Kriska is a young gnoll who lives a peaceful life in nature among his adopted tribe of Firbolgs. He's learning to become a blacksmith, apprenticing under his father. One day, as he's testing out the new sword he just crafted, the whole village is stormed by a group of masked riders. Overwhelmed, Kriska tries to flee to safety, but he's soon captured together with other young Firbolgs to be sold into slavery. After much tribulation, he ends up in a gladiator stable. At first, the gnoll refuses to obey and fight, but he quickly realizes that he has no choice. In this new world, the rules are harsh but simple: it's either kill or be killed. As one match leads to another, the natural instincts he had suppressed until now start to resurface and slowly slip from his control. Kriska will need to find a way out before the rage and fury plunge him into madness, and he loses the humanity that made him something more than just a wild animal.
