Sisimii

A race of sentient, omnivorous goat-like creatures. They didn’t have opposable thumbs, but their hooves were more mobile than a goat's, giving them some degree of grip. Their shoulders were higher than their hips, like a giraffe. Sisimkh were largely quadrupedal, but could stand on their hind legs if needed, like a bear. Males had either two or four horns, depending on ethnicity. While not incredibly technologically advanced, they were the first of Iuldar’s geologically-modern races to build fortified towns and work the metal krithite (a hard, black allotrope of palladium). The Sisimkh, and ghiirka in general, have a genetic grafting ability. A handful of Iuldar’s species developed this as a survival mechanism, and it allows them to mate with other animals (provided the genetic separation is not too vast). It was through this ability that the Sisimkh left a legacy on Iuldar, in the form of their half-Jhiriska descendant race, the T’shodans. The original Sisimkh themselves, however, are extinct.
