Mythic Vistas: The Black Company Campaign Setting - Robert J. Schwalb, Owen K.C. Stephens I've been a fan of Cook's since I picked up a used copy of the SF Book Club's omnibus edition of The Black Company novels for $5.

A medium that brought together all of the novels was another "dream come true" and an irresistible lure. The designers also created a magic system that faithfully reproduces Cook's.
