Esta serie sumerge a los lectores en un mundo primitivo donde la humanidad no es el depredador principal, siguiendo la lucha de un hombre por sobrevivir contra bestias formidables. Armado con conocimientos de su propia época, reúne a los humanos nativos y los lidera en una lucha desesperada por la dominación. La narrativa traza su transformación en emperador, pero también profundiza en las oscuras complejidades del poder, la traición y la violencia inherente que acompaña a la comprensión avanzada.
A 17th Century curate, James Blades, finds himself transported to a virginal England, unsullied by humanity's building and detritus. But here, the top of the food chain is the Null, mighty beasts who consider the hole-dwelling humans as food animals. Marshalling his knowledge, and returning to our Earth for weapons and useful humans, Blades takes on the Null in pitched battles and teaches the humans to have self-respect. He becomes Emperor. But with knowledge comes treachery and violence...
Thomas Blades has been released from his time as God-King in the alternative world he fought and ruled over. His descendants rule and fight but he cannot bear to return and meddle in their lives.
