In The Summer Tree it was told how Loren Silvercloak and Matt Sören, a mage and his magical source from the High Kingdom of Brennin in the world of Fionavar, induced five people from our own world to “cross” with them to Fionavar. Their ostensible purpose was to have the five participate in the festivities attendant on the celebration of the fiftieth year of the reign of Ailell, the High King. In fact, there were darker premonitions underlying the mage’s actions.

In Brennin, a brutal drought was afflicting the kingdom. Ailell’s older son, Aileron, had already been exiled for cursing his father’s refusal to allow him to sacrifice himself on the Summer Tree in an effort to end the drought.

In Fionavar, the five strangers quickly found themselves drawn into the complex tapestry of events. Kim Ford was recognized by the aged Seer, Ysanne, as the successor she had prophetically dreamt. Kim was initiated into the knowledge of the Seers by the water spirit, Eilathen, and presented with the Baelrath, the “Warstone” that Ysanne had been guarding. Kim was also shown the Circlet of Lisen, a gem that shone with its own light. The beautiful Lisen, a power of Pendaran Wood, had been the magical source and the beloved companion of Amairgen Whitebranch, the first of the mages. She had killed herself, leaping into the sea from her Tower, upon learning that Amairgen had died. Ysanne told Kim the prophecy that accompanied the Circlet: “Who shall wear this next, after Lisen, shall have the darkest road to walk of any child of earth or stars.” Later, as a last gesture of ultimate sacrifice on the eve of war, Ysanne, knowing Kim would have need of the old Seer’s power in the days to come, used Lokdal, the magic dagger of the Dwarves, to kill herself—but not before tracing a symbol on the brow of the sleeping Kim, which action enabled her to make of her own soul a gift for Kimberly.

Meanwhile, Paul Schafer and Kevin Laine were initiated in quite a different way. Paul played—and lost—a night game of chess with the High King in the palace of Paras Derval, during which an unexpected bond of sympathy was forged between the two. The next morning he and Kevin joined the band of the reckless Prince Diarmuid, Ailell’s younger son, in a raid across the River Saeren to Cathal, the Garden Country. There, Diarmuid achieved his intended seduction of Sharra, the Princess of Cathal. After the company’s return to Brennin, they passed a wild night in the Black Boar tavern. Late at night a song Kevin sang reminded Paul too acutely of the death in a car accident of Rachel Kincaid, the woman he had loved. Paul, blaming himself for the accident, which had occurred moments after Rachel had announced she was going to wed someone else, took a drastic step: he approached the High King and received Ailell’s sanction to sacrifice himself in the King’s stead on the Summer Tree.

The next night, the glade of the Summer Tree in the Godwood saw an epic battle. As Paul, bound on the Tree, watched helplessly, Galadan the Wolflord, who had come to claim Paul’s life, was opposed and driven back by a mysterious grey dog. The following night—Paul’s third on the Tree—a red full moon shone in the sky on a new moon night, as Dana, the Mother Goddess, granted Paul release from his guilt, by showing that he had not, in fact, subconsciously willed the accident that had killed Rachel. As Paul wept, rain finally fell over Brennin. Paul, though, did not die. He was taken down from the Tree alive by Jaelle, the High Priestess of Dana. Henceforth Paul would carry another name: Pwyll Twiceborn, Lord of the Summer Tree.

By now it was clear that an epochal confrontation was at hand: Rakoth Maugrim, the Unraveller, defeated a thousand years before and bound under the great mountain, Rangat, had freed himself and had caused the mountain to explode with a hand of fire to proclaim that fact.

His freedom was to have immediate consequences for Jennifer Lowell, the fourth of the strangers. In Paras Derval she had witnessed an unsettling incident during a children’s counting game. A young girl, Leila, had “called” a boy named Finn to “take the Longest Road” for the third time that summer. No one, not even Jaelle, who had also been watching, knew exactly what that meant, though Jaelle was quick to enlist Leila as an acolyte in the Temple. The next day, riding outside the town walls, Jennifer met Brendel of the lios alfar—the Children of Light—and a party of his people. She spent the night in the woods with them, and in the darkness they were attacked. Concerned about the arrival of the five strangers, Rakoth Maugrim had Galadan and Metran—the traitorous First Mage of Brennin—abduct Jennifer. She was bound to the back of the black swan, Avaia, and borne north to Rakoth’s fortress of Starkadh.

Meanwhile, the terrifying explosion of the mountain had caused the death of the aged High King. This led to a tense confrontation between Diarmuid and his brother, Aileron—who had been disguised as Ysanne’s servant since his exile. The potentially violent situation was ended by Diarmuid’s voluntarily relinquishing his claim to the throne, but not before he’d received a knife in the shoulder, courtesy of Sharra of Cathal, who had come to Brennin to seek vengeance on him for the deception that had led to her seduction.

In the meantime, Dave Martyniuk, the last of the five strangers, had been separated from the others in the crossing to Fionavar. He ended up far to the north among the Dalrei, the “Riders,” on the Plain, and found himself drawn into the life of the third tribe, led by Ivor, their Chieftain.

Ivor’s young son, Tabor, fasting in the forest for a vision of his totem animal, dreamt a seemingly impossible creature: a winged, chestnut unicorn. Three nights later, at the edge of the Great Wood, Pendaran, he met and flew upon this creature of his fast, Imraith-Nimphais—a double-edged gift of the Goddess, born of the red full moon.

Meanwhile, Dave was escorted toward Brennin by a party of Dalrei led by Ivor’s older son, Levon. The company was ambushed by a great number of the evil svart alfar, and only Dave, Levon, and a third Dalrei, Tore, survived by riding into the darkness of Pendaran Wood. The trees and spirits of Pendaran, hating all men since the loss of the beautiful Lisen of the Wood a thousand years before, plotted the death of the three men, but they were saved by the intervention of Flidais, a diminutive forest power, who claimed, among other things, to know the answers to all the riddles in all the worlds, save one: the name by which the “Warrior” could be summoned. As it happened, the search for this name was one of the tasks Ysanne had left with Kimberly.

Flidais sent word to Ceinwen, the capricious, green-clad goddess of the Hunt, who had taken a special liking to Dave. The goddess arranged for the three friends to awaken safely on the southern edge of the Great Wood in the morning.

She did more. She also caused Dave to find a long-lost object of power: Owein’s Horn. Levon, who had been taught by wise old Gereint, the blind shaman of his tribe, then found the Cave of the Sleepers nearby—a cave wherein Owein and the kings of the Wild Hunt lay asleep.

The three friends rode south with this knowledge to Paras Derval, in time to arrive for the first council of Aileron’s reign. The council was interrupted twice. The first time, by the arrival of Brock, a Dwarf from Banir Tal who knelt before Matt Sören—once King of the Dwarves—and proffered the terrible tidings that the Dwarves, under the leadership of two brothers, Kaen and Blod, had helped the Unraveller to free himself by treacherously breaking the wardstone of Eridu, thus preventing any warning of Rakoth’s stirring under the mountain. They had also found and delivered to Rakoth the Cauldron of Khath Meigol, which had the power to raise the newly dead.
