Gilliand

The Gilliands were a sentient species of females native to the waterworld of Crul, where they evolved alongside the all-male Crolutes. Gilliands were taken as prize mates by the males, who filled harems and mansions with Gilliand wives and concubines.

Biology and physical appearance
The Gilliands were an all-female species which evolved alongside the all-male Crolutes on the waterworld of Crul. The two species were capable of mating, though reproduction only resulted in male Crolutes and female Gilliands.

Behavior
Gilliands lived in colonies on the beaches of Crul, and were competed for as mates by the Crolutes, who evolved a sex drive that made them aggressively pursue members of the female species to dominate them. A single virile Crolute could impregnate an entire Gilliand colony during the mating practices descended from the summer mating seasons of the Crolute precursor species. The females served as wives and concubines in sprawling harems and mansions owned by dominant males. Rey wondered if the separation of sex by species left Gilliands as misandrists and Crolutes as misogynists.

History
Having evolved alongside the Crolutes on Crul, Gilliands were competed for and dominated as mates, and were kept as wives and concubines in Crolute harems and mansions to breed new Gilliands and Crolutes.

Prior to leaving Crul, the Crolute Unkar Plutt mated with several Crolutes, but found Humans more attractive. He challenged other Crolutes for the favors of prized Gilliands, and built up a sizable harem of Gilliand concubines in his mansion before a failed business deal forced him to leave his homeworld.
