In a nation ruled by mercenaries, power comes at the price of your sanity or humanity, or both.
Kalnen is a nation forged with blood and controlled with unstable elemental magic in the form of Vessels; a twisted use of innocent bodies.
Ezlos was a soldier, then a hero for just a breath, but he now subsists under a mountain, torturing unfortunate Obarans to turn them into Vessels for the mercenary houses.
Orun and Zarna are Vessels, the only ones not in chains. Capable of immense destruction at the cost of their sanity. They have managed to gain their freedom, but now must choose their path in a nation that is not their own and would rather use them as living bombs.
The long-lasting peace between the mercenary houses is rotting, their oaths strained, they will soon use Vessels to incinerate their countrymen. Ezlos, Orun, and Zarna travel to the northern Greatlands, each with a part to play in the coming civil war.
Will they fight to stop it or ensure fire, lightning, and blood are spilled?
