Dragons of Autumn Twilight ended with the refugees from Pax Tharkas having found a refuge in a mountain pass in the hope of (possibly) making it through the winter. The second book in the Dragonlance Chronicles series begins with the Heroes of the Lance having already gone on another adventure, and having brought the refugees to the Dwarven city of Pax Tharkas. In the roleplaying game modules, your player characters would have gone through this story. However, while much of the Dragonlance modules were adapted to the original Chronicles series, not all of them were. In the late 2000s, Margaret Weis and Tracy Hickman returned to Dragonlance to adapt this missing chapter into novel form.
