Fairies are magical creatures that live throughout the Magic Dimension. Their source of power are the light aspects of magic such as positive feelings. However, some fairies use their powers for evil. Fairies can create emotional or empathic bond with pixies, Selkies, and Fairy Animals. Fairies have the option to switch to a witch and vice versa, although this is a rare case. While most known fairies are female, male fairies do exist.
There is also a notable rivalry between fairies and witches. Their opposed natures often cause tension between the two groups, including exclusion from certain events or physical confrontation when provoked. It has been stated that witches do not like fairies because they think fairies live easy lives. Despite this, fairies and witches have been seen working together in times of hardship or realm-wide emergencies, and can cooperate after some time together. There are also significant and long-lasting friendships made between fairies and witches, even with some friendly rivalry.
Most fairies use their powers for good, protect the Magic Dimension from the forces of evil, and work to help others. Some fairies use their powers for evil or ally with dark forces for selfish means, and others, while not necessarily evil, stray to the dark side and do bad things, such as seek vengeance or have a lust for power.
All fairies are mostly human in appearance with some being composed of pure energy or resembling animals or elves.
Long ago, seven Ancestral Fairies crossed over from the Legendarium World and spread their magic throughout all the worlds the Magic Dimension, including the Earth. In ancient times, Earth was protected by Earth Fairies, but then the Wizards of the Black Circle found a way to resist the fairies' magic and absorb it and began the Great Fairy Hunt which lasted for centuries. The absence of fairy magic allowed pestilence, war, and hatred to instill upon the Earth. Other ancient, all-powerful fairies such as the Arcadia, the first fairy, and the Ethereal Fairies, live outside of space and time. The nine Nymphs of Magix ruled the fate of the Magic Dimension and were the Keepers of the Dragon's Flame after the disappearance of the Great Dragon.

Fairies must attend school to become full-fledged fairies and master their powers. To do so, most fairies attend Alfea. There, the fairies are taught and trained to develop and increase their powers and to use their powers responsibly so as to help preserve the Magic Dimension and fight against evil using light magic. Other schools include Linphea College, Eraklyon Institute, the Golden Auditorium, and Tir Nan Og College.

Fairy Forms or Transformations are different levels of power that fairies can attain as an extention of their magical abilities. Fairies’ abilities are limited in their civilian forms. To increase their magical abilities, they transform into fairies and are able to use their powers with greater ease, gain wings, and new clothes and accessories. There are standard fairy levels, which are gained during a fairy's formal educational journey to become a full-fledged fairy, and an infinite number of higher fairy levels and acquired powers meant for specific situations.
