From the introduction:
The story of Ironwood was once common among the superstitious. A power-mad king, a betrayed monk, a library of evil magic, and more... a story grandfathers told children to thrill and scare. But that was long ago. Grandfathers no longer tell those stories. Children no longer beg to hear them.
A reference in an ancient book, a drawing and a tale, leads you to Ironwood. Distant from civilization, halfway up an unnamed mountain, you stand in front of walls long-unseen. Up here, the air is thin. The world is quiet. No buildings cluster near the keep. Yet the castle itself still stands.
The tales are too long forgotten to restore, yet something remains. Adventure well. Those who survive will be forever changed.
A solitaire adventure for low-level characters.
