Twenty years after nuclear war broke out, lead-gray clouds of radiation permanently shroud the surface, and the civilization of the old world has been reduced to ruins by flames.
The “pure humans” hiding in underground bunkers have been deceived by the lie of the “Ark Protocol,” believing themselves to be the last spark of civilization. The superpowered people left on the wasteland have split into seven great tribes, struggling to survive amid radiation and mutation. Above the clouds, the Skyborn guard a secret spanning millions of years, waiting for the one born from lightning.
Lin Shen, an orphan from the New Ark underground city, is accidentally infected. He goes from fugitive to the “Root” everyone is searching for.
