The dominant native race on New Luna, Yoescu (also known as ferretmonkeys) are two foot tall semi-intelligent quadrapeds (able to waddle on their back legs) with blunt, weasel-like snouts, opposable thumbs on all four limbs, long, prehensile tails, and a picture-based telepathy. They are a hoarding species, collecting metallic and shiny items in underground and otherwise hidden caches.
