Wyvern Tor

This crag is a prominent landmark in the rugged hills northeast of the Sword Mountains, and is easily visible from twenty miles away. People traveling along the Triboar Trail in the vicinity of Conyberry catch glimpses of Wyvern Tor to the south as they go. The tor was formerly the home of a large and dangerous nest of wyverns, but a band of bold adventurers dealt with the monsters years ago. Though the wyverns never returned, other creatures lair here from time to time. 

On Uktar 13, 1491DR the heroes discovered a cave that was being inhabited by orcs from the many arrows tribe, lead by Brughor Axe-biter, when investigating on behalf of Sildar Hallwinter. The heroes defeated Brughor and his band, freeing Wyvern Tor of the threat from the marauding creatures.
