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 the Dragon inside it, 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.
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 itself, 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 discarded 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 also be on notably good terms as well.
Prior to its revival, Domino was a dead planet populated by ice crabs 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.
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.
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, as stated by the series' legend, was chosen by the Great Dragon to be its final resting place, and thanks to this, the realm enjoyed a long period of prosperity, happiness and peace. Bloom's birth parents, King Oritel and Queen Marion, were the sovereigns of the realm. It was seen as a beautiful place with enchanting verdant hills and a splendid castle in the center of a valley.
Sixteen years prior to season one, the three Ancestral Witches attacked in their search for the Dragon's Flame under the orders of their master, Lord Darkar, who needed that power to obtain the Ultimate Power. However, before the witches could steal the power, Bloom's older sister Daphne took baby Bloom and sent her to Earth where she could be safe, as Bloom was the next guardian of the Dragon Flame.
In the final battle between the Witches and the Company of Light, the Ancestresses were banned into the Realm of Obsidian by the Company of Light, but grabbed the King and the Queen, who were also imprisoned there. A flow of negative energy was then released which also absorbed all of the population of Domino into Obsidian and the realm was spelled into a seemingly endless winter due to which the whole planet froze over completely and the land was covered in ice and snow.
The palace became encased in ice, and any other architecture could not be seen except Oritel's library on top of the Roc. It was all possibly destroyed or absorbed into Obsidian during the battle leading up to Domino's destruction. Daphne is assumed to be "dead" as she has no physical body. Bloom was then found by her adoptive father and fireman Mike who adopted her with his wife, Vanessa.
Bloom later discovered that Domino was the planet she was born on and raised for a few years until the Three Ancient Witches froze the entire planet while searching for the Dragon Flame. It was then presumed a dead planet inhabited by nasty creatures such as ice crabs and giant yetis.
The planet was revived by Bloom and her friends (minus Nabu) in the movie Winx Club: The Secret of the Lost Kingdom. Life returned to Domino after Bloom with the aid of her "dead" sister Daphne defeated the evil spirits of the witches and then destroyed the Obsidian Dimension and Mandragora. As a result, Bloom also reunited her family and finally met her biological parents.
The second movie took place in Domino.
Domino had two appearances in the first season. The first being when the Simulator sent her to Domino for her test and the second being when Bloom and the rest of the Winx Club went to Domino to find out more about Bloom's past and to possibly restore her stolen Dragon's Flame.
Although Domino did not have a formal appearance, it was seen through flashbacks and talked about numerous times. It was also indirectly mentioned in the last episode by Bloom when she promised to her birth parents to find them.
After Obsidian was destroyed, Domino is restored back to its normal form. A party is then held to celebrate Domino's restoration.
