Abnur Tharn is father to Clivia Tharn, the Empress Regent of Tamriel. He is known as High Chancellor and Overlord of Nibenay, he is an original member of the Five Companions, and also the Imperial Battlemage of the Elder Council.
Abnur is 164 years old and has at least 16 children. It is unknown how he has lived that long, as Imperials often die earlier from old age.
A vision of Abnur Tharn during the Soulburst is seen.
He is a decisive man, and is part of a line of secret Daedric worshippers, which is just one more reason why the Alliances wish to dispose of him. His family is working with the Necromancer Lord Mannimarco in order to combine Nirn with Coldharbour, Molag Bal's Daedric Realm, after realizing the threat posed by the Ebonheart Pact, Aldmeri Dominion and Daggerfall Covenant. However, Abnur, despite sharing his family's traditions of Daedra worship, despises Mannimarco due to his involvement in the Soulburst.
He is the ancestor of Third Era Imperial Battlemage, Jagar Tharn, the progenitor of the Imperial Simulacrum who ruled the Empire for 10 years before the Eternal Champion freed Uriel Septim VII from Jagar's prison.
After Abnur infused the Vestige with divine power with the Amulet of Kings, he helped the remaining Companions reach safety. After this he fled with the Amulet and returned to the Imperial City to attempt to harness the Amulet's power. According to Meridia, the relic's power will be dormant for several generations, and Abnur will not succeed, but will try nonetheless.

"What is the meaning of this interruption? Why have you contacted me?"
Lyris: "Abnur Tharn, you traitorous bastard! I should have expected to find you here!"
Abnur: "Don't be a fool, Titanborn. I'm trying to help you. Your hatred poisons you. Warriors are like steel. When you lose temper, you lose your worth."
Lyris: "Help me? You betrayed us all, then went back to licking Mannimarco's boot before the smoke cleared!"
Abnur: "I did what I had to do. And, as a show of my good intentions, I have a gift for you. But, be warned. Coldharbour will not give it up, easily."
Lyris: "Is that ... ? Shor's bones, it is! Vestige, that's my battle axe!"
