The ethereal entities of the four kingdoms, Earth, Air, Fire, and Water, are forces of nature. The Dutch writer and clairvoyant Mellie Uyldert characterized the semblance and behavior of ethereal entities on the etheric plane, which, she said, hover above plants and transfer energy for vitalizing the plant, then nourishing themselves on rays of sunlight. She depicted them as asexual gender, and composed of etheric matter. They fly three meters over the ground, some have wings like butterflies while others only have a small face and an aura waving graciously. Some are huge while others may have the size of one inch.
