Galactic 4th Edition
The Vryloka (vrī-lōkä) are a race of noble humanoids from Vryka V. Viewed as weak by some species, they have actually perfected politics, espionage, and stealth because of this.
The Vryloka are descendants of a humanoid shape-shifting race, possibly from Pahlus, that were driven off from their home-world, possibly for not being as well adept at shifting as others. For one reason or another, they made Vryka V their new home. However, the proximity of the Vryka system to Forbidden Space caused changes to occur to the race. Over the generations, their life forces were slowly drained by the dark energies nearby. This eventually created a society that could not make war, and instead they made territorial and resource claims via politics, hence the noble air about them.
