Groulien Salt-Hogs, or just "Salt-Hogs" for short, are the manual laborers of the galaxy. They are hard workers and fairly easy to please. They work essential station facilities, such as the Recycler and the Factory. They are one of the armed species, and the sheer size of their population makes them the necessary backbone of station operations and security. This also makes them - unfortunately so - entirely expendable. Luckily, their pleasant demeanor keeps you from feeling guilty for taking such advantage of them.
They are a short and stout people, dressed in beige-colored body suits that also function as their work uniforms. Salt-Hog tastes are simple and cheap, and will tend to make use of the cheaper station facilities, but this will not stop them for springing for an enjoyable stop at a Love Nest. They get along with most people, except those who are a bit too snooty given their economic and/or social status. Their society is a commune, with all Salt-Hogs considered equal in the fact that they are all underpaid, overworked, and unappreciated manual laborers. It is their lot in life, and they harbor no resentment for it.
In essence, they are the galaxy's Irish.
