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 return them to the Four Lands. The catch was that not one Elf had been seen in the Four Lands for more than a hundred years. No one in the Westlands knew of them---except, finally, the Addershag, who told Wren how to locate one.
