Probably my greatest fear is knowing that the universe will one day end, most likely by the slow decay of entropy but maybe in some horrifying Big Rip or Big Crunch scenario. This wikia helps to ease that a bit, because in a way I get to imagine what it'd be like for everyone else. The multiverse as a whole would keep carrying on, right?
This also gave me the idea to weave together something a bit like a story. Not a specific story, actually, more of a setting. But it'd be a set of -verses that work together to make sure sentient beings from all universes can live and work together happily, or at least that's the idea.
I've started with the Hubworld, and I intend to keep going with some other stuff. Of course, it's not going to be perfectly shiny and wonderful. There's going to be conflict; the "defense mechanisms" I mentioned on that page are probably going to be some of the first things I'll go into detail on.
Let me know if you've got any thoughts on this sort of little mini-project.
