Paul Edwin Zimmer

Paul Edwin Zimmer (1943–1997), the brother of science fiction and fantasy author Marion Zimmer Bradley, was a noted poet and an established author in his own right. He was also an accomplished swordsman who studied both eastern and western schools of the martial art and brought much of this knowledge to the books he wrote.

He is best known for his Dark Border series – a set of 4 published books: The Lost Prince, "King Chondos' Ride, A Gathering of Heroes, Ingulf the Mad and one still awaiting publication, The King who was of Old. He also co-wrote The Blood of Colyn Muir with his foster brother Don Studebaker (who writes fantasy under the name of Jon DeCles) and Hunters of the Red Moon and The Survivors with his sister. He is also supposed to have collaborated with Bradley without credit on The Spell Sword and is rumored to have assisted his sister in the fight scenes in some of her other Darkover novels.
