Arlenne Serkia receives the opportunity to travel back in time and formulates a strategy to destroy the man who betrayed her. Her plan hinges on Kasadin, a slave known for his exceptional sword skills and striking appearance, whom she takes in as her "younger brother" to serve as her protector and weapon. However, Kasadin's background is more complex and perilous than she anticipates, influencing his own reasons for remaining near her, which include both personal and political aims. If she is not cautious, her efforts could lead to her own manipulation.
