On a visit to Stonehenge you find yourself fascinated by the mystery of this ancient monument. In your eagerness to get a closer look you stumble and bang your head on one of the stones and black out. Many hours later you wake and climb to your feet. A gasp escapes you as instead of the familiar sight of Salisbury Plain you find you are on a strange hill-top.

Thoughts of how you got here quickly turn to thoughts of how you get back. This is where I am afraid I must leave you. Good luck!
