My Stolen Destiny with the Prince

On Roslyn's wedding night, a woman named Celeste arrives holding a jade pendant and says she is the one who saved Prince Lucian's life. The pendant is real. The story attached to it is Roslyn's. Roslyn was born into a healer clan in Southmere. When Lucian died on campaign, she used the family's Immortality Charm, which can only be used once, and brought him back. The backlash took her voice for a time and took his sight. She nursed him while he recovered without being able to speak to him. Before he left he gave her the jade pendant and promised to bring her to the palace. She lost it while fleeing. Years later she marries Lucian by imperial decree, and Celeste walks in with the pendant.
