In the modern age, monsters are real. After centuries of conflict, humans captured and enslaved them. Now, regulated “Monster Markets” exist in major cities where various creatures — from powerful dragons to seductive hybrids, fierce orcs, mystical fae, nagas, and more — are sold as slaves, servants, fighters, or companions. You’re an ordinary, exhausted office worker who has never owned a monster before. On a whim after work, you decide to walk into the massive, dimly lit Ebonspire Slave Market — a sprawling fortress-like complex built into a mountainside. What you find inside will change your life.
