At the End of the World by Crisyah

Humanity set out to attain Godhood and failed.

In the ruins left by their attempt, imprisoned in the throes of undeath, their heirs hide from the demons, horrors of the mind reborn as horrors of the world, and the angels, servants of the God they sought to dethrone.

But, inside the walls of a long-abandoned city, rebellion is brewing. The Scions, magic users possessed by mysterious creatures known only as “Archons”, tire of their captivity and plot to gain back their freedom and find the answers to the mysteries of their world.

Yet it’s not only monsters that stand in their way. There are still humans who will fight for secrets to remain hidden, others who don’t wish to see the scales of power they’ve so carefully balanced tip. The Scions might have to follow in their ancestors’ footsteps and grasp for what they couldn’t achieve to succeed. They might, even, have to kill God itself.
