The Hills of Nomen is a mountain range stretching from the (even more imposing) Icerime Peaks south to the Castrovin Sea. It creates a natural border between Iobaria and the nations of Brevoy and Galt.
Named by a fearful Taldan traveler, the Hills of Nomen are dangerous to wanderers who fail to heed the local inhabitants, for the hills are home to numerous centaur tribes who defend their territory fiercely. Other non-human races dwell here too, making travel across the rugged terrain dangerous at best, even along the ancient Koloran roads. A number of human armies have attempted to "stem the inhuman tides" only to be destroyed, their bones littering the hillsides.
