The sociology of Aesgar is uniquely diverse yet uniform. The majority of sentient beings in the galaxy are of humanoid stock, save a few instances of more bestial forms. Culturally the differences may be significant, but physically the characteristics of many humanoids are strikingly similar. The exact reason for the similarity in humanoid life is often attested to the very specific environments in which they can evolved and thrive. But the genetic similarities in many are difficult to ignore; some more radical scientists believe that interstellar travel was more advanced and widespread in the time before Terra Nova’s Unification, and that the seeds of human civilization spread in that time.
