Many centuries prior to the 2370s, an advanced alien race known as Species 312 discovered that a majority of the population that was technologically advancing was polluting the area of a more primitive species that was their genetic ancestors, the Ventu. The aliens placed an energy barrier to act as a shield around the Ventu area, protecting them from the Ledosians. For centuries, the Ledosians had tried everything to penetrate the field without success. The alien-unicorn design on the Ledosian badge is remarkably similar to that of the Mari's emblem.
