Hmmmm.....there were once five races who existed in that state...two have since passed on into memory, obliterated by natural disasters before they could achieve spaceflight. One, the Zentrisi, exists as a peaceful race of scholars and thinkers. They would not be there. The last two though.....the Traghari and the Svuitu. The Traghari tend to keep to themselves and, while they will do evil deeds, they wouldn't be serving Satan. The Svuitu would. They are an old, very nasty and very disagreeable race, always a menace to those unfortunate enough to encounter them. Their fluidic crystalline makeup makes them supremely adept at concealment and silent strikes, but renders them physically weak. Because of this, they've concentrated on beam and projectile weapons, and have produced some fearsome designs. Their weapons are not to be trifled with.
