The Maahes who looked west. Salim-Aswan was a river-pilot's son who grew up on the old frontier where the cataract cuts the Nile, and he saw something Mari-Nuba had not: that the Pride's future would not be found on the river.
He opened contact with the caravan cities of the western desert, sent the first Pride envoys across the Sahara by the old oasis roads, following the old Savanna Road of Dedun-Meri where it still ran. He found small circles of watchers in the Sahel who had kept the old lion songs alive for centuries without ever hearing from the Nile. They had no Roll, but they were ready to learn it.
He did not live to see the crossing. But when the first Maahes of the next age took the Roll to the Sahel, they walked the road he had mapped.
What he left behind: the first western routes, and a promise from the Sahel that it would be ready to receive the Roll.
