There was once a young man who wished to gain his Heart's Desire.

And while that is, as beginnings go, not entirely novel (for every tale about every young man there ever was or will be could start in a similar manner) there was much about this young man and what happened to him that was unusual, although even he never knew the whole of it.

The tale started, as many tales have started, in Wall.

The town of Wall stands today as it has stood for six hundred years, on a high jut of granite amidst a small forest woodland. The houses of Wall are square and old, built of grey stone, with dark slate roofs and high chimneys; taking advantage of every inch of space on the rock, the houses lean into each other, are built one upon the next, with here and there a bush or tree growing out of the side of a building.

There is one road from Wall, a winding track rising sharply up from the forest, where it is lined with rocks and small stones. Followed far enough south, out of the forest, the track becomes a real road, paved with asphalt; followed further the road gets larger, is packed at all hours with cars and trucks rushing from city to city. Eventually the road takes you to London, but London is a whole night's drive from Wall.

The inhabitants of Wall are a taciturn breed, falling into two distinct types: the native Wall-folk, as, grey and tall and stocky as the granite outcrop their town was built upon; and the others, who have made Wall their home over the years, and their descendants.

Below Wall on the west is the forest; to the south is a treacherously placid lake served by the streams that drop from the hills behind Wall to the north. There are fields upon the hills, on which sheep graze. To the east is more woodland.

Immediately to the east of Wall is a high grey rock wall, from which the town takes its name. This wall is old, built of rough, square lumps of hewn granite, and it comes from the woods and goes back to the woods once more.

There is only one break in the wall; an opening about six feet in width, a little to the north of the village.

Through the gap in the wall can be seen a large green meadow; beyond the meadow, a stream; and beyond the stream there are trees. From time to time shapes and figures can be seen, amongst the trees, in the distance. Huge shapes and odd shapes and small, glimmering things which flash and glitter and are gone. Although it is perfectly good meadowland, none of the villagers has ever grazed animals on the meadow on the other side of the wall. Nor have they used it for growing crops.

Instead, for hundreds, perhaps for thousands of years, they have posted guards on each side of the opening on the wall, and done their best to put it out of their minds.

Even today, two townsmen stand on either side of the opening, night and day, taking eight-hour shifts. They carry hefty wooden cudgels. They flank the opening on the town side.

Their main function is to prevent the town's children from going through the opening, into the meadow and beyond. Occasionally they are called upon to discourage a solitary rambler, or one of the few visitors to the town, from going through the gateway.

The children they discourage simply with displays of the cudgel. Where ramblers and visitors are concerned, they are more inventive, only using physical force as a last resort if tales of new-planted grass, or a dangerous bull on the loose, are not sufficient.

Very rarely someone comes to Wall knowing what they are looking for, and these people they will sometimes allow through. There is a look in the eyes, and once seen it cannot be mistaken.
