The evil warlock Malick, has decided to take revenge on those who cast him out, using both, his inner circle, and the power of the sun in the palm of his hand.

Tiber Saxon (Earth 818): Tiber was a stubborn yet heroic warrior who held several powerful relics and placed them in various places for others to find. If reunited, they'll unlock secrets of true power. Wil hunts for them.

    I'm the demon lord Queen Mortemseeker. I took over the demon thrown after I challenged Marshall lee and I's mother and over threw her power with my own. I had killed her within seconds and was given the crown. I changed the demon realm making it a much better place for demons. I didn't allow death and destruction anymore. Demons no longer had to wait in a line for days to speak with me instead where put on a waiting list based on the urgency of their problem. Everything was great. Demons where healthier and cleaner. The realm was at it's peaceful state once more. The thing was. I myself wasn't at peace in my own mind.

    Hi, y'all! It's been a few years since I started part one of this story, and the outpour of support is amazing! I honestly had no clue. I'd like to think I've matured in my writing, and I'd be happy to finish! I owe so much of my queer identity to Adventure Time and it's fandom, and with the show ending soon I'd like this to be my personal salute to a timeless show. :^)

    The human race has decided to partake in a devastating nuclear war known as The Great Mushroom War. The largest bomb made has just been dropped, releasing powerful evil and magic into the world. Many organisms, including humans, are now extinct. Civilizations are severely damaged and turned into ancient ruins. Common things like video tapes and CD's and cars are now ancient history. Only two survive the dangerous blast. One: a man, aged 47, by the name of Simon Petrikov and a little girl, aged 7, named Marceline. Marceline, born half demon half human, survived the powerful blast because of her demon "heritage." Simon, however, owns a magical crown that protected him as the bomb went off. The crown provides Simon with the powers of ice and snow when worn atop his head. The crown also gives Simon the gift of immortality, but all magic comes with a price and the crown is slowly driving Simon mad. It has quickened his aging process and has turned his skintone to&nbsp;a pale blue, has elongated his nose and has given him white hair and a white beard. Simon and Marceline were friends before the last bomb went off and are together, trying to survive the apocalyptic world once knows as Earth. Even with the extinction of most life there are many dangers and obstacles that Simon and Marceline must face to stay alive. They are the last of their kind. They are the last of us...

    MODERN AU Note: This is a Marshall Lee x Gumball fanfic, which will contain fluff and cuteness. Mature content will be included, and YAOI. So, if you are uncomfortable with yaoi, I suggest you move on to another Marshall Lee x Gumball FanFiction. I do not own any of the characters from Adventure Time nor do I own Marshall. All characters that will be included in this book rightfully belongs to the former owners of Adventure Time. I only own the plot and OCs that'll help fit into my story line. ENJOY~!
