*written to the soundtrack of Shadow of the Colossus*
Ah, Earth. The lovely green planet humans have squandered, pillaged, and raped for thousands of years. Humans really are wonderful creatures, right? It seems that a new and exciting species gets driven into extinction so frequently that it's only a matter of time before the only creatures left on the planet are humans and the animals we domesticate. Well, guess what? That happened. If it's not human, dog, cat, or livestock, every species of animal on Earth has gone extinct. Which means the cycle of nature is supposed to go completely out of whack and drive everything else into extinction. But, humans - being the clever little bastards we are - were somehow able to avoid all that in the comfort of our scientifically glowing cities. Or, we did. Until the year 2112. As it turns out, the Mayans forgot to carry the 1.
They also didn't take into account that there were a few thousand creatures made of rock. On 2112, they emerged. We tried shooting them. We tried explosives. We even tried shooting Nintendo hardware at them! All that got us was a few thousand pissed-off creatures made of rock. Even if we started it, these behemoths of stone - the terms Titans and Colossi both used for them - seemed determined to finish it. By 2113, even if we still had all our nice shiny gadgets, pretty much all our cities were being destroyed and ruined. The ruins - while still inhabitable - weren't as nice as the newfound capitol of humanity. It used to be called Manhattan (or New York, depending on who you asked) but it was now called Salvation, and was armed with massive cannons to at least ward off Titans. As if that isn't weird enough, some people among the many ruined cities of mankind claimed to - get this - hear the voices of the Titans/Colossi. At first, people dismissed it as crazy talk spoken in a quest for attention. At least, until a fellow named Odin Silversteen started spreading the "words" of the Titans/Colossi/whatever you want to call them.
Odin was right on every account. He said that seven Colossi were going to march upon Salvation? A day later, there were seven behemoths of stone at the one not-ruined city on Earth. It was when Odin said creatures of the wild and plants would start growing again that people called him crazy. Ironically enough, he was stepped on by a Titan the next day, and died. But a week later, at the spot where he died in what was once Seattle, Washington, there was grass. Slowly, more grass grew. In the year 2115, people started reporting sightings of wild animals, despite how obviously impossible it was.
Since Odin's time, others with the gift of hearing Colossi have emerged, and conveyed the message of the big guys perfectly well. They were fed up with humans destroying their home, so they came up in 2112 to deal with it, or at least scare humans into respecting the earth. Aside from the apparent ability to not die no matter how many times we shot them, Titans had power. The forces of life were theirs to command, so when they were done exterminating harmful humans in an area, plants and animals were appearing again. By 2120, the two sides of the so-called Colossus War were equally matched. Humans discovered that Titans had a weakness to nitrous oxide, and Titans/Colossi had plenty of human support. Currently, the war is at something resembling a stalemate.
In regards to the title, I feel it should be fairly obvious which side is which ^_^
Those who still want these guardians of nature dead would be on the sci-fi end of the spectrum, with big machines, flashy technology, and even robotic implants! Supporters of the Colossi would be more on the fantasy end, with the support of the Colossi, any war monsters they may have spawned, and maybe even some magic in the case of a few rare individuals :O
This is the part where I inquire as to the amount of interest you carry toward this idea.
