This mining operation in the mountains of northern Zilargo is a collaboration between House Kundarak, Clan Mroranon (possibly the best miners and smelters in Khorvaire), House Tharashk (which found the site in the first place), and House Sivis (which handles relations with the Zilargo government). This mine extracts pure platinum from veins more than a mile below the surface. Clan Mroranon’s smiths make ingots of the platinum bullion, which House Kundarak uses as internal currency when transferring wealth from a Kundarak bank to a national government or to another Kundarak bank. Security is omnipresent, both to prevent theft by surface dwellers and because the miners sometimes disturb monsters from the depths of Khyber.
