For those truly amazing submissions.
Sometimes Utopias should stay as mere legends.
Old cultures since the dawn of written time have seen pictures in the night sky and asked questions of them. Who they were, where did they come from, and why do they return? The earliest efforts to distinguish these nightly visitors and give them names and meanings dates back to before the Contention of Aborior. Those first observations were different than what is seen today but most still hold true to their original origins.

A group of humans living in a mountainous area have spent generations mining, drinking home made liquor, and generally not spreading the gene pool around enough. The end result is a sub-race of humans who no longer have necks, rather their heads protrude from the upper portion of the torso between the shoulders. They have beards, and lacking the ability to turn their heads, can only see what they are directly facing. They are simple and to the point, and direct to the point of bluntness.
