After a quarter million years of marriage, Deus wanted to give his wife something special, something that would represent them and the hard work they put into making the perfect environment for them and their children. So, he built a terrarium and called it Earth. In it, he put copies of himself and his wife and brought them to life.
But, Earth starts to change. When Adam and Eve, the copies of Deus and his wife, start having children and those children become murderous, Deus implores his children, the Four Horsemen, to bring Earth back to its perfection before the fast approaching anniversary party.
Famis, Morty, Bella, and Haley begin their endeavor to bring order to Earth but as the population continues to grow, life on Earth becomes more chaotic and many social problems arise. With the help of their cousin Lucy, they create another terrarium to send the truly awful, Hell. As Lucy continues to build Hell, the Four Horsemen become smaller to enter Earth so they can influence the people to not kill, lie, rape, thieve, or own other humans, and generally bring peace back to the terrarium.
