The World of Ephesus. A vast world plagued by Breaches containing countless Beasts of Corruption. A World on the brink of ruin as the Four Human Lineages defend the last bastions of Humanity! With the power of Gem Masters standing against the Beasts of Corruption, the flames of Humanity seek to burn ever brighter. In such a world, in the Mortal Branch of the Asmodeus Bloodline, Alexander awakens a Gem Socket that others consider defective. A Variant Gem Socket. Looked down upon by those who do not understand it, this supposed defect may just be the solution that the burning embers of humanity were waiting for. Follow Alexander as he entirely warps the perception of what a Gem Master is- as he embarks on a journey to become...The Empyreal Gem Master!

In every story, there exists the hero and the villain, the protagonist and the antagonist.And like every story, the hero always wins, and always gets the girl.But what happens now that I died and became a villain in the last book I read? Not even a proper villain, but one that the protagonist kills in the early chapters.I don't want to die again, and I don't want that simp of a protagonist to walk all over me. Maybe I should just become a better villain.I've always admired the smart badass villains that took on the protagonist. Maybe I can be one of them, maybe I can win—the first villain to win against the hero.I'll rewrite this story into one where I become the greatest villain. Call me sick or evil, but it's my time to shine.
