So this idea is only really half-formed, but I thought I'd put it out there to see what other people think of it.

So, Mnemoli. The goddess that can only appear during Dragon Breaks, when time stops being linear. Could it be that she's worshipped by the Hist (and the Argonians)? After all, to them, time is never linear.

This could partially be why Argonian religion is shrouded in so much mystery. It's not that they don't worship gods, it's just that nobody besides them remembers their gods.

There could be an Argonian NPC in Skyrim who tells the player about Mnemoli like, fifty times, but because it's not during a Dragon Break, the player simply never remembers the conversation.

Crazy idea I know, but that's kinda what the Lore Forum is for, huh?

We basically know nothing about the Hist, and they are one of the best candidates (besides the Dwemer) for being truly incomprehensible to (non-Argonian) mindsets. So the best possible answer is: wha? Although, I haven't read the novels, so I eagerly await being corrected on the supposed cluelessness of the world beyond Black Marsh.

Mnemoli is an interesting thing. I might be wrong on this, but is she associated with the Magne-Ge? Or is it just a tenuous link between Magnus the Sun and the Blue Sun?

I've been under the impression that the Hist are much more closely linked with Sithis.

I was of the same mind as well.

Unless theres some hidden "Sithis has been working with the Mnemoli" thing that we dont know about, I am not seeing a link between the Hist and Mnemoli.
