Alright, I have successfully finished reading this thread! And after reading some of the pages in Perfect Memento in Strict Sense a lot of my questions have been answered, but I still have a couple.
First, we all know that shinigami hunt down and fight celestials. If (or when, really) the celestials win then they are allowed to continue living despite having lived much longer than they were originally intended to. So, does this apply to all of Gensokyo's inhabitants? Can a sufficiently powerful youkai theoretically defeat a shinigami and avoid death or is dying of old age a completely different force? I'm guessing the answer to this question is probably no but I figured I'd ask just to clear it up in my mind. Also, when a shinigami fights a celestial, are the two of them bound by the spellcard rules or is the fact that the shinigami aren't from gensokyo enough to let them out of the contract? Sorry if this is cleared up in PoFV. I've never played it.
On a similar note, What is Rin's role in this? The information I've read seems to suggest that she takes people's bodies to be burned in the Former Hell of Blazing Fires, but all the fan work I've seen of her seems to have her collecting souls. Is this a purely fanon thing or am I missing some important key here? And while I'm on the topic of the Former Hell of Blazing Fires, what exactly is it's role? Is it still the place where the yama send souls with bad karma, or is it just like the Palace of Earth Spirit's garden or some other fitting analogy? And if it isn't where souls are sent to be punished anymore, where is the new hell? Is it located nearby in the underground or moved someplace completely different.
Sorry for all the questions. Simply trying to learn.
