Murine creatures, sometimes called mice, mouslings, ratkin, and rabbit people are descended from humans and small woodland creatures shifters. They cannot fully change shape as their full lycanthrope forebears could, but can take on a quadrupedal form — a state they call shifting. Murine have evolved into a unique race that breeds true. They have a distinct culture with its own traditions and identity.

Physical Description

Murine are basically humanoid in shape, but their bodies are exceptionally small and covered in fur reminiscent of the breed of murine strongest in their genes and can range from the black of a rat, spotted as a rabitt, grey as a mouse, etc. Males tend to be taller than human average, ranging from 4 to 6 feet, while females are typically smaller, ranging from 3 to 5 feet tall. They often move in a crouched posture, scurrying along while their companions walk normally alongside. Their faces have a bestial cast, with small, pink or red noses, beady eyes, flat teeth are prominent in the rabbitfolk and sharp but small for their rat counterparts and all have ears and a tail reflective of their breeding.

The personality and behavior of shifters are influenced by their animal natures. Murine are bred from creatures that hide themselves in shadows, hunt and keep secrets, and travel underground out of sight. Many are highly regarded from the most esteemed in society all the way down to the gutter filth for their subtle way of locating anything and everything as well as their ability to slip unnoticed into smaller spaces.



Many races feel uncomfortable around murines the same way they feel around any small rodent. Of course, some grow to appreciate individual murine despite their natural aversion, and halflings in general get along well with them. For their part, murine are accustomed to the disgust and don’t expect better treatment from members of the other races, although some try to earn respect and companionship through acts and deeds.




Murine speak Common and rarely learn other languages.


Murine use the same names as humans, often ones that are short in syllables.


Moving from the small, confined spaces of their home to crawl through a dungeon is a small step indeed. Many murine find themselves embarking on adventuring careers after something happens to disrupt their everyday routines—a monstrous incursion into their village or forest, for example, or a guide job gone sour, or simply the love of finding something shiny for their collections.
