Here’s a map I’ve prepared for Children of Man (now available for pre-order!). It shows the Saharan settlements on Saturn’s moon Enceladus in the year 3174, twenty-six years after the events in Servants of Man. As you can see, the capital is New Gambia, named after the royal gardens along the Gambia river south of Dakar. Aside from its administrative functions, it serves mainly as a transshipment port for the moon’s space elevator.
Enceladus’ true wealth lies in the lowlands around the south pole. There, geysers gushing from faults in the long, parallel rift valleys bring up salts and hydrocarbons from the subterranean ocean. Some of the spray escapes into orbit, but much of it falls back to the ground as a mineral-rich snow. Snow mining along the Damascus and Baghdad Rifts has turned Enceladus into one of the Kingdom of Sahara’s most important off-world colonies.
Readers will recognize some locations mentioned in Servants of Man. These include Ebony Ridge Observatory, located on the equator to keep an eye on the shipping orbits, and Fort Saladin, located on the Damascus Rift with easy access to fuel for its missiles.
