Of Kings and Dragons
A valuable and unusual type of gemstone deposit lies embedded in a series of f lint and sandstone cliffs in the far east of the Thanelands. Named Thrain sunstones after the prospecting explorer who discovered them, the gemstones found here glow with a warm, natural yellow light, and the subtle differences in the way light scatters from the stones allow the knowledgeable to determine which direction is north. Small, inferior stones glimmer like small candles, while larger, high-quality stones glow with the bright radiance of a well-made lantern. Jewelry set with Thrain sunstones fetches a high price in marketplaces all over the Inner Sea. Even badly chipped or cracked stones are valuable to those in need of a waterproof light source. The region, however, is a hunting ground for a large group of trolls, including a significant number of rock trolls that seem inexplicably drawn to the area. Those who wish to dig for sunstones are advised to be extremely stealthy and not to tarry, especially at nighttime when rock trolls stalk the cliffs. Thrain himself was certainly not immune to this threat, for he was killed and eaten by trolls on his return trip to the cliffs.
