What if some crazy wizard created an artifact that empowered rodents that touched it with one random supernatural power? Preferly right out of the pages of your favorite four-color. (But only one power!) This item does not convey any sort of intelligence boost.

The Forest of Throck:
Throck forest is divided into three parts: a region of twisted black magic, which is dark and hemmed in with the legions of sable pine. This is Spindel, and is occupied by the hideous Ettercaps and their spider-pets. The second area is the chaotic elfin-wood, where the druids work their wyrd magic amongst the oaks. The last part is Udnalor, the home of the gnomes. Finding themselves surrounded by these chaotic forces they dwell as quietly as possible beneath the surface. Their culture is a fascinating one to visit, and in the next few miscellaneous ideas, I shall examine the ways and customs of THE GNOMES OF UDNALOR, with a view to role-playing them.
