The Yandians are the information nerds of the galaxy, and a mammalian race of anthorpomorphic cats not unlike a tabby or common house cat. The Yandians are both skilled at information gathering, as well as personal close quarters martial arts combat. This is because, while the Yandians despise battle and fighting, as it destroys knowledge, they understand the need to protect the vast wealth of knowledge they have collected. And thus, every Yandian, most especially their librarians, are taught how to defend that knowledge at all costs. The Yandians are also a very benevolent race, sharing much of what they know with the galaxy, either directly, or through the use of libraries known as Dens of Knowledge.
