The Year is 2020.
The Planet is Earth.
The names of the countries and cities have shifted, Ghosts and Fairys work side by side, Aliens and Lava-Based Lifeforms watch Doctor Who together, a Robot and a Dragon are the most legendary duo the army has ever seen, and The Prince of Blue-Skinned Ice Australians with Snow Magic fights alongside a simple Human and a less than simple Human, but it is still Earth. But much of this doesn't matter right now.
On the day of October 31st, a fight goes down between good and evil. A world-saving hero, and a shapeshifting assassin of darkness.
One robot enters.
One demon enters.
One of them leaves.
Who will prevail?
Well, you're gonna have to wait a long time for the answer, and even then, it's all up to you and how good you are at a game that doesn't exist yet.
