uses amulet of kings , only known artifact of akatosh (except for either the greaves of the crusader or the cuirass of the crusader)
to transform into a giant dragon.... (and becomes one with akatosh)
and exactly how would it be impossible for the char in skyrim to become a dragon?
this could very well be the ending of skyrim, yet another char that's completely random in lore written out of the story by simply turn him into a giant dragon statue
maybe the before indestructable statue in the imperial city will crush at this event, and whatever place in skyrim you are at that moment will become the new spiritual center of tamriel
well outlined opinions please
