This is a Tunnels and Trolls adventure in the Castle Calahony series.

The baron has the army march up the mountain. One of the scouts sent out a few days before, detected a wide entrance, guarded by a tower. A company of city orcs marches ahead and assaults the tower. It takes a few hours of heavy fighting.

When your company marches in, the tower has been reduced to a mere ruin. Fallen bodies have been shoved aside. Once in the cave, every patrol chooses his own way. The caves are immense.

You arrive at a crossing.
