There are a lot of different legends, even among the stories that are in, um, the real world? I guess? And it's clear that not all of them are right. Like, back home....

Zagreus is a minor figure in greek mythology, but he's usually the son of Zeus and Persephone. It seems like he's probably the son of Hades and Persephone here, from what we've seen so far.

Still, there are a lot of common threads among all of them that hold true in most cases, and the Titans and their fates, as well as what they do later, is a common thread.

Besides, there has been a fair amount we have seen so far that has agreed with the myths I've read, at least to an extent.
