Ieleen was a mage and the navigator of the Silver Dawn, a ship she owned with her husband, Jute Hernan. She was a Falaran from Walk and drew upon the warren of Ruse. Sometimes known as the "Seawitch", she was legendary for her "seeming miraculous intimacy with wave and channel" despite being blind. She tolerated Jute's restless curiosity even as she tried to steer him away from dangerous and illegal work, such as piracy.
Ieleen accompanied the Silver Dawn to the gold fields of Assail, where she used her powers to guide the ship through the difficult Fear Narrows. Once on the Dread Sea, she struggled to counteract the effects of the region's Omtose Phellack magic, exhausting herself and bringing her close to death. Ieleen ended the Kerluhm T'lan Imass siege of Mantle by calling down the winds of the north, alerting the Imass to the growing Jaghut magic there. When the Jaghut icewall threatened to overrun Mantle she took a shipload of the young and the wounded south while Jute stayed behind.
