Echoes of the Thousand Year War
Wyvern Tor was a crag in the hills northeast of the Sword Mountains, and was easily seen by any on the Triboar Trail near the vicinity of Conyberry.
Wyvern Tor was formerly inhabited by a vicious nest of wyverns, but they were slain by bold adventurers. By the time of approximately 1480 DR, the place was abandoned by the wyvern nest. Many creatures laid here from time to time, the most prominent of which was a group of orcs and one ogre.
In 1480 DR, the place became the lair of orc scouts of the Many Arrows tribe. The stories of Phandalin being resettled in this time renewed traffic on the Triboar Trail and attracted the orcs to the area.
