Earth

Earth is a planet of the Magic Dimension. It's the adopted home world of Bloom, the homeworld of Roxy, the Earth Fairies, Selina and Humans, also known as non-magic people.

Overview
Earth is the third planet of the Solar System found in the Milky Way. It is inhabited mainly by humans who live in cities, towns and villages like the inhabitants of the Magic Dimension and the only difference is that magic is not a daily part of their lives. Unlike the realms of the Magic Dimension, Earth is not made up of a single realm and the humans are divided into many countries and the Earth Fairies have many kingdoms of their own, though all the lesser fairy queens acknowledge the Queen of Tir Na Nog as their highest ruler.

Earth has been protected by the Earth Fairies for thousands of years. However, this protection disappeared when the Wizards of the Black Circle started the Great Fairy Hunt and captured most of the Earth Fairies and imprisoned them in their own kingdom, except for one last fairy. Because of this violence, hate, intolerance spread on Earth and the humans stopped caring about nature. Later, the Winx released the Earth Fairies and defeated the evil Wizards, restoring the Earth Fairies' protection on Earth, and it became linked to the Magic Dimension once again.

Humans
Also called "Non-magic people", they are the majority of Earth's population. They also created technological devices that they use in their daily life mostly as a replacement for magic. However, they're less efficient in comparison of those found in other planets within the Magic Dimension, and many humans are unaware of its existence, despite magic being restored on their homeworld.

Books
In Fairy Insider, it tells about Earth's Elements Dragons, Earth, Air, Fire and Water, with what they stand for, and tells about Earth's good luck charms: horseshoe that nailed over the door to keep bad luck from entering, wishbone from thanksgiving works as wish determiner, and others to carry or wear: rabbit left foot, four-leaf clover, tiny elephant, charm bracelet, good-luck coins (usually of brass, with good-luck sayings).
