Evil Fiends
A century ago, the spirit veins fractured, and the rifts to the Nether Realm tore wide open. Evil fiends trampled the daylight of the mortal realm, tearing through the warmth of human civilization and turning thousands of leagues of land into a world-devouring purgatory. Heartless, thoughtless, emotionless, and fearless, their sole obsession is to gorge upon the flesh and blood of the living, devouring every spark of life in the mortal realm. Grade-five fiends run rampant through the ruins; beneath the night, there is no way out, no stroke of luck, and no salvation. Humanity retreated into isolated barrier cities, taking spirit energy as their blades, bone as their armor, and their own lives as sacrifices to the cause. The Central Demon-Subduing Academy established teachings across the Seven Domains, training the world's last demon slayers and keeping the flickering embers of humanity alive on the brink of extinction. Once, twelve Realm-Extinguishing Exorcists sealed the heavens and earth, shielding humanity from destruction. Yet now... Ten have fallen as martyrs, returning to dust. Only two supreme masters remain in this world—their lifespans waning, their flames flickering out. As these final guardians reach their end, as the barriers decay year by year, as the evil fiends steadily evolve, and as the Nether Realm rifts expand with each passing day, geniuses from the Seven Domains rise to face the crisis. The transition from old to new is imminent. The dark night continues to swallow the mortal realm. This century-long battle to the death between humans and fiends, life and death, survival and annihilation— has only just begun its endgame.
