Nathaniel, having now gotten most of the explanations by now, regarded Hector with uncertainty. "So. I had my ass saved by an old acquaintance I thought died during that early fuck-up, when the unit rolled into town to deal with so-called rioters. Said formerly dead is apparently now a knight, which seems to be the least weird part of this. And apparently he never joined Division VIX. Our unit. So now he lives on a farm just down a road I know used to not be here, right over what my maps said was an old supply bunker, which I sure as hell didn't see any sign of. That about cover all the weird shit involved here?"
The knight gave a nod at that. "Seems to. I'm going to need Roxanne to explain this shifting thing, I guess. Then I'm going to have to ask her whether 'doppelgangers' or any such thing factored into her theory here..." he said, likely all this still overheard by Floyd, and possibly Kathrine.
So, basic idea I had was, every character we ported over was at the expense of another made in this world, right? These could be RPed as this world's equivalents to the characters, all of whom died at some point before the shifting, and all of them having done something differently. Or they could be played as other people. In fact, I'm already thinking up one possible example of the latter.
