Abyssal Throne：The Godslayer

Light in this world is controlled by whoever has power. Human nobles drain the blood of their own people to feed what they call divine sanction, and they use it on anyone who objects. The demons and the beast tribes are the ones kept out of the sunlight, and they are hunted. Kaelen was a noble and lost the position. His beloved betrayed him and humanity drove him out into the Abyss, where no light reaches, and there the supreme bloodline of the Abyssal Demon Lord woke in him. A serpent woman under a curse takes his side. The two of them swear to bring down the gods and divide the sun among all the races. The magic altar is destroyed and the energy off it breaks the barrier that has been holding the beast tribes in. Tens of thousands of starving warriors come across into human territory. The war that follows pulls in humans, demons, beasts and gods together, and Kaelen has to get enemies to stand on the same side.
