So, this might be a futile attempt to rationalize inconsistencies wrought by game design rather than relevant lore, but I've got a few questions about our favorite slandered One-Eyed Nordic king, Olaf One-Eye. Particularly, that he's entombed in a Draugr crypt, and is quite a formidable Draugr himself.
But weren't the Draugr of Skyrim remnants of the Dragon Cult? As in, cultists would go through specific necromantic rituals and mummification processes to become Draugr, and serve their Dragon (Priest?) overlords even in death. But Olaf's reign started 1E 420, whereas the last known remnants of the Dragon Cult were found in Forelhost around 300 years prior.
Do you suppose that even after the Dragon War, ancient Nords continued the practice of Draugr'ing their dead? Come to think of it, Jurgen Windcaller is entombed in an even larger Nordic crypt, and he came around long after Olaf One-Eye. So, in that case, what was their modus operandi for Draugr? They seemed to continue the practice long after the fall of the Dragon Cult; was it reserved for masters of the Voice, or certain Nord heroes?
edit: what other Nordic ruins are known to postdate the Dragon Cult?
