The priests tell us that our world is constructed of the four elements, that the power of the elemental realms shaped reality aeons ago, that the balance they've struck is essential to our very survival. Where, then, is this darkness coming from? How has the balance been broken? Caymus, a young disciple of the Order of the Conflagration, had devoted his life to becoming a Master of his Temple, a priest of the realm of fire. Talented, confident, and popular among his friends, there seemed no reason he wouldn't become one of the youngest masters the Temple had ever seen. The night before his ascension to the highest ranks of his fellows, however, changed it was the night the monsters came. Otherworldly creatures, beings forged of some ancient darkness, appeared without warning throughout the lands of Tebria and beyond. Nobody knew what they were, where they came from, or what they wanted; they seemed only to want to destroy. It was the night that thousands died; it was the night that the elemental balance was destroyed. Caymus needs to understand the malevolant force that drives these creatures, to drive it back from his world and protect the people he cares about, but to do so, he'll have to be stronger—braver—then he's ever been before. He'll need to venture out from the safety of his once-safe Temple. He'll need to learn to depend on those closest to him. And he'll also need to discover the secrets of an ancient warrior who seems, somehow, connected to him from across the The Knight of the Flame

We're still alive. The terrible army of the Sograve—the nigh-indestructible force that destroyed so many lives on its rampage through the world—has been stopped, somehow, at Kepren, and the people of Tebria can finally take a breath and rebuild their broken lives. Caymus, the young disciple of the Conflagration who conquered terrible odds to take up the mantle of the Knight of the Flame, knows, however, that the war isn’t over. The alien element still holds the cities of the North, and krealite forces have been sighted throughout the land. Now, Caymus and his companions must discover the invaders' plans, must understand, must fight, so that they can cast it out of his world. Of course, there is another question that needs answering, one which fills the hearts of even the bravest souls with worry and dread: Caymus isn’t meant to fight the Sograve alone; where are the other Knights?
