Serious answers only again, what classpect would Dagoth Ur of ES3 Morrowind be
quick context for the character in case people don't know who he is:
Dagoth Ur, originally Voryn Dagoth, was a Chimer and one of Indoril Nerevar’s closest friends and trusted counselors before the events at Red Mountain several centuries in the past. After going mad, betrayed and left dead beneath the mountain, he was resurrected and transformed by an Outer God's heart into an ancient ash vampire and eventually became the leader and spiritual figurehead of the abandoned Sixth House. By the third era, he reemerged as a geopolitical threat to all of Morrowind and Tamriel with his ability to influence people's dreams and unleash an incurable plague across Vvardenfell called Corprus. Despite his monstrous transformation and atrocious methods, Dagoth Ur saw himself not as evil, but as the rightful savior of Morrowind, seeking to free its people from foreign influence and current leaders of the country and reshape the land according to his own vision by activating the ancient war machine The Numidium (the Elder Scroll equivalent of Metal Gear, it was used before but successfully in Daggerfall). He was successfully foiled by Nerevar's reincarnation, The Nerevarine, when they destroyed The Heart of Lorkhan- ending Dagoth's life and his servants for good.
