The hill was mostly scrubby moorland of heather and bracken. It was full of wildlife, which had learned to live without the fear of man. Rabbits sniffed at my ankles and the cows and sheep paid me little or no heed as I walked past in the warm summer air. After an hour’s climb up the hill the moor led down to a small lake. I trotted down the slope and walked around the water’s edge, peering at the fish in the clear waters and wondering what a loss this vast natural wildlife park would be when Maltcassion had gone. I knew from my geography classes that the lands covered an area of 350 square miles, slap bang in the disputed borderlands between the Kingdom of Hereford to the east and the Duchy of Brecon to the west. I reached the far side of the lake, walked through a spinney of silver birches and then climbed another hill from where I could see deep into the Dragonlands. It was a landscape without electricity pylons, buildings or telegraph poles. There were no roads, no railways, and no people. The vegetation had grown unchecked for centuries, and large oak forests covered half the area. The land was free and clear and seemed to stretch away for ever. It would take me a long time to explore it but I was in no hurry. In fact, if I were lost for a week it would be to Maltcassion’s distinct advantage.

I ran down the short slope and walked by a stream whose clear waters babbled excitedly about the rocks. Presently I came across a crashed aircraft. The loss of this particular aeroplane in fog one snowy night ten years previously had shown that the force-field was shaped like a dome with its highest extremity at five thousand feet. Only the very brave or the very stupid would dare to fly above the lands, as an engine failure would spell certain death. I looked into the plane; it was empty. The pilot and passengers would have been vaporised as the small craft came within the marker stones’ influence.
