MARS: THE SKULL OF A PLANET PICKED CLEAN BY THE WIND OF TIME

Beyond the desert of Meroe, past the ancient cliffs of the dust-locked continents, past the dry wharfs of a city that was old when Earth was new, the caravan crept into the unmapped waste called Umbra.

It was here that the outworlder Ryker followed the golden-eyed Valarda and found the Child-of-Stars.
