No one from Nether Norton has ever been out of the Vale, and the wide world seems terrifying to Will. Gwydion explains that he must leave the Vale for his own good. Twice he tries to run away and go home, but each time he is prevented by Gwydion’s magic, and eventually the wizard tells him they are being hunted by a fearsome enemy. At first, Will imagines it must be the Sightless Ones, the sinister fellowship of tax collectors who both squeeze the common people and engage in crooked politics with the lords of the Realm, but it soon becomes clear that a far more formidable foe is looking for them. Gwydion will drop only vague hints about this, but he says that Will is a ‘Child of Destiny’ – one whose coming has been foretold in the Black Book.
Soon they arrive at a gloomy tower in the depths of the Wychwoode, and there Will is lodged with the grotesque Lord Strange, a man who is afflicted by a vile spell and who wears the head of a boar. Gwydion leaves Will to live in the tower all summer long, and there he is taught to read and write. He also learns from the local Wise Woman something of the ‘redes of magic’ – these are curious rules that reveal the wisdom of the world and enable magic to be done. But Will’s spirit rebels against Lord Strange. He secretly looks in a forbidden book and reads certain spells, which he then uses for the unworthy purpose of trying to impress a pretty girl. What he attracts instead is the marish hag, a dangerous supernatural creature that inhabits the ancient wood. He is almost drowned by the hag, and only saved by Gwydion’s return.
But Will has also gained friends in the Wychwoode, among them the mysterious Green Man to whom he renders an unwitting service, and the girl, Willow, with whom he discovers Grendon Mill. This, it turns out, is Lord Strange’s secret armoury, where men have cut down the great oaks of a sacred grove to roast into charcoal so that weapons of war may be forged.
When Gwydion returns, he shows his great displeasure at Lord Strange’s activities. In turn, the hog-headed lord blames King Hal whose preparations for war are being fed by the mill. The wizard then leaves angrily, taking Will with him.
As they travel south Will is asked if he knows about King Arthur. He says he knows about him from old tales. Gwydion tells him that the tales about the sword in the stone speak about an Arthur who became king a thousand years ago, but that he was only the second incarnation of an original Arthur. That Arthur was an adventurer who lived in the time of the First Men in the far distant past, and travelled from the land of Albion into the Realm Below to bring out sacred objects known as ‘the Hallows’. Moreover, there is a prophetic verse that speaks of a third and final incarnation of Arthur…
Will begins to feel uncomfortable because it seems that the wizard is convinced that Will himself is that third incarnation.
Unfortunately, the prophecy is confirmed at every turn. At Uff, Will recognizes the White Horse, and stands upon the Dragon’s Mound where he experiences a vision of an army massing below. The earth yields up the gift of a horn to him, and in Severed Neck Woods Will is given the freedom of the wildwood by the Green Man himself.
They come at last to the royal hunting lodge of Clarendon, where Gwydion warns the weakling monarch, and asks for aid in a vital magical mission that will prevent the Realm from sliding into war. But the royal court is already deeply under the influence of the beautiful but greedy queen and her violent ally, Duke Edgar of Mells.
The queen is pregnant, and it seems to Will that Duke Edgar is the father. Will also suspects that the gentle king has been poisoned by them. And he notices a sinister figure lurking nearby, invisible to everyone but Will and the queen. Only later does he learn that this is the sorcerer, Maskull, Gwydion’s arch-enemy, who, among other things, is trying to find Will and kill him. Fortunately, Maskull does not realize Will is present, but even so events are about to take a turn for the worse. Gwydion’s request for royal aid is refused, and he is attacked by Duke Edgar, and forced to employ a powerful vanishing spell, which is accomplished only just in the nick of time.
Where Will and Gwydion vanish to is a sacred place, even by the standards of the Blessed Isle. They appear on cliff tops high above the sea, standing on the westernmost point of land in the whole world. Here Gwydion renews his strength and explains to Will about ‘the lorc’. This is a network of powerful earth streams that extend throughout the Isles. Long ago, he says, an array of standing stones was set up on these streams of power by an ancient race, the fae, who lived at the time of the First Men, but who long ago retired into the Realm Below. Each stone is filled with an immense quantity of harm.
According to the Black Book, these ‘battlestones’ were disposed across the Isles with the intention of repelling invasions. The fae believed that despotic sorcerers would one day arise in the Tortured Lands and begin to enslave men’s minds with a powerful idea called the Great Lie. In time the Isles themselves would face conquest, and their people, the First Men, would be enslaved – unless the lorc was erected as a defence. After much debate, the battlestones were wrought and put in place, and the secrets of the lorc bequeathed to the First Men when the fae withdrew.
For many centuries, the Isles remained free from interference. The Age of Trees passed into a second, lesser Age. Then the First Men failed, and the Isles became the haunt of giants and fire-breathing wyrms. When a third Age dawned, the Age of Iron, the hero-king, Brea arose and set foot upon the shores of Albion. He vanquished the giants and proclaimed the Realm, settling the land once again. After that the Realm went unmolested for eighty and more generations, until the time when, as the fae had foreseen, the Slavers’ power burgeoned in the east. By the time of King Caswalan, the sorcerers of the Tortured Lands had spread the Great Lie far and wide. They commanded huge armies, and made no secret of their desire to conquer the Isles. Their first coming, a thousand years after the landing of Brea, was repulsed. But soon afterwards the secret of the lorc was betrayed and its protective power undermined. The invading Slavers were then able to block the vital flows of earth power by building in stone. They shattered the Realm into many shards with their slave roads, and so the lorc was broken. But by Will’s time the slave roads are more than a thousand years old. Many have begun to fall into ruin, and the lorc, so long inactive, has begun to awaken…
Gwydion tells Will that he urgently needs to find and uproot the battlestones or there will be a bloodbath. Each stone will mark a place of great slaughter, and the ensuing chaos will enable Maskull to gain control of the mechanisms of fate. If Maskull is allowed to steer the Realm it will slide towards a devastating future – a future wholly without magic, and one in which strife and terror will reign for five hundred years.
Will and the wizard sail back from the Blessed Isle, and soon afterwards encounter a skeleton inside a yew tree. It is the remains of a lad Will’s age (and with a similar name) who has recently gone missing. He has been magically murdered. It is grisly evidence that Will is still being sought by Maskull. It cannot be long before he realizes that the wizard’s young bag-carrier is his quarry, and so Gwydion decides that Will must once more be lodged in a place of comparative safety.
Meanwhile, Gwydion makes absolutely sure that Will is Arthur’s third incarnation, by stirring up his latent magical talents and teaching him to ‘scry’. And so, using Will’s partly-fledged abilities and the wizard’s command of ancient lore they manage to locate their first battlestone, the Dragon Stone. As they dig it up, Will experiences for the first time the frightening mental disturbances caused when such stones are threatened, but eventually Gwydion wraps it in binding spells and they take it to a place where Gwydion thinks it may be temporarily stored.
Once at Castle Foderingham, the stone is carefully mortared into a dungeon under the keep – Gwydion hopes it will remain dormant there while he searches for further fragments of the Black Book in order to discover how to drain the stone of its harm. But the owner of Castle Foderingham is Duke Richard who, with some justice, considers himself to be the rightful king of the Realm. He has just discovered that his claim to the throne has been fatally weakened because the queen has at last given birth to a son. He is also already aware that the boy is not the king’s child, but fathered by Duke Edgar, who happens to be Richard’s political rival. Richard must do something about this, and soon. And
