Centaurs

Before the onset of the Zoir war 10,000 BC, the Atlantian Empire had helped formed a large alliance with most of its rival states in the area, as a defense against such an invasion like the Zoir. One of the closest allies with Atlantis were the Centaurs, a half-humanoid/half-horse species who could live for a millennia. When their homeworld was destroyed, many of them wound up on the Atlantian homeworld before it was destroyed. Many of those that did ended up being put onto the colony ships that were meant to preserve the Atlantian people.

While Greek myths usually portrayed them as vicious beasts with no sense of law and order, that was actually a misconception. It is true that Centaurs prefer wild areas with vast amount of land, but they only attack when provoked, and are actually a very shy species of people.

They are very much a nomadic culture, and tend to travel in small herds through mountain ranges.
