En'rg-ch

Colonization: 30,000 BBY - 25,000 BBY (Old Republic Era)
On a planet also in orbit around the sun, Namelesennia, Lord Namelesennius built up a temple where he trained using the Force. However, En'rg-ch wasn't found until 26,000 years BBY. Then, a young Ithorian Sith landed on the planet.

This Sith, his name remain unknown, did like Namelesennius did on Namelesennia; he built a small temple and meditated and trained. A few years later, a group of Twi'leks landed on the planet. With his sword of Cortosis, the Sith slayed all but one of them. The survivor was a young boy, about 15 years old. The Sith took this boy as his new apprentice.

Not much later, Humen came and colonized the planet. By this time, the nameless Sith was dead, betrayed by his apprentice. The fate of this Twi'lek Sith apprentice is yet unknown.

Battle of En'rg-ch: 25,000 BBY (Old Republic Era)
However, the Twi'lek Sith, who was named Kaxs, didn't want to give the Republic control of the planet. He gathered an army and challenged the Republic to war. He controlled his army only through using a Jedi Mind Trick on them. The energy that cost him made himself very vulnerable; a Jedi who arrived to stop the battle found him and killed him.

This, however, didn't help much. Misunderstanding and doubt that grew strong after the Mind Trick turned the planet into an area of bloody civil war. During this war, the enviroment was totally destroyed, and the once so beautyful jungles of the planets turned into poisonous swamps. No Human, Twi'lek or other specie could live on the planet again for thousends of years.

Rise of the Kaxs Family: 33 BBY (Rise of the Empire Era)
Somehow, however, the blood of the Twi'lek Sith Kaxs wasn't dead. In secret, he had married a beautiful Human female. Their child got another child with a Human and so on. On the moon of En'rg-ch 13 (the third moon of En'rg-ch) a young boy was born. Like all men in his family, he was given the name Kaxs, after the Sith that once had been the first person on En'rg-ch. Unlike all previous generations since Lord Kaxs himself, this young boy actually wore some signs of actually being part Twi'lek; he had a reddish skin, thought not as red as the Lethan Twi'leks. His ears also looked a little like those of a Twi'lek, thought they still looked most like those of a Human.

Now, this young Kaxs grew up with his father, also he named Kaxs, since his mother died in childbirth. Kaxs was raised to become a Bounty Hunter, like his father. However, he lost that thought when he was eight years old; his father was killed by a Jedi Master named Yoda.
