Aeryon return home dejected. He did not return to his residence and instead goes to his tent to take a nap.
He did not return home because he did not know what to say to his wife.
It could not be said that the death of Garron is not his fault.
He is not the initiator of this matter and he is not the one that pierce the body of the Viper.
No one expected that Ogura would rebel against his own father and stage a coup.
No one expected that the attack would be so fierce and swift and that the warriors that Garron had set up could not defeat Ogura forces.
But Aeryon feel responsible nonetheless. He is not sorry to Garron. After all he did his best.
He just did not know how to face his wife with clear conscience.
Even though he did not love his wife, Aeryon did want to live peacefully with Ayera. This desire did not change from the moment he married her.
