Eldren appear as tall High Ael with white hair, brilliant jade eyes and alabaster skin.
Their society was patriarchal with females being treated as little more than breeding stock and trophies.
Eldren are known as The Creators and were master Bio-Artificers.
When an Eldrens passion is raised or they use magic their eyes begin to glow.
Their cruelty was legendary.
The Eldren were the first sentient race to settle on Yore and for nearly a Millenia they treated it as their laboratory and playground.
The Edlren altered beasts to become their servants they created the Beastmen to fight their wars and even tried to use them domestically but they were too primitive.
Primitive humans were found to be more pliable and not as violent and were uplifted and domesticated to serve as slaves to the Eldren. They were seen as disposable.
Due to the Eldren being virtually immortal they rarely produce offspring and the rivalry between them caused their numbers to diminish and they became more and more dependent on humans to run and maintain their society.
Eventually, the humans rose against their masters and in an event known as The Purge hunted down their masters, The Purge lasted for 500 years.
