Adri is a non-playable character in Final Fantasy XIV. He is a former friend of Widargelt Beake who appears in Monk questline. Currently Adri claims to be the true Griffin and assumes the identity of Theobald, the son of King Theodoric.
Once Widargelt goes to Gyr Abania to try to revive the Fist of Rhalgr, Adri interrupts Widargelt's plans by claiming to be the true Griffin and that he is Theobald, the son of King Theodoric. He issues a warning against reviving the Fist of Rhalgr, and goes on to reveal that Widargelt is actually his cousin Theodred. Theobald then leaves, but not before declaring his intention to rule Ala Mhigo.
Eventually Widargelt challenges Adri to a duel. Before the fight Adri reveals his true identity. Once the conversation is over, the battle begins and it becomes clear that Widargelt has the advantage, and Adri summons his minions and resorts to using imperial weaponry. Hamon shows up with Chuchuto and Rurukuta, and they enter the fray to even the odds. At the end of a long fight, Adri and his minions are defeated.
After being captured Adri is taken to Ala Gannha to treat his wounds. Knowing that he would be hunted by the Corpse Brigade for having used them, Adri, still wounded, flees and faces them alone even knowing what his fate would be. Adri's body is buried in Little Ala Mhigo and Widargelt regrets that his former friend could not return to his side.
Adri feels powerless because of his inferior birth, he resents Widargelt for rejecting his royal blood and the power it represents.
