Like you said, they are just obscure texts that aren't canonical, especially seeing as how Mehrunes Dagon is a Daedric Prince and not a leaper demon <_< Kalpa is a real world term that means a variable time span that could mean anything from a life-span of a typical human to an eon. Kalpa only showed up once in any real texts and that was Kalpa's in the sense of the past lives of Pelinal.
Aaah, too bad.
I really didn't mind about the "leaper demon" bit, too - this reads like folktales, where the great are often presented in joke form, I suppose to laugh out the fear(reminded me of Anansi stories, really)- it never means there isn't a grain of truth in it.
But if there's no echo in actual game-books, you're right.
But you see people that worship the Imperial library spout Kalpa everywhere and say that time is cyclical and the world is destroyed and rebuilt multiple times but can't be true from what we know of how of how Mundus was created. Also we know that time is linear and thus the world couldn't be reborn over and over again. That is just the point of view of the nords that the world is a cycle that must be destroyed over and over again even though none of the other races have that belief and that we know that time is linear and the world has never been destroyed before and rebuilt by Alduin.
Would we know if it had ?
Honestly, I only like it cause, well, I get it. Like beliefs in antiquity, that the time was made of "ages", at the end of which there was much catastrophes and miracles, until the new age began. In some beliefs, the old one was consumed in fire for the new one to appear. Only that time was often considered critical : you had to do things right to kick in the new age. There's tons of interesting stuff in Greek / Etruscan philosophies, and in Roman texts. *
I don't know. There was some talk about Lorkhan sort of tricking Alduin to create Mundus. I kinda like that while it created linear time, it might not just be a good thing in the end - world gets old and crumbly (I mean, look at the mess at the time of Skyrim). So Alduin trying to eat the world, might not be such a clear-cut thing - leave everyone you care about be engulfed in destruction, or leave the world to rot. Hehe. Brings some grey to the main quest - and ties to the whole Dagon thing : performed an act of destruction in Oblivion due to some obscure thing with Alduin (mirrored in the joke in the text), so to facilitate the task of Alduin. Or something.
Because there are holes in this theory that Akatosh wants to destroy the world at this time. Why would Akatosh be pissed? Why would Akatosh destroy the world he and the other divines sacrificed so much for such as a lot of their power and their immortality. Why would he come around and destroy those whose worship give the divines power? It just doesn't make sense.
Alduin is the "chief villain", apparently, and it's pretty solid that he is at least a version of Akatosh (doesn't seem far fetched, if he's a representation of time. Death svcks, but you need things to die to have new things to appear. Negative/positive aspect of time.). So that much seems to be in the game anyway.
None to solid on the covenant with Alessia - what's certain is that it doesn't apply anymore. :unsure:
And before you explode, I know I'm talking through my hat with little basis on Lore anyway.
I'm just having fun. Doesn't matter much, I suspect a lot of Lore beliefs and speculations are bent by what you choose to believe. :lmao:
There's so much cool stuff in Lore that remains only in the background of the game. :mellow: Pity.
