- —Auron and Kinoc.
Wen Kinoc is a non-playable character in Final Fantasy X who has a cameo role in Final Fantasy X-2. He is a Maester of Yevon and friend to fellow Maester Seymour Guado. According to the Final Fantasy X Scenario Ultimania Kinoc is the Minister of Military Affairs, which is in charge of the general military command. Kinoc doubles as head of the Warrior Monks and oversees the Crusaders. He was once a Warrior Monk himself and good friend of Auron.
Following Auron's fall from grace within the clergy, Kinoc took the promotion for second-in-command originally meant for his friend and rose to the title of Maester within seven years. Though he gained wealth and power, Kinoc began to hunger for more while fearing of losing it. One of his exploits as Maester was the formation of an elite military force for Yevon, the Crimson Squad.
Kinoc assembled the Crimson Squad under the guise of fulfilling the society's demand for a stronger army, but his true intention was to privatize the Crusaders by inserting his hand-reared Crimson Squad members. Feeling threatened by the newly appointed Maester Seymour who was gaining power, Kinoc set his eyes on the Vegnagun, a mysterious machina weapon of ancient times. Rumors of a vengeful presence inhabiting the Den of Woe below Mushroom Rock Road circulated with reports of people seeing the illusion of a "gigantic machina" within intrigued Kinoc and he sent the Crimson Squad aspirants into the den to collect information on the Vegnagun on the same day as the Operation Mi'ihen he was also overseeing would take place, so any casualties would go unnoticed, as he knew the operation would be a disaster.
Overseeing Operation Mi'ihen, Kinoc is glad to see Auron who is now traveling with summoner Yuna as one of her guardians, who expresses his disbelief at Kinoc having been made a Maester. Kinoc notices Auron has changed.
At some point, Kinoc learned that all but three of his candidates and their sphere recorder died in the Den of Woe, and ordered for the quartet's execution to conceal his failure, as it could place his position in jeopardy. Kinoc ordered the Den of Woe sealed with magic.
Kinoc later oversees the wedding of Yuna and Maester Seymour in Bevelle. He orders the Al Bheds' airship Fahrenheit that is attempting to disrupt the ceremony shot down, and the airship departs. Kinoc enlists his Warrior Monks to hold off Yuna's guardians who are looking to save her from the ceremony. Holding the party at gun point Kinoc almost decides to kill Auron when he calls him hypocrite for using machina, banned by the temple of Yevon whose dogma Kinoc is supposed to uphold. Yuna's escape on Valefor allows the guardians to flee with Rikku's flash bomb to meet up at Bevelle Temple. After Yuna obtains the aeon Bahamut from its Chamber of the Fayth, Kinoc arrests Yuna and her guardians with the promise of a fair trial.
Kinoc is ordered by Gran Maester Mika to throw Yuna and her guardians in the Via Purifico. When Seymour offers to personally ensure Yuna and her guardians are killed if they escape, Kinoc offers to accompany him out of distrust. By the time Yuna and her guardians escape, Kinoc has been unceremoniously killed by Seymour as his way of relieving the maester "of all fear." Seymour absorbs the pyreflies from Kinoc's corpse to evolve into Seymour Natus to apprehend Yuna himself. After his death, Auron swears to avenge the man he once knew, vowing that Seymour will pay for Kinoc's death.
Two years later the Crimson Spheres detailing Kinoc's attempted formation of the Crimson Squad, and the attempt he made on the lives of the surviving Crimson Squad candidates—Nooj, Gippal, Baralai, and Paine—surface. While investigating the Via Infinito, Yuna, Rikku and Paine find Kinoc's restless spirit before he transforms into the fiend Aranea.
Kinoc's fiend form, Aranea, is fought as an optional boss in Via Infinito in Final Fantasy X-2.
