Domino

Domino is a realm that possibly holds the greatest amount of influence and importance within the Magic Dimension thanks to it being the resting place of the legendary Great Dragon.

Overview
Domino is a vibrant realm that was created by the Great Dragon and chosen to be its resting place once it had completed creating the rest of the the Magic Dimension. Since then, the Dragon has entrusted a spark of its miraculous flame to the realm's royal family, where it had been passed down through generations from heir to heir. It is also thanks to the Flame that Domino's monarchy has seemingly maintained high importance when compared to those of other realms. Issue 149 of the Winx Club Comic Series, also shows that the realm is also either the home or starting point of the Guardian Nymphs and even holds a chamber dedicated to each nymph that has graced its history; further adding onto just how important the realm is concerning the Magic Dimension's safety and magical balance.

As of Season 6, it is revealed that a chamber had been built around the Great Dragon to better contain it. The chamber was also used as training grounds to test Keepers of the Dragon Flame, until inside it the Dragon having turned into one with up to five heads, became too volatile to safely train with.

Additionally, Domino is also shown to contain up to three moons or satellite asteroids that serve no significant purposes.

Society
Like a majority of the realms within the Magic Dimension, Domino is run by monarchy with King Oritel and Queen Marion as its current rulers. Daphne, who had been formally coronated by Season 6, is set to succeed her parents as Bloom, the youngest princess, will go on to rule Eraklyon should she finally marry Crown Prince Sky. Additionally, since the realm's beginnings, members of the royal family have been entrusted with the Dragon's Flame: a spark of the original fire the Great Dragon itself used to create the Magic Dimension. Traditionally, it is the first-born who receives the Flame and becomes its newest Keeper; the only exception to this being Bloom as Daphne had transferred the Flame to her in a time of crisis. Also, it is revealed in "Vortex of Flames" that a chamber located beneath the royal palace which houses incredible flames, as well as the Great Dragon's test, was once used as training grounds for Keepers of the Dragon Flame. Though, at one point, the Vortex's flames began to burn beyond anyone's control and the test surrounding it was discontinued to secure the Keeper's safety. In spite of this, Bloom, the current Keeper, was able to pass the test, even as her body had been weakened prior to being thrown into the Vortex.

The people of Domino seem to be moderately traditionalistic, as evident by Oritel's behavior throughout Magical Adventure in trying to rush Bloom into adapting to the life of a royal. Additionally, Domino seems to be home to many brave heroes and natural-born leaders, with the members of the current royal family being ones themselves: Oritel and Marion formed and led a group of skilled warriors to protect their kingdom (and possibly many others) from ancient evils in the Company of Light, Daphne went on to become one of the Nine Nymphs of Magix, also becoming the Supreme Nymph among them, and Bloom currently leads the Winx Club, a group of six fairies who have gone on to protect the Magic Dimension, succeed the Company of Light, and become some of the most powerful beings within the Magic Dimension's history. One issue of the comic series titled The Guardian Nymphs also implies that Guardian Nymphs similar to the Nine Nymphs of Magix may have originated on Domino and continue as a long-standing tradition in which those who become nymphs go on to protect the Magic Dimension as they are immortalized within a special hall in the royal palace. Older nymphs whose flames begin to die out select and train protégés to take their place once they become worthy enough.

Lastly, given how many ties Domino's royal family maintains with Eraklyon's—Oritel's friendship with Erendor, Daphne's marriage to Thoren, and Bloom's engagement to Sky—the people of both realms may be on notably good terms as well.

It served as the meeting place of the Council of Sovereigns during the war against Tritannus highlighting Domino's influence in the Magic Dimension.

Fauna
Prior to its revival, Domino was a dead planet populated by goldums and yetis. A giant stone bird called a Roc also protected Oritel's hidden library. After the revival, life returned. Some frozen animals survived the magical ice age. The fauna is presumably similar to Earth's.

Like all other planets, Domino has its own Ocean Gate which is located in the Yellow Reef and is guarded by the planet's own Selkie, Serena who also uses the dragon's flame.

According to Serena, all of the rarest species of fishes in the whole Magical Dimension live on Domino, probably because the planet was buried in ice for so long.

Flora
It is assumed to be similar to Earth's but more lush. Much of the plants are green and many flowers can be seen throughout the realm.

 * Domino's history as a prosperous realm which was destroyed by evil magic and had to be revived by the protagonist of Winx Club, Bloom, who destroyed the source of that evil magic, is similar to and might be based on the motif of the Wasteland from Celtic mythology, according to which a country becomes barren due to a curse which must be lifted by a hero.
