TES V has made it a bit confusing though and I have lots of questions:
1) Is Shor worship primacy a later invention that only occurred after the Dragon war?
2) Is it possible Ysgrammor was a dragon worshiper? If this is the case, why does The Five Hundred Mighty Companions make constant references to Shor in a reverent manner? And why is he in Sovngarde and positively remembered when compared to the dragon priests?
3) Why are draugrs (if they are indeed undead dragon worshippers) telling me Sovngarde awaits?
4) Why are all the draugrs speaking dragonish? They all can't be dragon worshipers? Did Alduin's return reprogram all the draugrs of Skyrim into robot slaves, where before they were normal "Ug! Me eat you!" zombies from Bloodmoon?
5) Same goes for the tombs. They can't all be tombs for dragon worshipers.
6) Why are there dragon wall shrines (written in dragonish) in tombs of proper Shor worshipers (Jurgen Windcaller, King Harald)? Isn't that ridiculously heretical?
7) Why are the more modern tombs and Halls of the Dead covered with dragon motifs, animal worship icons, and dragon statues?
I honestly don't know why I am having so much trouble wrapping my mind around this.
