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.
