Msvokas

From publisher blurb: This installment of Star Log.EM includes: 1,000 words introducing the msvokas, a race of radioative, avianoid creatures that subsist completely on radioactive isotopes. Every few years, these nuclear beings must expunge the natural isotopic toxins that build up inside their bodies by rebirthing themselves much like the phoenixes of antiquity. Included is a plethora of information regarding their habits and culture, as well as racial traits for msvoka PCs and a new feat.
