Thirty-five miles east of Fort Valiance, the Aldwyn River flows with exceptional clarity through a region where ore from Ironholt's mountains has been processed into wealth for seven generations. Crystal Mills takes its name from the river's unusual purity — water so crystalline that you can see the stone bottom at depths of thirty feet, yet cold enough to power the relentless machinery of industrial transformation.

The town hosts approximately six hundred souls, yet its true importance lies not in numbers but in function. Every bar of worked metal that flows from Ironholt into the broader Morgath economy passes through Crystal Mills' transformation. The smelters, the mills, the assayers — this town extracts its proportion from every transaction, a tax paid in metal and coin for services deemed essential.
