Sophia, has been a "gift" of the "Nightblade Tribe" since childhood—betrothed to Arthur, the future Alpha, to strengthen the covenant between the Nightblade Tribe and the imperial wolf clan. She was silent and docile, never rebelling, even though Arthur never once looked at her properly.
Years later, Arthur married someone else instead, and set up a farce of a "wedding stand-in" for her. On the eve of the ceremony, he locked her up in a border manor and told her coldly, "This isn’t a wedding. It’s a deal. You’re to disappear quietly."
