O-App-Pesi is a Padjal in Final Fantasy XIV. He was a more prominent figure in the original 1.0 storyline for Gridania, but in Final Fantasy XIV: A Realm Reborn he is only featured in the quest line surrounding Odin and the level 50 Leatherworker Quest.
O-App-Pesi was given to the care of Stillglade Fane in accordance with ancient law. There, Brother E-Sumi-Yan raised him, and instructed him in the ways of conjury and communing with the elementals. O-App-Pesi's talents grew mightily, so much so that scholars believe he could have been Seedseer in another age. In this one, however, the birth of Kan-E-Senna precluded that possibility.

O-App-Pesi is one of the few who knew the truth about the secret mission some gridanian soldiers were carrying out. Khrimm, the son of a couple of soldiers who were participating in such a mission, discovered that they were hiding the truth about their parents' whereabouts which led him to burn a Hedgetree. O-App-Pesi and Lewin accompany a group of soldiers to the site and defeat the furious elemental but Khrimm becomes a wildlings and ends petrified. O-App-Pesi says that the Khrimm's woodsin is very strong and that to purify it, it may be necessary to sacrifice Dunstan. Fortunately, during the purification rite, Brother E-Sumi-Yan manages to purify the boy without sacrifice being necessary.
O-App-Pesi mainly appears in a quest line surrounding the primal Odin, who has been stalking the forests of the Black Shroud since the Calamity, always returning some time after his defeat. In the final quest, "Fear and Odin in the Shroud," he draws Odin to Urth's Fount in hopes of better researching the primal's unusual recurrence. After he is defeated by adventurers in a trial, E-Sumi-Yan discovers the Zantetsuken has abnormally high amounts of aetheric energy. They conclude that "Odin" is actually a host for the sword itself. Just then, Bowlord Lewin arrives informing them that the Zantetsuken had been stolen by one of his men. The Padjal conclude the man's soul was taken by the blade to become Odin anew.
Like all Padjal he has two thin horns growing from his head. He has a slightly darker skin tone than the other known Padjal, and darker, shorter hair. His eyes are pink.
Not of the prestigious Senna family, and not Stillglade Fane's Guildmaster, O-App appears as casual as any normal child, wearing a short-sleeved shirt and shorts. However, like all Padjal he is much older and wiser than he looks, and respected throughout Gridania as a valued bridge between mankind and Elementals.
