Born to a Lucario and a Sylveon. Silfie was an oddity among her cousins and other relatives, being a pink mess of a riolu. She never really noticed and made up for being different by having a huge personality. She loved playing with the eevees and the riolus that were her cousins. She met Circe by stumbling across her by chance. She was running around and saw a riolu with a weird ghost-like feeling and didn't hesitate to run up to her.
