Eli is the sole heir to the Windsor Royal Enamel Technique. He stayed behind the scenes to help his wife Seraphina become the "Muse of Enamel", but their relationship broke down when Seraphina trusted her apprentice Ethan blindly and smashed a royal custom enamel vase. Eli filed for divorce and took responsibility for the breach of contract. Seraphina finally learned the Windsor Technique was lost yet remained stubborn. At Lord Edward’s gala, Eli’s identity was revealed and his old work fetched a sky-high price, ruining Seraphina’s reputation. Eli went to Limoges to build a training base, facing suppression by Ethan’s monopolistic family. He created Return to Purity live to show the Windsor secret skill, stunning the audience, laying the foundation for reviving the craft and breaking the monopoly, and upholding the craftsman’s original aspiration.
