BEST IDEA EVER!!

Okay that's probably a bit much. But still.

So, z10: Apocalypse is a variant of Future d10, also known as d10: Visceroth Cluster.  The Visceroth Cluster is a science-fiction setting, a space opera if you will.  The thing is though, I've imagined many moments that are both a part of that setting, and a part of getting to that setting.

It all begins with a near-future apocalypse, an electromagnetic storm that ravages the atmosphere and disables a lot of tech.  At this point, adding in a nuclear apocalypse might be a bit much, but it would further drive a need to go to space, and could house a neat story of conflict, intrigue, and opposing values.

Much later, the project which had caused the electromagnetic catastrophe is uncovered, and becomes redesigned to help create atmospheres on other planets by using the electromagnetic charge to ionize the atmosphere... or something.  Mars is colonized, then eventually Io, and finally Titan.  There's a whole substory here about Io trying to take over Titan before it was considered a member of the Coalition, known as The Titan Chronicles.  This actually helps understand the conflict in the Distress on Denore Campaign for the Visceroth Cluster Setting.

Needless to say, countless stories populate the history and the world of the Visceroth Cluster, and I realized, what if it was a series of novels in The StoneBridge Residents, because I had the idea that one of the characters wrote fanfic based on a character story that exists in the Visceroth Cluster, the character being Phoenix.  Anyways, it occurred to me that while I could include the idea of the novels in the z10 campaign, I could also think about it as a step of the origin to help set off the series of events that lead to The Visceroth Cluster.
I also like it because it's almost representative of how the system came to be, as it was originally a zombie game, that I altered to craft a sci-fi game, which I then sculpted a variant off of that to make z10.  So in a way, the idea that the z10 world has the Future d10 world in it, is a really fun/neat thought for me.
