Leaving the city behind they worked their way north-west along the river valley, the companions taking turns to drive the carriage, ride the spare horses, or to walk alongside. After some days they came to another much reduced city straddling the river. From here they turned north, following a good Carthaginian road that crossed higher ground. Although this was early summer it felt markedly colder here than at the coast, and the land seemed even more barren, the towns and way stations burned out and abandoned. Avatak felt exposed without the guard, but there seemed to be no bandits on this empty tabletop of a country, and they made good progress.

They came to yet another city, another shrunken remnant. As they approached they came across a substantial procession forming up at the southern gates, men, women, children and old folk, most on foot, some dragging carts, evidently preparing to take the opportunity of the summer to head south. Avatak silently wished them luck.

At the gate Pyxeas’ party was challenged by a different kind of authority. This, it seemed, was the boundary between the Carthaginian empire and the realm of the Franks, whose power base was further north. Guards at the gates asked for hefty tolls to allow this Carthaginian party to pass. They had some Prankish money, but the Franks preferred Northlander scrip, which made Pyxeas laugh. ‘Just pay the man, Avatak, pay the man.’

North of the city they followed rougher tracks. The country was barren and bare, and grew steadily colder. In places they threaded through broad mountain passes; the mountains were all white-capped, and streaked with the grey tongues of glaciers. When they stopped on scraps of higher ground they would sometimes glimpse structures in the distance, not on peaks but on high plateaux, lines and rings of stone. These did not impress Avatak much until the road took them close to one of them, and the Coldlander was able to appreciate the sheer size of the stones, the vastness of the layout, and the careful precision with which it seemed to have been designed. But even these great sky temples were disused now, and the tracks that criss-crossed the complexes were covered with blown dust.

On they journeyed, descending at last from the higher ground towards the coast. Ibera was a great peninsula, Pyxeas said, with its neck crossed by a tremendous mountain chain – and now, from higher ground, Avatak could glimpse those mountains marching into the distance. They skirted that mountain chain, passing west by the coast of the Western Ocean, and they entered Gaira.
