Long ago, in a tavern far, far away….
Just outside of the Betelgeuse system, there was a bar. There were actually several bars. In fact, the moon-base that this particular bar was on was part of a vast lunar pub crawl orbiting a trendy brewery planet. It is a widely known, and popular fact that a better portion of the galactic trade economy revolves around alcohol; This is partially because of a generally loose and happy go lucky attitude on the part of the people of many species across the galaxy, but also because nobody is really having a good time at it and seek to drown their proverbial sorrows. The generally loose and happy go lucky attitudes are a direct result of everyone being pretty much drunk out of their minds pretty much most of the time.
