Blaze has been a pit fighter all his life, and it is a life he hates. The only thing that keeps him going is that if he stops, he risks losing the only thing that matters to him: his dragon, Erie.
Ken and his dragon Nevada were once victims of the pits, stolen from their normal lives and made to fight. Now, they work to bring down the pits they despise, though the battle seems futile.
