The Neeras

Neeras are a species of tinies often referred to as mouse people. They usually measure between 2 and 3 inches tall, with some slightly larger existing species. They are distinguishable primarily by their mouse-like features such as large, rounded, furry ears, a hairless mouse tail,
and sometimes paws in place of hands, though still possessing thumbs.
They're an intelligent race, just as much as nekos and humans, but they remain very secretive. When venturing outside, Neeras can be bold, opportunistic and audacious but they will almost never reveal the location of their community to anybody.
most Neeras avoid human cities. There is still a pretty sizable colony established in Ayonoore, but you will find most of them in the deep wilderness, in small hidden villages scattered throughout the jungles of the nexus that are nearly impossibly to find.
Most of them are situated in fantasy forests, as the twisted trees and complex root system create endless nook and crannies that are just perfect to hide in. Some neeras have become very good at taming muris, the large green rats carrying and protecting them.
