The Dawning
In "The Dawning of a New Age" (1996), the first book of the series, Jean Rabe indicates that Goldmoon appears as an illusion to Dhamon Grimwulf, a former Knight of Takhisis, summoning him to the Last Heroes' Tomb, the tomb where the heroes of the Chaos War are kept. The author gives the reader, at that point, the guidelines for Dhamon's mission throughout the trilogy.
