Terec and the Wall. Terec of Lund, #2

In the north of Ysthar, past the edge of the Empire of Astandalas, there is the tundra, and beyond the tundra, the great wall of ice. No one goes there, save for a few hunters after mammoth ivory or furs, unless it is to look upon the Ice and then, suitably impressed, turn back to be awed by the wall of magic that is the border of the Empire. But there are those for whom the Wild is not only out there but a magic within their blood, and for them--or at least for Terec, once of Lund and now only of the wastelands--the Ice is a wall that might, perhaps, contain a door ... Book 2 of Terec of Lund, to be read after Terec and the Wild.
