Buban

The Buban owned freighters on which the Orion slaves Ombrey and Maark served as senior officers. The Orions stole two freighters, named the Revenge and the Fate, in a well-planned heist, leading to the birth of Orion piracy in a legend known as the Orion Dawn. 


 * By the context, it's implied that the Buban are an alien race and signatory to Treaty of Kammzdast. However, neither of these points are definite.
