I've been thinking for a while now that it'd be cool if I could connect all my stories in a Cosmere/Dark Tower way, and I think I've come up with an interesting storyline. I plan to use it, I've even dropped some hints in my latest book, but I don't know how much of it will actually be made known to the reader and how much I'll keep to myself. Anyway, what do you guys think?
The idea is that billions of years ago, a planet sent a self-piloted spaceship up into space with the goal of finding the edge of the universe. Millions of years later it finally reports back that it's found something, and they beam people to it to check it out. What it's found is a gigantic mirror that stretches for eternity in all directions. They call it The Mirror at the Edge of the Universe. The astronauts, of course, break a hole in the mirror to find out what's on the other side, and they release Ohm, the Disease Beyond Eternity. It's a sentient disease that is so powerful it can infect reality itself, and its only goal is to infect the entire universe and in doing so essentially make ITSELF the new reality. The mirror was put there by another ancient celestial entity to quarantine Ohn from the rest of the universe.
So, Ohn gets busy infecting everything it can touch. People try to fight it, and while they can slow it down they still can't stop it. Eventually the king of the galaxy (still working out the details) works out a deal with it: he will freely give it 2500 planets if it will leave the rest of the universe alone. Ohn accepts. Neither of them plan to keep their promises, the king is simply buying time to figure out a way to stop it and Ohn wants to consume planets in peace before it has to start fighting for them again. Haroz, the world in my upcoming story The Gray Ranger is unknowingly the last of these planets. Basically, every bad thing that happens in my high fantasy stories can be traced back to Ohm in one way or another. I want Juryokine to be in on it too, but I haven't thought of a good way to do it yet.
I've found out how to include my other stories as well. The Slayer and the Sphinx and Amber Silverblood already take place on the same world, but they're in a different literary universe. My idea is that in Ohn's universe, there are waystones that can transport you to alternate universes. They've all been hidden away, and one in particular was hidden on a planet that only exists in the dream world. As in, you can only get there by going to sleep and dreaming your way onto it. The celestial entity thought that would keep Ohm from getting to it, but it managed to infect that world anyway by essentially turning it from a dream world to a nightmare. That resulted in the planet being ruled by a living, thinking emotion (fear), which then found the waystone, was taken to another universe, and given physical form there. That resulted in Uthas Drall the Fear Feeder, a Lovecraftian monster that used to rule the world in The Slayer and the Sphinx. Some people from Ohm's universe follow it and beat it, one of them being the man that was historically recorded as being the first Slayer.
That's all I have right now. What do you guys think?
