Sanyassan

The Sanyassan Marauders are a barbaric humanoid species from the planet Sanyassa. They have ape-like faces, scaly green-gray skin, and are on average over two meters tall.

Around 100 BBY, a group of them turned pirate and hijacked a spacecraft. Unable to operate their advanced vessel, they crash-landed on the Forest moon of Endor. There, they built themselves a fortress, ruling over a section of the Endorian plains. The Sanyassans armed themselves with poorly maintained blasters and more conventional weapons.
