Cailyn lost her closest family members, her parents when she was only in her twenties, leaving her to take care of her younger brother alone. Thankfully she had people she could lean on, and while growing up grew quite close to the Levi family. It didn't take long for Apollo to become rather smitten with her himself, often coming up with whatever excuse he could to go see her. Things took a turn for her once again, when her younger brother, just a year older than Apollo, passed away from an incurable illness. The incident changed her, causing her to become seemingly more fragile... Apollo often was the only one who could get her out of the house some days. The only one who could make her smile sometimes. Through one of their outings she had the opportunity to meet others, merchants in the under-dark who interact with the Levi family. She even managed to make some new friends through those connections.
