Elae, Saorae and Arai (Elves)
Minotaur
Kalfalter
Zmei
A group of closely related species that hail from Eobayn. As a collective, they're often called elves due to linguistic shenagians. Across the universe this is often considered an inoffense word, but on Eobayn the term is effectively a slur. It's an umbrella term, and the people of Eobayn would rather not be grouped together despite being closely related and technically sharing an empire.
Outside of Eobayn itself, most people are only familiar with the elae. With blue-toned skin and ridiculously-long ears, they control a large portion of the universe through military might. Elae strongly prioritise combat prowess, magical talent and one's own beauty and elegance, and tend to expect that other societies act in the same way. Failure to do so is their own failing.
It could be easy to assume that saorae are a more peaceful species, and perhaps that was once the case. Around 1000 years ago, they were victims of genocide at the hands of armies led by an elae warlord. A saorae warrior made a bargain with their pantheon's rarely-worshipped god of misfortune, killed the warlord, and terraformed Eobayn's moon for saorae habitation. Since then, the surviving saorae society have adopted a far less peaceful way of life, enough that their skills are now highly regarded by their former enemy.
The golden-skinned arai rarely associate with outsiders, especially those from other planets. They specialise in magic that warps flesh and bone; a technique considered to be too disgusting for any self-respecting elae to bother learning. Not that an arai would ever teach them.
The four-legged cowfolk hailing from Tarou. Minotaurs are one of the few species that achieved space travel without the use of the Highways. They were also the creators of what is now considered the written language shared by much of the known universe. This was created for economic reasons. It's much easier to trade with people you can understand, after all.
Long ago, the minotaurs decimated their planet due to their own pollution and greed. The planet was saved thanks to the intervention of alien species, who had an interest in seeing whether their terraforming techniques would work. It did, and while the minotaurs have continued their capitalist pursuits, they now do so while considering ecological impact for their planet and the others that they have colonised.
The term "taur" originally refers to sentient creatures on a whole, also being used by the extinct centaurs that were in conflict with the minotaurs, but the term itself has fallen in disuse, alongside the original minotaur language.
Kalfalter are ocean-dwelling amphibians with traits similar to seahorses. Their body shape varies widely depending on racial background. For example, the Stonefolk resemble coral, and the Foresters sport a an appearance similar to seaweed. Alongside this wide variation between the same species, Kalfalter also vary greatly between sexes, though they also sport the ability to shift their sex perfectly.
Despite their small size, they're known for their significant strength and are often hired as mercenaries.
The zmei are humanoids covered with scales and adorned with feathered ears and tails. Many zmei worship the Original Dragon, from which the Highways were created, or they worship the still-living dragons that wander the void. While they don't tend to colonise planets in their name, they are widely known as explorers, often making pilgrimage to the site of the corpse, or simply as pirates.
