans but to no avail. The bomb was completed 5 years after the uprising and a public broadcast went out across the planet.

"Brace yourselves as you are about to experiencing suffering far greater than you can even comprehend, but which is long overdue. You cannot stop it now, the countdown has begun. You are all going to DIE"

The voice of The Lich echoed across the world as total silence fell upon its people. There was nothing they could do, nowhere to run, nowhere to hide. Nowhere except a small secluded sewer hatch in the forest where a group of Humans, later known as the Hyoomans sought refuge near the end of uprising.

A blinding light and a deafening scream travelled across the planet as billions of people were instantly killed. Light faded into black as a cloud of radioactive dust blanketed the sky, blotting out the sun and coating the world in darkness. Silence fell once again as the dust slowly descended unto the people. The bomb had detonated and the radioactive winter had begun.

One year earlier, Marceline and her father came to Earth to visit her human mother. Marceline chose to stay with her mother while her father returned to the Nightoshpere. When the bomb was detonated her mother was killed but being half demon Marceline survived. Now it was only her and a young man named Simon Petrikov among the wreckage of the world. Simon had used his ice magic to protect himself from the nuclear fallout, but sadly the same could not be said for his fiancé Betty, who ran in fear after seeing what he had become. Marceline was not affected by the radiation as she is half demon. The rest of earth's population had succumbed to the radiation and began to mutate. This horrible war, even in all the pain and suffering, was part of a revolution which would completely change the world forever.

Simon and Marceline survived 1000 post-apocalyptic years but after prolonged use of the crown Simon had gone insane, mutated by the ice magic he had no memory of Betty, Marceline or the war. The inhabitants of earth had mutated into an abundance of different species and split off into kingdoms. The Hyoomans were protected from the radiation until it finally made its way into their water system 1000 years after the bomb was detonated. All of the Hyoomans drank from the contaminated water except Susan Strong who found a clean source of water when bringing her son Finn to the surface to protect him from the Lub Glubs. She drank from this water source until the contamination subsided, she never returned to the surface.
