Zhell–Taung War

A war took place on Notron, the homeworld of both the Taung and the Zhell species.

Prelude
Thousands of years before the rise of the Galactic Republic, the planet Notron was inhabited by two species: the Taungs and the Zhell, the ancestors of the modern Humans. The Zhell organized themselves into the thirteen Battalions of Zhell, also known as the Nations of Zhell, and eventually came into conflict with their Taung neighbors.

The war
At some point amidst the conflict, a volcanic eruption brought devastation upon the Batallions of Zhell, when it smothered their capital city with thick ash and nearly destroyed their race. The enormous plume of released ash and smoke was so dense and wide-spread across the sky, that it blocked out the light from the sun, leaving the land beneath in darkness for two years. The Taung immediately took the advantage that nature had provided, and in the aftermath of the eruption, subjugated their age-old enemy.The Taung viewed the smoke and shadow as an emblem of their destiny, and it was then that they adopted the name Dha Werda Verda for themselves, a title that meant "Warriors of the Shadow" in the Taung language. However, the Taungs' victory over the Zhell was doomed to be a fleeting one. Over time, the Zhell eventually managed to win back control of Notron and drive the Taung from their shared homeworld.
