Trolls and Dwarves
Trolls are the tricksters of the fairy family. They don’t like humans, so very few people have had interactions with them. Unlike gnomes, they are carnivores and tend to prefer goats and sheep. They are said to have superhuman strength and the power of shapeshifting. They also have the gift of prophecy. Trolls live in mountains, by lakes and, of course, under bridges. Their job seems to be testing the patience of the other fairies.
Like the seven dwarves in the Snowhite tale, dwarves are miners. They live deep inside mountains, mining for gold and precious gems. Dwarves are wonderful metal workers, but tend to be tricksters like the trolls.
