Please do not bash me here, I may have things confuzzled.
From what I know and read, Talos was Dragonborn. He founded the Empire and became Emperor. Because of this The Blades followed and became his bodyguards. Each child after Talos was automatically Emperor/Empress. Then all of sudden the Spetium line was wiped out with Martin’s sacrifice. However, according to the nim wit Blade chick girl, she said a person with the blood of the dragon has always sat upon the throne.
So uh doesn’t this technically mean you’re the emperor?
