- This article is about the character Ion. For the mystic arte extension that goes by the same name, see Ion (extension).
Fon Master Ion (導師イオン Doushi Ion?), or simply Ion (イオン Ion?), is the highest leader in the Order of Lorelei, a neutral theocracy currently trying to calm the power struggle between the kingdom of Kimlasca and Malkuth Empire in Tales of the Abyss. He is the only one who can read the Planetary Score and unlock Yulia Jue's seals.
Ion first joins the party in the Cheagle Woods, and from there, continues to accompany them throughout the story. Although he is often seen conversation with the group, he never fights, presumable due to his weak condition. When Luke fon Fabre and Tear Grants encounter him in the forest, he nearly faints due to overexerting his powers. Throughout the story, he is constantly pursued by the God-Generals in order to break the "Daathic Seals" on the Sephiroth Trees.
It is later revealed that Ion is the seventh replica of the original Fon Master. He was created along with six others and chosen because his abilities were closest to the original's. The remaining replicas were thrown alive into the Mt. Zaleho volcano, notably the God-General Sync. The original Fon Master was ill, so Grand Maestro Mohs and Van Grants created the replicas; the original later died. One month after Van's initial defeat at the Absorption Gate, Ion is taken by Mohs to read the Planetary Score. However, the strain on his body is too great, and he dies. Before his death, he absorbs the miasma inside Tear's body, saving her life.
Appearance and Personality
Ion is optimistic and soft-spoken, tending to point out the positive aspects of a person's character, even if their negative qualities are overwhelming. Despite being physically weak and docile, he attempts to use his leadership to lead the world to peace, and exhibits great maturity. He refuses to be a puppet, and creates a separate faction to oppose the strictly traditional Mohs, the second in command of the Order. Unlike Mohs, Ion views the Score as one possible future out of many.
Anise Tatlin - Anise is Ion's personal guardian, in charge of protecting him at all times. They have a very close relationship, capable of trusting and listening to each other in dire situations; however, Ion tends to listen to what Anise tells him to do, as opposed to Anise listening to Ion. Anise became Ion's guardian two years before the events of Tales of the Abyss when Arietta was reassigned due to the replica Fon Master possessing no memories of the past. It is because of her actions, in hopes of rescuing her parents, that Ion dies at Mt. Zaleho. While she feels his death is completely her fault, neither Ion nor the party blame her. Ion clearly states this, and thanks Anise for all she has done for him before he perishes. Following Ion's death, Arietta challenges Anise to a duel, but loses and dies in the Cheagle Woods. Anise promises to keep Ion's legacy strong, and hopes to become the first female Fon Master.
