You push open the iron door and gingerly explore the passageway beyond. It runs from the dock where your adventure began, to a small chamber carved from the rock. Although the sunlight from the dock is bright, it only penetrates about half-way along this passage - as the sunlight grows fainter, most of the illumination comes from wall lights that cast dim pools of radiance toward the floor.
You may:
Enter the chamber or
Retreat to the dock.
