Forrest is the son of Leo and the cousin of Siegbert, as well as one of the two grandsons of Garon. Like the other children of Fates, Forrest was placed in the Deeprealms to protect him from the war. During his time in his Deeprealm, Forrest developed an interest in fashion as well as a strong bond with his aunt, Elise. One day, Elise gave one of her old hand-me-down dresses to one of Forrest's caretakers. Forrest was so enamored by it, he decided to wear it and Leo called him cute in it. It was at this moment that Forrest began learning about fashion and learned how to sew over the years in his Deeprealm. Even though Forrest knew that boys did not wear skirts and dresses, he learned to make feminine clothing and continued to wear them.
