What are Constellations?

The constellations are the first indication that the Queen of Darkness has come to Krynn. Raistlin notices that the Queen of Darkness and the Warrior of Virtue are both constellations missing from the night sky. At the end of the story, after they have killed Verminaard, Raistlin says that the constellation, the Queen of Darkness, has not returned to the sky and she has not yet been defeated.
