Ion (original)

Fon Master Ion or Ion (イオン) is the highest leader in the Order of Lorelei, a neutral theocracy currently trying to calm the power struggle between the Malkuth and Kimlasca kingdoms in Tales of the Abyss. He is the only one who can read the Closed Score and unlock Yulia's seals. It is unclear whether the Fon Master is born with this power or it is achieved with the title. He is calm in most situations, and can utilize Daathic Fonic Artes, though that can be exhausting.

Personality
Unlike the seventh replica, the original Ion hated the Score and became bitter because of what it predicted. While he read the Score and made the citizens of the world happy, he noticed how they were all consumed by the Score and came to think of the world as trash; trash that needed to be eliminated.

He has a tendency of abusing his replicas, despite the fact they are quite defenseless against him. Ion is shown with his seventh replica, who would eventually succeed him as Fon Master, and the reason why he hates the Score becomes clear during that scene.

Relationship with Arietta the Wild
Ion found Arietta in the woods in Rugnica Plains when she was a small child. He was the one who taught her the human language and came to think of her as a pet. What perhaps made him like her at first was that she knew nothing of the Score. At one point, Arietta gave Ion the skull of her liger sister, claiming that her sister had always protected her and so would also protected Ion. After Ion made Arietta his guardian, he warned her that if she ever became useless, she would be disposed of, but she only smiled and said she would always be Ion's side.

As he reached the age of twelve and became further bed ridden, he found much comfort in Arietta's presence and even came to think of her as cute.
