I'm pretty sure
@Powerofmind said we'd be replacing our past self, so Faith/Fear will already be chosen by virtue of us having Fear 4 already, and i think everyone can agree at this point that having Saiga as a husband is rather helpful, so even if we went that far back i don't think it would be a problem
We
would be losing physical things like our Creche and T3 shrine, our Painted Stars, our silver men (and/or their fertility), seksi, etc...but even then i dont think PoM would make us redo
everything--i'm imagining back to turn 10 at the earliest--oh, or maybe turn 9. That's when we blew up in an accidental ritual, so i could see us going back to then...in which case we'd already have seksi, but not the silver men or shrine stuff...but honestly only the silver men is a problem, cause we can just build those shrine things again (and maybe i can convince people to get the sacrificial bowls instead of the creche...
). Speaking of the silver men, if we find ourselfs back in reality after they already exist, we should think about a demand either that after they die they must be flayed for their silver for us, or that those who pledge their bodies to us after death will be blessed above all others (I'm imagining a far future where signing up as an organ donor on your driver's license leads to preferential blessings from the gods XD), or something (depending on how cruel we want to be
)
