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
