The Greenwall is a major mountain range in western Hellea. The mountains have been eroded by time, the formerly sharp peaks ground down by wind and water. Most of the Greenwall is covered by dense forests, inhabited by a wide array of wild creatures both mundane and magical.
The Greenwall has few permanent inhabitants aside from some small tribes of centaurs. At one point the strix of Corax evidently lived in the region, and ancient ruins attest to this past.
