It is a herd of northern tabuk," said Samos, "a gigantic herd, one of several. The herd of Tancred winters in the rims of the northern forests south and east of Torvaldsland. In the spring, short-haired and hungry, they emerge from the forests hind migrate northward." He indicated the map. "They follow this route," he said, "emerging from the forest here, skirting Torvaldsland here, to the east, and then moving west above Torvaldsland, to the sea. They follow the shore of Thassa north, cross Ax Glacier here, like dark clouds on the ice, then continue to follow the shore north here, until they then turn eastward into the tundra of the polar basin, for their summer grazing. With the coming of winter, long-haired and fat, they return by the same route to the forests. This migration, like others of its kind, occurs annually."
