Kaelen, a fallen noble, is betrayed by his beloved and exiled by humanity—only to awaken the Abyssal Demon Lord's supreme bloodline in the lightless abyss. He rises with a cursed serpent-woman by his side, vowing to tear down the hypocritical gods and divide the sun among all races. In this world, light is a weapon of the powerful. Human nobles drain their own kind's blood to fuel "divine sanction" and oppress dissenters. The demons and beast tribes are the true victims—starved of sunlight and hunted. The protagonist's struggle is a war against class oppression. When the magic altar is destroyed, an energy tsunami shatters the barrier confining the beast tribes. Tens of thousands of starving warriors surge into human territory—igniting a colossal war that engulfs humans, demons, beasts, and gods. Kaelen must unite enemies, break the gods' monopoly on light, and reshape the world.
