These little guys may be strangely well suited to a certain old RAFM range of figures..
THE SWIFT
Humanoid aliens of diminutive stature, often winged with reptilian features. Swift can exhibit a variety of characteristics but being a small, sentient species likely to have developed on worlds with large, powerful predators tends to give them a certain flighty and erratic demeanour.
They often follow a caste system with each member fitting into certain roles for which they have been raised their whole lives.
The Fringe
Nobody knows the origin of the small, winged lizards known commonly as "The Swift". Colonies of them can be found almost everywhere, usually in clusters of nearby worlds.
Researchers speculate that the colonies were originally founded as part of a galaxy spanning migration but the reasons, starting point or eventual origin is not known and the Swift themselves are not forthcoming with explanations, if they are even aware of them any longer.
Swift colonies tend to mind their own business though they are often attracted to archeological digs and ancient artifacts, causing conflict with explorers and treasure hunters.
