To the Spacers, the Diggers were familiar looking from old videos: they were rootstock humans such as populated the Epic. Genetically they were homogeneous. They were white people with blond or red hair, and eyes that seemed to have gone pale in the darkness of their caves. Their skin was fair by nature, but freckled by exposure to the aboveground sun. They were smaller than rootstock humans, but not so much so that any one of them would have seemed dwarfish on a busy street in the Chain. Except for Teklans and Neoanders, who had occupational reasons for needing to be large, the descendants of the Eves had also lost stature, particularly during the First Millennium. They had been slow to gain it back, even during the Fifth, when by and large they’d had plenty of room to stand up straight. These Diggers—at least the limited sample standing close enough for Ty to evaluate them—did seem uncommonly stocky, however.
