Ventron

''Our species always rules! - Ventronian Battleship Captain''

The Ventron are a warlike race that were enemies of the Thelean Dominion. The Craton are their sister offshoot race. Their nation is known as the Ventronian Empire.

Biology
Humanoid creatures with a brutish appearance. Standing twice as tall of a man, they are muscular and quite imposing. They have a green, scaly hide along with green fur, sharps claws on their hands and feet, and two pairs of arms - one large and powerful, used in their early stages as their primary means of hunting prey, and a set of smaller arms which are less powerful, but fast and precise. The second pair of arms was originally used to dismember their prey and cut out the good parts, but in their transition to a technologically advanced species, the second pair of arms was used more for precision tasks like building and operating fine tools. While they were fearsome predators in their own right, their homeworld - Ventronia - was home to many creatures far deadlier than the Ventrons.

They are covered in a greenish fur which helped them camouflage themselves in the deep jungles of their homeworld, and parts of their bodies are covered in a similarly coloured layer of scales which offered them some protection from deadlier predators.

the Ventrons are the most physically powerful of the canon THEA races: they have massive highly muscular bodies, and could often rival lesser Hyvon.

Ventronia is a rather turbulent world, home to massive polar ice caps, high volcanic activity, and a relatively small band of temperate regions across the equator. The weather on Ventronia is incredibly harsh, and while the Ventrons were adapted to the overall colder climate, they generally inhabited the more temperate regions.

History
The Ventron come from a planet named Ventras. Ventras possessed small amounts of the extrauniversal mineral known as Hyverium, which eventually attracted the attention of the Thelean Dominion, who invaded and conquered several civilizations in search for anything related to the Ce'Tennan. Although the Ventron were able to fend off the Thelean forces, it came at the heavy cost of all of their colonies, and much of the Hyverium in their homeworld, without it, Ventras became extremely unstable. The Ventron led a brutal war of aggression against the Dominion, which ended up with Thelea taking a direct shot from the ancient Ce'Tennan weapon Regulus, severely damaging the planet. The Thelean have nearly wiped out the Ventrons in retaliation for their actions.

After the Ventronians were defeated by the Theleans and driven off their homeworld, the Ventronians had to roam the galaxy as a nomadic fleet much like the Avikan did. Their ships were far more advanced, and highly capable of defending themselves from Thelean fleets, so they didn't have to worry about being chased at every moment and largely resided on their nearly impenetrable mothership.

An asteroid filled with Stalkers collided with that mothership at some point, and caused the final demise of the Ventronians. Their mothership, while heavily armed and inhabited by tens, maybe hundreds of thousands, was unable to stop the Stalkers from advancing and wiping out pretty much the entire ship.

The Ventronians are largely extinct. There's still a few survivors here and there, but their empire is gone, and they likely won't ever again have the numbers needed to return to the galactic scene in force.

Trivia

 * Ventrons, like Cratons, will be receiving an overhaul by their creator, Aegonian. When it will happen is an unknown matter.
 * Overhaul will remove their ancestry with the Cratons.
 * For their knowledge of Centensian tech - The Ventrons would place between the Akkimari and the Avikan - they had no direct interactions with the Centens, and Centensian research wasn't their specialty, but they were around for a pretty long time and had enough time to come to a pretty solid understanding of (some aspects of) Centensian tech.
 * The Ventron are the only known race to fight an evenly-matched war against the Thelean Dominion and almost win. That would have likely resulted in extinction of Thelean race.
