1061 years after humanity has ruined itself through nuclear war, its remnants were forced underground, where only two things matter, complete faith in the sun and meeting the "angel's" radiation quota's. Among the tribes of these underground settlements, there is a forgotten prophecy, known only to the whisperer's of the tribes: "And there shall come one, that once touched by the sun will strip kings of their authority, and bring ruin to the enemies of his people."

Lumis, a young but talented tunneler is thrust into this brutal world where all is not as it seems. Brilliant yet rebellious, he is burdened by doubts about his place in a system that demands unquestioning loyalty. As he faces near death challenges that is everyday life for a tunneler of the tribes, he begins to uncover strange secrets about the "angels" and the truth about surface. What's more is that there are even stranger whispers spoken amongst the higher ups of the tribes, whispers about a prophecy, a prophecy that he may be a part off.

This world is a blend of ancient ritualistic practices and futuristic technology. Expect the 'chosen-one' trope, and lots of political intrigue later on. To sum it all up, it's a scifi-fantasy, a story about a tribe trying to fight for its freedom against an intergalactic empire, and the messiah figure that will lead them to freedom or... extinction.
