After eighty years of total war the remnants of humanity on the Nayarit line struggled to survive in sealed domes, surrounded by radioactive wasteland and genetically engineered viruses. It was in the last, desperate years of the war that the first trans-temporal portal was developed at Chiqu, a small research facility holding out on the west coast of North America. As the domes finally failed and civilisation collapsed around them, Iapura led 53 survivors from Chiqu to found a new empire on a parallel Earth. An Earth where, in 1884, Russian and English armies faced each other across America's Great Plains, totally unprepared for the technology of the conquering Nayarit.
Over the next 90 years Iapura's Empire expanded steadily across a series of parallel Earths, absorbing and conquering until it included over 53 separate lines. Finally, however, with its technology stagnant and its ruling council riven by dissent, the death of Manet, First Leader of the Cross-temporal Empire sets the Council onto a slow and irrevocable slide into civil-war.
The Clemhorn trilogy chronicles the interlocking stories of the four Clemhorn siblings: Conrad, Arnold, Donald and Ivy (heirs to the Etu line); their cousins the Perics, and the pivotal role they play in the inter-dynastical wars that follow the death of Manek.
