From publisher blurb:
Beneath the streets of human towns and cities, beneath even the holds of the dwarf lords, legends tell of twisting tunnels and dank chambers, of vast caverns and inhuman cities, where a wicked race of rat-like humanoids dwell. Vile and vicious, the ratlings are said to have an extensive civilization in the deep places of the earth. And there their leaders plot the conquest of the surface world.
Welcome to Universal Adventures Tunnels of the Ratlings!
