He is the court mage of Avalon, in aabeta, he is a friend of Gerard.
He is recruitable at Loanne PUB with Gerard in the party.
Aries has high magic score, 24, which is very good, but his great shine is his Speed, 20, and his Stamina, 19, two very high statuses for a mage.
His physical choice is no good, and he isn't a Fire or Wind mage to barriers from Valeria Heart or the Ice Sword do oustanding damage.
Aries is a perfect choice for a attacking Water Mage, he is better than Undine, because of his Speed and Stamina, since Undine is lackluster for both.
