Grace is from the Cadin House, a renowned transcendent House of the Rosa Merchant Confederacy. She has a close bond with Charlotte as her personal maid.
Grace is very talented, reaching Origin Level 3 before her thirties, a level that tens of thousands of Origin Level 4 transcendents have failed to reach. This would have given her the strength to have a higher position than a personal maid but due to her close sister-like bond, she decided to continue being Charlotte's maid.
She helped assess the Ascart House and Roel Ascart as potential fiancé of Charlotte but due to a scheme of Alicia, Nora and many others, left believing the lowest of the Ascarts.
