Whereas gnomes maintain their connection to the fey and natural world, the Mekkfellow have become firmly rooted in the material world and technology. They lack the connection to animals and natural magic, and are much weaker than their northern cousins, but they make up for it with an innate understanding of machinery and quick minds.
