Ratlings

Little is known about this race of intelligent bipedal rat creatures that have taken residence in the city.

Their presence has been found in the shadows in the city: in ruined buildings, basements, and sewers. They seem intelligent enough, sharing language with each other, and some have been even known to be able to speak common.

While posing little harm in even numbers, their ability to breed quickly makes them a dangerous threat. And as the saying goes, if you see one rat, there's probably an army of them in the walls.
