Today’s setting is a bronze age, air technology, supernatural, opera.
Before Rome was an Etruscan outpost, a massive air war waged in Egypt. Stretching up the Nile Valley, took to the air. Using gliders and powered flight, the Egyptians took the skies back.
These gliders and small aircraft, as seen in the tombs of the Pharaohs and their kin, were war planes, with seats for archers as they tried desperately to take control of the skies back from the dark and shadowy creatures that flew from a fissure in the Earth. Flying up from Upper Egypt, they swept the land and were a plague upon the people of the early dynasties.
