The Sullen Gulf
Droyne are a Major Race inhabiting scattered worlds within an area slightly larger than the region of the current Third Imperium. The Droyne are a small race derived from winged herbivorous gatherers. They vary in size depending on caste but generally stand one meter tall (large workers and warriors can be larger than humans). The history of their evolution remains a puzzle because their home world is not known with certainty.
A Droyne society, be it large as a world or as small as an isolated enclave, is called an Oytrip. These oytrips are divided into rigid castes determined when an individual reaches adolescence. The six castes of the Droyne all serve different functions within Droyne society. Although identical at the time of caste selection, caste members develop pronounced physical and mental differences by maturity. Different genetic programs are awakened by differences in diet and environment among the various castes. Young leaders, for instance, experience a nearly 30 percent increase in brain size in the first year after casting; drones develop sexual organs; and so on.
