Marc Vitrac, born in 1960s Louisiana, came into a world where the first interplanetary probes unveiled life on Mars and Venus, igniting a global Space Race.

Fast forward to 1988, Marc is stationed at Jamestown, a US-Commonwealth base on Venus, set against a backdrop of sabertooths and dinosaurs, near the bustling Venusian city of Kartahown.
