PROLOGUE
Long ago, two races ruled over Earth: HUMANS and ALIENS. One day, war broke out between the two races. After a long battle, the humans were somehow victorious. They sealed the Irken leaders underground with magic spell. Many years later, humans opened the barrier and accidentally closed it behind them. … They weren't all that smart. Now stuck with the humans, who couldn't remember how to get out, the Irken leaders claimed the underground was their kingdom, and now live in somewhat harmony with those humans. The Irken Invaders sometimes try to free their leaders, but it doesn't always go right….
Even Later….(Mt. Ebott, 201X)
Legends say that those who climb the mountain never return.
"Who cares about stupid legends! Nothing can defeat the power of ZIM!" Zim announced to his absent audience.
He began to peek over the giant hole when suddenly…
"Gah!" He yelled as he fell down into a patch of flowers. "Stupid tree root…"
It looked like there was nowhere to go but onwards, so he started walking.
