Zytoni

The Zytoni were a semi-sentient species that were discovered on, but not native to, Zyton.

Apperance
The Zytoni had yellow skin, spikes in their back, black finger and toenails and were hunched over. Their heads were shaped like grapes and lacked any visible eyes, although they could somehow see. Jutting from their mouths were four tusks and their mouths were filled with smaller teeth fitted for the det of a carnivore. They were very vicious and aggresive.

History
The Zytoni were discovered on the planet Zyton by colonists from the neighbouring world of Zaros in 4689 BBY. Evidence found there indicated that the Zytoni weren't indigenous to the planet. Twelve years later the wreck of a large spaceship was discovered. Scientists concluded that the Zytoni were explorers from another system (or possibly another galaxy) and had crashed landed there many years before, eventually devolving into simple-minded, animal like creatures. Slavers often attempted to ship them offworld to be sold as guard beasts and as warriors in arenas. They could be taught to use various weapons. A law on Zaros was passed that would protect the Zytoni against slavery.
