Venus is a primitive world. But on Mars, early hominids evolved civilization earlier than their earthly cousins, driven by the needs of a harsh world growing still harsher as the initial terraforming ran down. Without coal, oil, or uranium, their technology was forced onto different paths, and the genetic wizardry of the Crimson Dynasty united a world for more than 20,000 years.

Now, in a new stand-alone adventure set in this world's AD 2000, Jeremy Wainman is an archaeologist who has achieved a lifelong dream: to travel to Mars and explore the dead cities of the Deep Beyond, searching for the secrets of the Kings Beneath the Mountain and the fallen empire they ruled.

Teyud Zha-Zhalt is the Martian mercenary the Terrans hire as guide and captain of the landship Intrepid Traveller. A secret links her to the deadly intrigues of Dvor il-Adazar, the City That Is a Mountain, where the last aging descendant of the Tollamune Emperors clings to the remnants of his power...and secrets that may trace their origin to the enigmatic Ancients, the Lords of Creation who reshaped the Solar System in the time of the dinosaurs.

When these three meet, the foundations of reality will be shaken - from the lost city of Rema-Dza to the courts of the Crimson Kings.
