Rhexx is a "lore" YouTuber. I put lore in quotes cuz he makes up like 90% of the shit he talks about. It is the video in the link above.

As for DBs, there is no observable difference between Emperor Dragonborns and Dragonborns. Emperor Dragonborns are just Dragonborns. The main source on this is the Book of the Dragonborn.
