Before the Darkest Hour
The Nath, an upland basin of gentle hills in the northeast corner of Halruaa, is known for its herds of wild rothé and auroch, both of which are raised for food. Considerably higher in altitude than most of the rest of the country, this area boasts a slightly more temperale climate. The lower reaches are filled with mazes of ironwood trees left to grow unchecked by the local populace.
Perhaps the most significant features of the Nath Valley are the temples situated on the lower slopes of the mountains that surround the valley. Each of these temples focuses on one school of arcane wizardry above the others. The sects are small because while most in Halruaa profess at least a passing devotion to Mystra or Azuth, few feel the need to cement their connections to the divine through ceremony. The clerics and wizards who tend the temples are the few who have been called to serve the deities of magic in a more formal way.
Other than the temples, the valley holds little of significance. The Nath is a rugged, wild country compared to the rest of Halruaa, and those who live here must be prepared for threats from many directions, though by far the greatest threat comes from the east. Crinti riders occasionally sneak through the Nath Pass to harass the herders or raid the temples in the hills. Sizable Crinti forces have invaded this area on more than one occasion, but the powerful magic of the Halruaan aristocracy has always forced them back before they could get much beyond the mouth of the valley. Even so, the folk who by proximity serve as a first line of defense remain ever-watchful for the gray-skinned riders.
