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.

Bombadil is a fat dude living in splendid isolation with a beautiful woman, unconcerned about the evils of the wider world. Perfect ideal for Yud.
His story is also vague as fuck, and according to some his more modeled on pixes etc from our world, so it would fit for him to pick an isekaied from our world into lotr char for his isekai from rationalist fantasy world to hell character.
