This species of alien beings gets used quite a bit in all of my settings, including formal mentions in Glow and Spacers. Special thanks to Trevor Hudgins who first let me play one in his own post-apocalypse setting. I've been a fan ever since.
The Akebbarik, also called "Space Goats." Despite a lack of hair, these humanoids' heads resemble that of goats. Most encountered cultures are interested in trade and commercial transactions. Amongst themselves they call all human-like species, including humans, "Xylon-kin."
They appear in all of the Mu Verse's continuum calling themselves "The Trading Empire." For the most part they are friendly to the Earth and its inhabitants. They are very profit-driven though and may be working with anybody, including those that could be planning some pretty nefarious things.
