On the continent of Babel, alchemy was banned centuries ago after nearly destroying civilization through warfare. Now, in the year 931, that fragile peace shatters when the nation of Lustrice resurrects forbidden alchemical weapons to launch a continental conquest. Six neighboring countries unite under the banner of Envylia to crush the threat, and alchemy vanishes once more into legend. Two decades pass in uneasy silence. A new generation grows up knowing only peace, unaware of alchemy's true power or the cost of wielding it. When strange phenomena begin appearing across the land, whispers of alchemy's return spread through the shadows. Seven individuals bearing the marks of the deadly sins find themselves drawn together by fate, each carrying secrets about their past and abilities they never understood. As ancient forces stir and the line between salvation and destruction blurs, these seven must decide whether to embrace the very magic their world feared, or watch everything burn. Their choice will rewrite the continent's future.
