Topic: What I imagine the future holds on Carcosa.
Click here for James's blog post about Carcosa: http://lotfp.blogspot.com/2011/09/this-is-carcosa.html
In it he writes: "Carcosa has a history, and a major difference between Carcosa and most settings is that humans aren't part of the setting's history. Humans were just lab animals (hence the color coding) who experiment on each other now (the rituals) because that's what the all-powerful Snake Men did and humans now want to be all-powerful! Now humanity is free as 13 separately breeding species, making their way in a very hostile world. Will humanity rise from this barbarism to create an Age of Humanity on Carcosa, or is the story of man just going to be one of extreme cruelty on the way to being eaten by radioactive dinosaurs?"
James is right as far as he goes. But he leaves the future as a question. Of course, each referee's Carcosa will have its own, unique future. Here's how I see the long-term future of humanity on my version of Carcosa:
The high-tech artifacts of the Space Aliens are mankind's ace in the sleeve. In what is perhaps mankind's only stroke of good luck on Carcosa, the Space Alien armada that made a hard landing on Carcosa had a lot of powerful high-tech stuff that humans can easily use. Humans out-number the Space Aliens, so eventually the humans will kill all the Space Aliens and own all their stuff.
Laser cannons. Tanks. Submarines. Aircraft. Robotics. All the way up to nuclear weapons. The Old Ones and their minions will, over a long period of time, get blown away by men armed to the teeth. Most importantly, sooner or later someone is going to nuke Shub-Niggurath, and then it will all be over save for the mopping-up. Since Shub-Niggurath is the source of the vast majority of monsters on Carcosa, taking it out will put an end to the generation of new monsters.
As a fringe benefit, as Old Ones are destroyed, sorcery will ipso facto also be destroyed. That ritual that summons Nyarlathotep won't do you any good after Nyarlathotep is destroyed.
So I think humans will end-up wiping-out all other sentient things on Carcosa. Then the humans will turn their weapons on each other. Remember that skin color differences are pronounced on Carcosa. Also remember that the 13 different colors of men on Carcosa are not fertile with each other. There will be no rapprochement. It will be wars of genocide. Either one color will wipe out all the rest and then continue on, or ultimately nobody will be left standing. My instinct is the latter. So after humanity wipes out everything else on Carcosa, men will finish the job by wiping themselves out.
Nihilism at its best.
