Aifread is a legendary pirate who appears, or is at least mentioned, in several games throughout the Tales series. Aifread represents one of several recurring staples of the series, and his role commonly involves major sidequests in which the protagonists attempt to find his lost treasure.
Tales of Phantasia
Tales of Phantasia marks Aifread's first appearance, in which a sidequest involves the group traveling all over Aselia in order to gather all the treasures that Aifread scattered across the land. The man who gives the group the quest itself is interested in discovering what Aifread's greatest treasure was, and ultimately, it is revealed to be an old, worn dress that was nearly hidden at the center of Iselia. The dress belonged to Aifread's wife, and his greatest treasure was love.
Tales of Eternia
Aifread serves a much larger role in Tales of Eternia. He is known as the legendary "King of Pirates" in both worlds, though considering his lack of an Elara, he is from Inferia. Chat, a recruitable character, is his great-granddaughter, and she never lets the group forget it. Aifread also appears to have been extremely eccentric, having designed puzzles involving everything from a board game, to a haunted house, to wind-up duck toys. Keele Zeibel particularly notes his bad sense of style. He scattered treasure around the world as well, and left cryptic clues as to their locations. The legacy of Aifread is one of the "Seven Treasures" of Celestia. It is thanks to him that the group is able to travel across and between the worlds, having created the Van Eltia. His theme song is simply known as "Aifread Theme", though the song "Comical Dungeon" is played in his dungeons.
Tales of Symphonia
In Tales of Symphonia, Aifread is a pirate from Luin who is in need of money to make a new crew and scams Lyla, a money-lender in Izoold, in order to get the cash. The group eventually gets tangled into a sidequest as well. After sending Lloyd Irving and his companions all over Sylvarant, not to mention scamming the group into paying his debt, he shows his true intentions by telling Colette Brunel that he simply wished for her to reflect on her journey, partially because he lost his entire crew when the Giant Kharlan Tree lost control. During this sidequest, Lloyd obtains the "Arrgh, Me Hearties!" title, which gives him a pirate-influenced costume. Upon completing the sidequest, the group also receives the "Aifread's Hat" item, an equippable piece of headgear that grants the highest intelligence statistic boost of all head armor in the game.
Tales of Legendia
Aifread is mentioned in Tales of Legendia by one of his shipmates, Kaz, whom the group can meet in Werites Beacon. He has written notes about rare monsters that give hints as to their locations. If every monster mentioned in the notes is defeated, Kaz will give the group the "Aifread's Hat" item. There is also an item known as "Aifread's Flag" in the game.
Tales of the Abyss
The only mention of Aifread in Tales of the Abyss is the armor known as "Aifread's Hat", which can be bought at the casino in Keterburg. Its description reads, "A hat said to have been worn by a certain pirate".
Tales of Vesperia
In Capua Torim, the granddaughter living in the lighthouse keeper's house is in love with Aifread. Upon speaking to her when the group returns to Capua Torim, she mentions that Aifread has died heroically, and she now wishes to become a sailor to honor his bravery. In this game, Aifread is not a man, as commonly believed, but is instead female and Patty Fleur's original identity. The man who is thought to be Aifread is actually her subordinate.
Tales of Xillia
In Tales of Xillia, there are various purple, diamond-shaped treasure chests, or arks, scattered throughout the dungeons and fields of both Rieze Maxia and Elympios known as "Aifread's Treasures". Aifread was a legendary pirate who was said to have raided many cities throughout Rieze Maxia. However, he disappeared while trying to find the edge of the world. Later, after finding forty of Aifread's treasures, it is revealed that Aifread originally came from Elympios and must have found a way to cross the schism to Rieze Maxia.
