He comes from the first layer of hell, Avernus and you can summon him whenever you need him. He is a Stern, serious and strong person, who seems to not like to fight with you but never complains. As a lower Cambion he has to do what his Misstress Mizora tells him to do. Lower Cambions aren't even allowed to find a mate in hells. But he starts to like you and secretly wishes you would take Mizora down so he would be free and could finally confess to you.
