If a man cannot atone for his sins in the course of his all-too-fleeting life, must his progeny then be held to account? Must every subsequent generation be judged as well?
Archbishop Thordan VII is a non-playable character in Final Fantasy XIV. He leads the reclusive nation of Ishgard, and is an unquestionable object of veneration. He holds the highest seat of political authority in the Holy See, and is a major antagonist in Final Fantasy XIV: Heavensward.
Archbishop Thordan VII appears a wise, stern and caring leader devoted to the principals of his faith as well as the safety of his people. He displays a level of cunning, as while he admits to the Warrior of Light of his dealings with the Ascians, he insists on merely interacting with them to discern their motives.
When the truth of Ishgard's founding and of the cause to the Dragonsong War become known, the Archbishop shows his true colors. Thordan VII is ruthless, deceitful, power-hungry and arrogant in his means to end the war with the dragons, maintain the status quo and become a god-king to a new age. He reasons that since Ishgard was founded upon the secret and lies of their forefathers, it being made common knowledge would render everything the people who went through it for nothing, and they would have to answer for the crimes that spurned Nidhogg in his pursuit of vengeance. Refusing to reveal the truth, even after Nidhogg was supposedly vanquished, Thordan VII is willing to imprison his illegitimate son and condemn innocent people to ensure the secret never comes to light. He believes a comfortable lie is better for the people than bitter truth.
Upon becoming the primal Thordan, the Archbishop becomes even more arrogant, deluded and ruthless, believing himself Thordan I and a god-king. He cannot comprehend his defeat at the Warrior of Light's hand even after wielding the primal's power as well as an eye of Nidhogg.
Thordan is flanked by Lahabrea and Elidibus, implying the Ascians have begun to influence Ishgard's affairs as part of their agenda. Though Thordan secretly wants no help from them, he accepted their proposal to learn more about the Ascians and decided to deal with them once the war with Nidhogg would be over.
Thordan summons the adventurer after helping Alphinaud Leveilleur overcome the trial by combat to prove his innocence and that of Tataru Taru. After apologizing for both his Heavens' Ward's conduct and failure to summon the adventurer sooner, Thordan requests a private audience to tell the adventurer of his dealings with the Ascians. When he learns the Dravanian Horde is approaching Ishgard, when Ser Zephirin asks of the adventurer and Estinien, Thordan is indifferent. During the heretics' attack Thordan meets with Heavens' Ward in making final preparations with Lahabrea overhearing. When confronted by his illegitimate son, Aymeric de Borel, over the truth of their city's founding, Thordan explains his reasons and states he hopes the youth would succeed him. Thordan has Aymeric imprisoned in the Vault so his men can divulge who else knows the truth.
During the aftermath of the Vault compromised, his men assume a primal form. Thordan and the Heavens' Ward depart for Azys Lla aboard their airship, the Soleil, to the Sea of Clouds. Thordan and his entourage wait for the adventurer to kill Bismarck before moving in with the aid of the Ascians to retrieve the Key to Azys Lla that the primal had consumed. With the Key in hand, he flies to Azys Lla, once more evading the adventurer.
Thordan appears at the Aetherochemical Research Facility after the adventurer eradicates Igeyorhm, revealing he never intended to be the Ascians' pawn. He tells Lahabrea that his arrogance towards humans and teaching them the means to summon a primal will be his undoing. Thordan uses the right Eye of Nidhogg that had been kept entombed with Haldrath to become an avatar of Thordan I: The Primal King Thordan. Intending to become a god-king and usher in an age of peace, Thordan executes Lahabrea and absorbs his aether essence before descending into the Singularity Reactor at the heart of Azys Lla to access the power of the trapped Warring Triad. The adventurer and their allies defeat Thordan and the Heavens' Ward (in the form of the twelve knights). As he dies, Thordan glimpses something strange about the adventurer, asking aloud "who...what are you" before disappearing into motes of aether.
Thordan VII is fought as the final boss in The Singularity Reactor.
