A smoky, dangerous, and loud world unto itself, the House Tharashk refinery looms over Graystone. The orc Durgran’Torrn oversees the refinery’s workers, who process dragonshards extracted from Xen’drik’s interior. From the small Tharashk enclave attached to the refinery, Kurn d’Velderan leads the house’s operations in the city: directing Durgran, hiring out inquisitives, and running mining camps beyond the city’s borders.
