Dungeons & Dragons 5th Edition Intro Campaign
This particular crag is visible for twenty miles in most directions, meaning that it serves as a useful landmark for orienting oneself while traveling along the Triboar Trail. Its name derives from the fact that it once served as the roost for a large nest of particularly mean-spirited wyverns, which have since been driven off by adventurers. While wyverns are no longer a threat in the area, other monsters have periodically decided to make their homes here.
A Wyvern, for reference.
