Nightsider have their origin on Krrendar IV, but were evacuated when the planet became uninhabitable by environmental pollution and robber economy. They relocated to New Krrendar where they live to this day.
Nightsiders are dark-furred, nocturnal bipeds, averaging about 1.4 meters in height. They are neither robust nor athletic, furthermore they suffer from amblyopia. In exchange they are keen-eared. As their complexion is similar to "rats" (rodents from earth) they are often insulted by calling them "ratface".
Nightsiders are asexual and reproduce by parthenogenesis. They release huge quantities of "seeds" into the oceans of the worlds they've settled, seeds which hatch into non-sentient tadpole-like aquatics that roam the oceans. Nightsiders only take interest in their "children" once they've emerged from the waters and metamorphosed into full-fledged adults.
Because of their reproductive method, Nightsiders have no real connection to their parents. They have no permanent mates. As hatchlings, they literally eat their own siblings to survive. As a result, their society is ruthlessly competitive, with little or no check on even the most despicable behavior.
Now that their world has been ceded to the Pyrians (who found most of their "pyraforming" work had already been done for them), Nightsiders have dispersed themselves throughout known space. While some have prospered in their new environments, many Nightsiders remain at the margins of Commonwealth society, a problem our best social scientists are working to alleviate.
