Publication history
TSR released Forgotten Realms, the new campaign setting for Dungeons & Dragons, in 1987, and provided various marketing and promotional crossovers, including several lines of paperback novels. The first of these was the three books of the Moonshae Trilogy by Douglas Niles:  Darkwalker on Moonshae (May 1987), Black Wizards (April 1988), and Darkwell (February 1989). Niles followed these with another three books in 1992–1993, the Druidhome Trilogy. Reception
In the Io9 series revisiting older Dungeons & Dragons novels, Rob Bricken commented that "Like Darkwalker on Moonshae, Black Wizards is better written than some of the Dungeons & Dragons novels I've revisited on a technical level, but it doesn't have the focus of the first novel. As a result, it made me simultaneously angry and sleepy, which is sort of an impressive feat, but not one I feel interested in rewarding. So Black Wizards rolls a 4 on its 1d20, a point less than Darkwalker on Moonshae, but it should feel lucky I didn't make it roll with disadvantage. Seriously, this book made me very, very grumpy."
