So, I've decided to write an epic. Not a just a long story, an epic. It's going to take me a long time, but it'll be cool when it's done.
The story is about a man named Timothy Smith. He finds a book, called the Time Code, and is given the ability to travel through time and visit an infinite amount of alternate universes. For instance, at one point he goes back to World War II, but he's also been to a world of magic and fantasy. Plus, he can travel through time in that world, too.
The Time Code details rules that must be followed by everything. Breaking the rules causes the rulebreaker to be "time-doomed" which means that their destruction is inevitable. See, you can prevent a person's death by going back in time and saving them (also creating an alternate reality where they're alive) but with time doom, you'd save that person from the falling boulder just to have him fall off a cliff. Objects can be time-doomed too. The Time Code is also what powers Timothy's abilities. It works on a karma system. When Timothy accomplishes things, he is given some karma which is tracked in the book. He can spend that karma to go back in time or into different worlds.
The story doesn't have one Big Bad, but rather functions as a bunch of story arcs. There will be recurring villains who wreak havoc in their universes, as well as certain things that exist in every universe, but altered to fit their own world. For instance: Some guy could have a twin in every universe, with each being slightly different. Timothy is the only one who can travel between universes, but there are a select few who can travel through time.
I can't really write this thing on my own, so I'm recruiting people to write parts for me and submit their own ideas for worlds, stories, characters, and other ideas. Almost anything goes, with the exception of crossovers from other media and a few other things I can't remember. Depending on how much you contribute, you either get credited as a co-author or contributor.
Anyway, if you want to help me with this, post some ideas.
