Achilles opposed the Scarlet Moon Empire as a member of the Anti-Imperial Movement. In 453, he was arrested by Kraze Miles, a Scarlet Moon commander, for allegedly sheltering fugitives. Subsequently, Achilles was sentenced to death in a effort by Scarlet Moon to silence and crush him and the Anti-Imperial Movement. As was the custom for people sentenced to death, Achilles had the privilege to evoke his "last rights"; Odessa pressed Achilles to marry her and he reluctantly agreed.
During the matrimonial rite, Odessa used a magical ring to blind all witnesses and made an effort to escape with Achilles. Unfortunately, Achilles was felled by Imperial archers during the escape attempt. His dying words to Odessa were, "Defeat the Empire!"; these words later led Odessa to form the Toran Liberation Army, which fought against Scarlet Moon during the Toran Liberation War.
