She eventually gained the attention of House Pherae itself, becoming the personal guard to Lady Eleanora. She is betrothed to fellow knight Harken.Isadora holds steadfast loyalty to house Pherae, in particular to Lady Eleanora. Though she is a believer of the Church of Elimine, she feels that her duties as a knight goes against the teachings of Elimine, even stating that she holds far too many "sins". Speaking to Renault, Isadora knows that her responsibilities as a knight and the things she has done as one are for good reasons. Yet, she deeply regrets the lives she has cut down in service to Pherae. Though she seeks vindication, Renault offers her none, simply telling her that her doubts make her human and she should use those doubts to discover an answer on her own, even if she may never find them.

The revelation that he survived was both news of great joy, but also great pain. Having already "lost" him once, Isadora greatly fears that he could possibly leave her once more. Should the two rekindle their bond, Isadora weds Harken after the war with their bond a topic of envy for how strong their marrige is.
