GNOMES

Are elementals of the earth: caves, crystals, gems, roots, trees and sand.
They can look similar to the garden gnomes you have become accustomed to over the years.
They reflect the element they belong to and are deeply wise. It is believed they live for thousands of years.

Other earth elementals/faeries include: brownies, pixies and goblins who have similar traits to gnomes but these can be mischievous and tricky and are not as dependable as gnomes.
