So yesterday I generated some random races on which to hang a campaign setting. They were the Jackalwere, beaver, sirine, ankheg, wererat, and satyr. Here goes:
Jackalwere and Wererats
These are the females and males of the same race. Their society is matriarchal and dominated by the Jackalwere, who select mates from the wererat populace. In order to breed, both must assume human form, though generally they appear as hybrids. They live in cities of pyramids, surrounded by moats. The Jackalwere inhabit the pyramids and the wererats live in the subterranean moats around them.
Sirine and Satyrs
The sirine inhabit reefs and kelp forests in off shore shallows, and like the Jackalwere and Wererats form a symbiotic relationship with coastal communities of satyrs, who provide them with "companionship" and breeding. Neither sirine nor satyr forms organised societies, preferring to live in relative anarchy.
Intelligent Ankhegs live in huge underground kingdoms deep underneath the thickest forests. They war constantly with all other beings, seeing them merely as food, and they cannot be communicated with - their language is composed entirely of posture and the release of hormones, which other races cannot emulate. Their culture and society is largely unknown.
Intelligent beavers inhabit lakes and rivers, creating huge riparian dam-cities. Surrounding these cities they tend huge areas of cultivated forest, so as to provide them with endless supplies of wood. This brings them into constant conflict with Ankheg interlopers who seek the loamy soil of these beaver-made forests.
I call this campaign setting "Symbiants and Also Beavers and Ankheg World". Or Sabaw for short.
