The Alliance

The Alliance is unique in the Strange Stars in representing interspecies cooperation on an interstellar scale. It was formed by seven peoples displaced by the Great Collapse. Initially distrustful of each other, they came to fear the lawlessness of the Zuran Expanse and religious strife in the center of the Radiant Polity more than sacrificing a bit of their own sovereignty.

Previously, we've touched on the smaragdines, the blesh and the gnomes.  Here's an overview of the other Alliance members:

The hyehoon are humanoids spliced from avian and hominid DNA. They have lighter frames than humans, but are strong for their weight. Hyehoon are a dynamic and inquisitive culture, producing explorers, scientists, diplomats and traders. They face internal strife from conflict with the minority religious faction known as the Eden Seekers.

The neshekk banking and investment clans are the financial backbone of the Alliance. Neshekk are greatly concerned (possibly obsessed) with security and privacy. They never go into public without their elaborate privacy screeens/firewalls called nizara in place. Off-worlders are restricted to certain areas of Kuznuh, the neshekk homeworld, and it is a misdemeanor to view any public space unfiltered by the metascape.

The Alliance's greatest warriors are the thrax. A clone race, created for war, they still structure their society along martial lines. They are known for their elaborate battle armor and their enthusiasm for hand to hand weapons.

The winged deva are the most mysterious of the Alliance's members. They can survive in hard vacuum unprotected and through space under their own power (at least for short distances). In their home system of Altair, they're repairing damaged moon-sized brains.
