Vol V Chapter 30

A gnome was a very evil and dangerous creature. It fell under the kind of magic beast that was almost entry-level, and its individual power was not strong. But when it came to its ability to appear threatening and destructive, it easily beat a variety of magic beasts and ranked among the top few. 

The crux of the problem lay in their powerful reproductive capacity, as well as their astonishing adaptability. There seemed to be no place in this world where the gnomes could not thrive and multiply. Even in Ashes Woods that were brimming with negative energy, there would be traces of them to be found so long as those places were slightly closer to the edge of the forests.
