Niacin

The Niacin are a winged humanoid species.

They resemble humans, but had different nasal pasages and butterfly-like wings. Some were capable of flying with their wings, while an occasional genetic mutation has caused some not to develop wings. Their homeworld was soon depleted of natural resouces, spuring a massive exodus from the planet. They were taken in by the Terran Federation, who allowed them to settle first on outer colonies such as Proctor.
