Wren was born as the daughter of the Princess of the Elves and a Wing Rider. Because of the Elessedil and Ohmsford bloodlines mixing together, Wren was a distant cousin to Par Ohmsford, Coll Ohmsford, and Walker Boh. When Wren was young, her parents decided to return to Arborlon, which lay on the island of Morrowindl. They left Wren a bag of three blue stones, which in reality were the disguised Elfstones of the Ohmsford family. In addition, they made arrangements for Wren to be raised as a Rover, under the tutelage of the deaf and mute Garth. After several years of living with the Ohmsfords in Shady Vale, Wren went to live with Garth. Over the next several years, Wren became highly skilled in combat, tracking, and other Rover arts, and developed a close bond with Garth. Like Par and Walker, she also received dreams from the shade of Allanon. When Cogline came to collect her, she managed to discover that he had tutored Walker in the use of his magic. With Garth at her side, she came to the Hadeshorn, and received the charge to bring the Elves back to the Four Lands. To determine the location of the Elves, Wren sought the aid of the Addershag, a seer who told her how to gain aid from a Wing Rider. As she and Garth waited in the Wing Hove, they were attacked by a Shadowen, whom Wren destroyed with the now revealed Elfstones. Shortly after, Wren and Garth gained the help of the Wing Rider Tiger Ty.
