Goblins

Goblins are the perennial rivals of Gnomes, anarchists and chaos lovers extraordinaire. Where your average Gnome has great intellect and ability to learn, Goblins have an amazing natural aptitude for tinkering with anything they can get their hands on. Look at a new technology: is it efficient, safe, clean and well-designed? Gnomish, or rarely Human.

Does it go boom?
