Suliban

The Suliban are a humanoid species native to Sector 3641, who live as a nomadic race following the destruction of their homeworld in the 1850s.

As a humanoid species they are on a developmental stage that is quite similar to Humans. Their only distinguishing feature were their three bronchial tubes, and their encounters with Vulcans and Denobulans were always very cordial.

Despite living as nomads, by the early 22nd century, many Suliban had settled and were living normal lives in the Tandar Sector. However, that all changed in 2144, when the Tandar patrol ships began to raid Suliban convoys, resulting in reprisals against the Tandarans. In response to the attacks, the Tandarans rounded up all the Suliban and imprisoned them.
