Mulako Corporation
this corporation was set up on a huge comet that wandered through an uncharted system every hundred years or so. They stripped the outer layers of primordial ice off the comet as it passed through its orbit, and distilled it for sale as a gourmet water to self-important chefs and dignitaries. When the comet neared the star it orbited, it was also used as a resort. The corporation had dug out luxurious living spaces deep within the comet's core, and opened them to the well-paying public twice each orbit. The first time came as the comet neared the star; the second came after the comet had passed close to the star and was on its way out of the system. During these two, three-month periods, the evaporating elements in the comet created a breathable environment for non-workers. When the comet was close to the star, the environment was too hot and the gases too plentiful. When it passed beyond the star, the comet was too cold. During these times, the comet is only inhabited by the workers of the Mulako Corporation.
