Hello, this is my first post in the lore forums, and third post in total.
As i don't have Oblivion, i've read about it's and SI's plot on UESP.I noticed that the lore states that the Greymarch occurs at the end of every era.
There are several things that suggest that whoever came up with SI's lore didn't pay that much attention to other parts of the lore.Not to mention how cliche it is, (then again, it's an expansion for Oblivion, even though it has some great Morrowind-esque aspects)
The blasphemy is that it states that the Daedra Princes cursed Jyggalag so that he must remain Sheogorath all the time, except at the end of an era.An era is a mortal concept to help divide time by extremely significant events, and Jyggalag was cursed as Sheogorath long before mortals even had a concept of eras, possibly before there even were mortals.How would the daedric princes know about
eras then?
While it is possible that eras do have a higher significance than simple concepts, it was shown that a mortal (Well, depends if Tsaesci are immortal like Mysterious Akavir.Then again, Mysterious Akavir is probably imperial propaganda) in the 2920 series, in the last book declared the Second Era, which was officially accepted as the next era. http://www.imperial-library.info/mwbooks/2920.shtml

Nothing much to it really - The Daedra probably have their own eras and record of time in their own realms.

Yes, but it seems ridiculous for their new era to nearly exactly coincide with the end of the third mortal era.

I had interpreted the end of an era bit to mean the end of an era in the Shivering Isles. The fact that it coincided with the end of the third era of Tamriel was coincidental. From what I recall, in fact, the Greymarch has happened regularly every 2000 years.

It happened because there was another Shezzarine (The CoC, assuming KoTN happened) and Jygglyag broke free because Lorkhan's heart (divine spark) was free, and so Jygglyag could be re-born. I can't explain my theory as well as the word Merchant can in my signature.

They aren't parallel out of coincidence.

Taking a look at the timeline at TIL, these were the happenings circa previous Greymarches:

#1

#2 (if the dragon break lasted 1008 years)

#2 (if the dragon break lasted 150 years)

Incidentally, in the construction set, the player is named Bendu Olo.

That's a good point, but it still stands that the Greymarch coinciding with the end of the third era of Tamriel was coincidental.

Perhaps, as the Serpent's avatars intervene on Mundus, his own rule is weakened, and this is the Greymarch.

We know the Serpent and Sheogorath are one in the same, or the hole from whence the Padomaic entered creation, as Lorkhan's Heart was taken from his chest.

What does the ES world run on? Symbols. Symbols, Symbols, Symbols. Making arguments like "It's ludicrous that event X is based on event Y because event Y is an arbitrary human construct" would be right in RL, but not in TES. In TES, event Y may be an arbitrary human construct, but because Nirn is (and by extension, Humans are) the symbolic center of the universe, event Y holds symbolic value to humans and so, therefore, it holds symbolic value outside of Nirn as well. It is entirely conceivable that Grey Marches happen when Joe Mortal (comparatively speaking) declares it to happen.

Now, one could argue (and some of the people above are arguing) that correlation does not imply causation; that an era change occurs because of some greater reason and that greater reason also triggers a Greymarch. I'd be willing to accept both arguments, for a lack of information.
