(Draft, needs refinement)
Iraeon spends the next few years learning everything he can. One day the class is about familiars, and eventually the class turns to summoning them. Iraeon is picked because he is the best academic student.
As soon as he summons the familiar, he notices the same owl as in the forest, and hears "Hello brother." He breaks down crying in the middle of class, no one understands why, up until this moment they had seen Iraeon as an emotionless vessel of knowledge. He hugs the owl and then from then on, the two are once again inseperable.
