Hunfrid Dhotdruk, the explorer
"Hunfrid's studies on minerals and cave ecosystems are legendary. Before going full-time into exploring strange and dangerous caves and mines, he was the chief blacksmith in the city of Gludio, serving the noble families.
Requested by one of the nobles of the city, he was commissioned to find the vein or the origin of the rare green pearls that are often found by farmers accidentally. A very rare and expensive gemstone.
Motivated by finding the origin of the pearls rather than the reward and after testing them to find out their composition, he concluded that their origin is certainly not mineral, and there is evidence that they come from a certain area of the world, a cave system almost forgotten in current maps.
Having in mind the expected location, he left years ago escorted by the heir of the house Naugrim to ensure his safety and to keep the information he could find confidential.
They were never seen again and presumed dead years ago."
