Well, I've suggested in the past that we have a storyline that covers all of Infinite Histories. I realize that there are blogs that mention ideas, but I figure it would be best if there was a single location where all of our ideas were. Having an overall plot helps to unify all of our stories here. It's a means to making our wiki unique. I am thinking that we should aim to have the equivalent of Chaos Crisis at the very least.
From what I've heard so far, the main story involves a conflict between multiple universes. This blog sums up the main idea: Multiverse Time!. Notably, there was this quote:
"It currently seems most likely that any overall plot would involve a combination of the Xenotech Nexus and IVC (on the Xenotech Nexus page there is a Source with references to IVC terminology). I guess we'll see."
Highly advanced civilizations are using alternate timelines to their advantage somehow.
Civilizations capable of exploiting the resources of other universes.
How much science fiction are we willing to include? Certainly, Multiverse Travel is to Infinite Histories as FTL is to Galactic Crucibles. Would multiverse travel be a recent discovery or something that has been around for some time?
