I was thinking of something like this? I always thought about bringing them into a D&D environment, but never got around to it.

[b]Name:[/b] Mesocricetian (Meza-cry-seat-ian)

[b]Race Bio:[/b] Humanoid rodents, akin to [url=http://en.wikipedia.org/wiki/Skaven_%28Warhammer%29]Skaven[/url], but taller and bulkier. On average, whether female or male, they stand between 5 and 6 feet. They have large bearish heads, with big black eyes and leaf-shaped ears sprouting from both top corners of the skull. Their fur can vary in colour extensively from each individual, and there are several Mesocricetian subspecies dotted around the globe, each with their own physical characteristics. 

They travel on padded feet with five toes, each mounted with a stubby claw. It is for this reason, that they seldom wear anything on their feet, unless a situation demands it. Their paws consist of four fingers, likewise attired with small but sharp claws, though this does not hinder their ability to grip things. In fact, they are renowned climbers, who often choose to settle in high places if they are unable to burrow into the ground.

Perhaps one of the most noteworthy features of the Mesocricetians is their ability to store food in large cheek pouches, which can then be preserved for some weeks. Legends read that long ago, armies of the species were able to march great distances without stopping for food, and that this advantage allowed them to outmanoeuvre their enemies on several occasions. 

The Mesocricetians are an agile race, and strong too – however they are generally considered unfriendly, even towards each other. Many a Mesocricetian Kingdom has been torn down on the same day it was established; such is the mistrust and aggression they hold for each other. It is for this reason that they mostly keep to themselves, living far out in the wild and meeting up only to trade or procreate. 

Perhaps the greatest weakness of these rodents on an individual level is their fear of magic; many believe it is an evil presence, unnatural and not suited for the hands of mortals. They will generally steer clear of magic users, or when they must fight them, they will opt to remove the threat before it has time to cast a spell.
