“glowfic” apparently. written in a roleplay forum format.
This is not a story for kids, even less so than HPMOR. There is romance, there is sex, there are deliberately bad kink practices whose explicit purpose is to get people to actually hurt somebody else so that they’ll end up damned to Hell, and also there’s math.
start here. or don’t, of course.
Reading a bit of this page convinced me to never read this Isekai into hell story from Yud. It isn’t even that im against edgy hell themed stories I mean Dante Alighieri did it well, and the planescape setting in dnd is not bad imho (it does have the same devils/demons split as this story so very original Yud). But the rest reads just as tiringly ‘Lesswrong nerd out rationalizes DnD rules’. Using a specifically crafted sentence in a wish spell to get antimatter bombs to destroy a fort which protects the ‘makes you a god/kills gods’ stone.
(I don’t mind people who do enjoy it btw, it just screams very not for me)
