Many of Wrightson's books draw on the same body of Australian aboriginal mythology as Balyet does. The trilogy of The Ice is Coming, The Dark Bright Water, and Journey Behind the Wind features other legendary creatures, such as the ninya or ice people. Moon-Dark, like Balyet, builds a haunting and mystical spirit world in a remote landscape. Balyet tells a unique story, however; there is no carryover of characters or time-lines from the other books.
