The Crescent Forest lies along the southern curve of the Stormclaw Mountains. This thickly forested expanse is the most fertile and well-watered area in the Ivory Triangle and perhaps in the entire Tyr Region (aside from the Forest Ridge). During the months of Sun Descending, rain in the Stormclaw Mountains waters the forest with runoff. During the dry season, deep springs scattered throughout the easterly foothills sustain the area. The forest is thickest in the south and center; it thins considerably in the north because of logging from Nibenay and the dry winds blowing through Bremil Pass.

At one time, the Crescent Forest might have extended the entire length of the verdant belt, but no one can say for sure. The recent history of the forest has been shaped by the centuries-old rivalry between Nibenay and Gulg; the hunters of Gulg skirmish frequently against Nibenay’s foresters. For now, the judagas of Gulg keep Nibenay’s lumber camps limited to the northern end of the forest, but the increasing scarcity of wood in the Tyr Region—and the corresponding value of large logs—lures the woodcutters deeper into the forest.
