Wren Ohmsford, a descendant of the legendary Jerle Shannara, was charged by the shade of the Druid Allanon to travel to the distant island of Morrowindl and find the Elves to bring them back to the Four Lands.

Tiger Ty, the Wing Rider, carried Wren Ohmsford and her friend Garth to the only clear landing site on the island of Morrowindl, where the Elves might still exist.

Only the magic of the Loden keeps Arborlon safe, but its power is failing, and if the Elves are not returned to the Westland soon, they will not survive.

Upon reaching the Elves, Wren learns about her true Elven heritage, as her maternal grandmother is the current Elf Queen, Ellenroh Elessedil.

Tiger Ty gathers the small company and flees Morrowindl, where Wren restores Arborlon to its original location in the Westland.
