“Combat is an equation. Those with intelligence have a natural advantage.”
Aion is the main boss in Chapter 18x: Imprisoner of Magic (Chapter 19x in Hector's Story). He is a member of the Black Fang, known as "The Owl", although he is not an original member and serves under Nergal directly as opposed to Brendan Reed.
A very arrogant man, Aion believes himself to have intelligence above all others. It is this intelligence that granted him his name among the Black Fang, "The Owl". It also seems as though Aion is somewhat prejudiced against the Nomadic people of Sacae, similarly to his 'sprite counterpart', Marquess Araphen. He refers to Uhai, the Sacaen Black Fang member previously defeated by Eliwood's group, as "useless".
Aion was assigned to defend the entrance to the Dragon's Gate on Valor, The Dread Isle, from Eliwood, Hector, and Lyn's forces. However, after the player's third turn, Kishuna, the Magic Seal, appeared, rendering Aion's magic useless. When he appears, Aion seems to recognize him, calling him "good for nothing". It is unknown if Kishuna is more well-known than previously thought, or if Aion is one of the few who knows of him.
