I recently listened to a podcast that featured a story in which Nyx tried to overthrow Hades. Do we know if she ever did—or anyone else, for that matter? The Disney version of Hecate from Hercules the Animated Series tried to do this as well, so I was wond

Newp.

There is no mythological record (at least that I’m aware of) where Nyx tries to overthrow Hades.

I much more like the idea (which I wrote into my version) that Nyx ruled over the Underworld in the time of the Protogenoi, before the sons of Kronos divided the cosmos.

The progression of night to day written into Receiver of Many I got straight from the Theogony, where Hesiod mentions that when Nyx is in the Underworld, Hemera (daylight) is above, and when Nyx is above, Hemera is below.
