Underground arena

After a prolonged period of daring adventures and perilous quests, a letter arrives that has the potential to alter the course of your life forever. This letter is an invitation to participate in a highly exclusive and unparalleled tournament, orchestrated by a reclusive and enigmatic figure known only as The Mistress. This tournament promises more than mere competition; it offers the chance to attract powerful sponsors and amass substantial wealth. However, the most compelling aspect of this brutal contest is the extraordinary privilege it bestows upon its victors: each winner of a fight gains the authority to dictate the fate of the defeated. In this high-stakes arena, triumph means not only financial gain and acclaim but also the unparalleled power to choose the destiny of your losing opponent. (This is my first complex world so I would appreciate a review on how it can be improved)
