Vouran

Vourans or commonly known as "Tubers" are a fragmented remnants of an ancient galactic empire.

Biology
This species' biology has been thoroughly contaminated by mutagen that only their "tubes" are their distinguishing feature, hence their nick-name.

There isn't a standard description of a Tuber, as to list the variations would be like printing a catalog of all life's possible variations.

All Tubers possess 'tubes' which function as biological air-exhaust pipes which in zero gravity they can use as a form of propulsion.

Culture
The Vourans control the Free Trade Zone of the galaxy, a home of merchants, manufacturers, and capitalists.
