High above the town of Nuxvar, where the winds howl through the peaks of the Iron Mountains, lies the infamous Iron Pass—a treacherous, windswept road carved into the rock by ancient hands. Traders and travelers brave its heights for the promise of safe passage between valleys, but few linger near the Iron Henge, the enigmatic structure that crowns the pass.

A ring of towering, weathered monoliths forged from a metal unknown to any smith, the henge is said to be a doorway to another plane. On moonless nights, strange lights shimmer between the stones, and those who have stepped too close have vanished without a trace. Some return days later, raving of cities of glass and endless storm-lit skies, while others are never seen again.
