…(Timewatch being that time travel RPG coming out Very Very Soon Now) and then I remembered: I don’t actually have the rights to put up any of that material. I should check up on whether they’re going to OGL it, although I should probably contemplate… I dunno, try to sell them it?
Anyway, the basic concept was pretty simple: imagine a past Golden Age. Then smash it. From the broken pieces, construct our own timeline. Now imagine how the few temporal refugees from said Golden Age are going to feel about that. Did I mention that some of them could give a Grey Lensman a run for his money?
Anyway, your party’s job is to stop them from reversing their horrifying apocalypse. Have fun!
