Duke Lohearn Mantawu (pronounced low-HURN MAN-tah-woo), called Topabaw (TOP-ah-bahw), was the feared luarin spymaster of the Copper Isles. He served House Rittevon from an unknown date to his death in 463 HE, when he fell from grace. His nickname was an allusion to his ability to inspire and create fear throughout the Isles.
