...It is not known how far these forests extend. It is not impossible that they belt the land surfaces of the planet. They begin near the shores of Thassa, the Sea, in the west. How far they extend to the east is not known. They do extend beyond the most northern ridges of the Thentis Mountains.

The Laurius is a winding, long, gentle, slow river. It does not have the breadth and current which are the terrors of the titanic Vosk farther to the south, well below Ko-ro-ba, though well above Ar, which is said to be the greatest city of all known Gor. The Laurius, like the Vosk, flows in a generally westernly direction, though the Laurius inclines more to the southwest then the great Vosk.
