The Yash-El are a cycloptic humanoid species native to the planet Yash Prime.
They once possessed a primitive tribal society, in which violence was the best way to absorb or destroy competing tribes. Their species also possess impressive regenerative properties.
This was mostly due to the arid conditions on their homeworld, with little resources. When ancient Synril ruins were discovered on their homeworld, the Yash-El used this knowledge to explore neighboring system for resources. This led to contact with the Terran Federation, who offered homes for several tribes, which a younger generation accepted.
