Nymphs of Magix/Series

Retconned
It is unknown when Omnia assumed the position of one of the Nine Nymphs of Magix but she has since been acting like the liaison between the Magic Dimension and the Infinite Ocean where the Pillars of the Infinite Ocean, the pillars of the foundation of all the realms of the Magic Universe, are found. She might also had met Egerya, a fellow nymph, during that period.

When she came of age, Daphne assumed the role of Supreme Nymph and has since guarded the Great Dragon for years with Tetis and the other nymphs. It seems that Tetis had continued to do so even during the absence of Daphne and Politea.

After acquiring their Sirenix, Daphne and Politea confronted the Ancestral Witches in the Infinite Ocean, where they casted a terrible curse on Daphne's Sirenix, that would turn her into a disembodied spirit should she try to use her new Sirenix powers.

Politea, who refused to help her friend in her most desperate time, was also cursed by the Witches and turned into a ravenous sea-beast once her powers were fully corrupted. With the last two Sirenix fairies defeated, the Witches would go on to curse Sirenix itself to ensure that no other fairy would think of achieving it.

Aware that the Dragon's Flame had been passed down to Oritel and Marion's baby girl, the Ancestral Witches sought Bloom out as they left Valtor to do battle with the Company alone during their raid on Domino. As they raided the castle, they chased Daphne down for Bloom but, just as the Dragon's Flame was within their reach, Daphne sent Bloom to a place where the Witches would never be able to sense her: Earth. Ready to face the Witches, Daphne tried using her newly acquired Sirenix powers to defend herself, but the curse placed over it turned her powers against her and rendered her as nothing more than a spirit without a body, unable to help defend her home.

Season 1
In "Betrayed!," Bloom dreams of a woman calling out to her. Not having much time, the woman introduces herself as Daphne, asking Bloom to come to her. As she dreams, Flora consults with Stella as Bloom is once again talking in her sleeping and phasing in and out of her Winx as she calls out. Later, as Bloom and the Winx walk in the quad, Tecna scans Bloom with her Dream Probe, and in conjunction with what Bloom has told her about her, manifests a projection of the woman, which Bloom verifies. After seeing the projection, Bloom remembers seeing her on the facade of the Temple of Magix.

Later, using the Research Lectern, Bloom begins her research session. She finds that Daphne was not only a fairy but one of the Nymphs of Magix, the supreme fairies who ruled over the Magic Dimension during the eons following the Great Dragon's disappearance. During this time, commotion ensues as the Golden Gate tries to open and present the books inside to Bloom. After Bloom leaves the library, Faragonda reads one of the books scattered on the floor which reads "Daphne the Nymph" and immediately orders Barbatea to shut the library without using magic.

In "Bloom Tested," Bloom daydreams of Daphne calling out to her in a wishing fountain.

In "Miss Magix," Bloom, on a date with Brandon, tells him about the dreams she has been having about the mysterious woman who calls her by name. Along with her voice sounding familiar, Bloom states that she looks familiar as well, albiet Bloom does not know why. She says that it cannot be coincidental and suggests that she may be showing her the way to something. As they walk, Bloom asks why she possesses such powers and why they come to her so easily. The nymph in her dreams wants to tell her something unbeknownst to her.

Bloom informs Brandon that the middle nymph on the facade of the temple in the square is Daphne. Every night, she calls to Bloom asking her to come to her. She tells Brandon about her research session a few days ago and that the books she found had dissapeared when she came back, obviously hidden by someone. There are so many things she wants to learn. Brandon suggests that Timmy will find whatever information she needs in Red Fountain's library.

In "Honor Above All," Griselda takes Bloom into Faragonda's office to discuss why she has been sleeping in class. Bloom confessses she has not gotten much sleep because of the voice she hears in her sleep calling her name. Faragonda comforts her and tells her to rest as they will talk later. Later, as she sleeps, Bloom dreams of herself walking in a temple as the voice calls out to her. Faragonda calls Bloom to her office and tells her that the advisory committee has just held a special meeting concerning Bloom.

Faragonda concludes it is time she found out more about her past. She tells Bloom the voice she hears belongs to Daphne, the Guardian of the Dragon's Flame and legend has it she lives in the depths of Lake Roccaluce. With that, Faragonda astral projects herself and Bloom to the depths of the lake as Bloom sees an apparition of Daphne holding out a chest with a tiara inside and presents it to Bloom. The projection ends and Bloom asks to know more, but Faragonda says she must discover the meaning of what she saw on her own.

In "The Font of Dragon Fire," after having embarrassed herself at the Red Fountain exhibition, Bloom decides to leave Alfea and return to Gardenia. The Trix catch wind of this as she passes the café they are in, and decide to use this opportunity to rip the Dragon's Flame from Bloom. Within the following days Bloom returns home to find Mike and Vanessa at the Trix's mercy. Bloom manages to save them but the Trix easily overpower her.

They then tell her that they are seeking the power inside her: the Dragon's Flame. Their ancestors destroyed Domino to get it, and would have succeeded if not for Bloom's sister, Daphne the Nymph, who put the power inside Bloom and sent her to Earth. Icy tells Bloom that she is the last surviving heir to the throne of Domino, and the guardian of the greatest power of the universe. The Trix then use their Vacuums to steal her power. After Bloom regains consciousness, Stella arrives and Bloom decides to go back to Alfea to reclaim her power.

In "The Fall of Magix," Bloom tells Faragonda that she finally knows what her purpose is, or was before she lost her powers. She reveals that she is the last princess of Domino and Daphne the Nymph is her sister. Bloom is shocked to find out that Faragonda had already suspected something like this. Bloom further says that the Trix stole her power, and that they are very similar to the Three Ancient Witches as a strange light shines in their eyes. Faragonda becomes frightened and says this does not bode well for Magix.

In “"The Crown of Dreams," Daphne takes the Winx to Domino's treasure room in order for Bloom to discover her origins and a great secret. There, Bloom finds her tiara and it tells her the story of her destiny: to be the keeper of the Dragon Flame, the power that keeps the Magic Dimension safe from evil. The Three Ancient Witches, the first creatures of evil, tried to steal the power of the flame, and although they failed, they destroyed Domino in the process. The witches overpowered Daphne, but she saved Bloom just in time. The king and queen of Domino, thinking they had lost both their daughters, went into exile to grieve. Even today, they still pine for their beloved girls. Bloom is saddened to learn the truth, but Daphne encourages her to be strong. Bloom swears to her that as soon as the threat of the witches is over, she will find her birth parents. Now it is off to Magix to reclaim the Dragon Flame.

In "The Witches' Siege," at Alfea, the students and professors from the three schools all battle against the Creatures of Darkness. Meanwhile in the Dark Forest, Bloom hears a voice calling her name. She realizes she must go to Lake Roccaluce. It has something to do with her past, Daphne, her parents, and her powers.

In "The Ultimate Challenge," Bloom arrives at the lake and finds Daphne. Daphne says she has not lost her powers. She shows Bloom apparitions of her life and says she was brought up by caring and understanding people. Bloom belittles herself by saying she let them and her friends at Alfea down, and she does not belong anywhere, but Daphne assures her that she is the same as she always was and her past will always belong to her. She was lost, afraid, and came to believe what she loved was taken from her, but the truth is no one could steal her past, dreams, or powers. Bloom must look deep inside herself to recover her powers. Daphne fades away and Bloom emerges from the lake in her Fairy Form.

Season 3
There were also statues, representations and relics of them at the Museum of Magix which could be seen in the episode where Valtor breaks into it to steal the Agador Box.

Season 5
Bloom goes to Lake Roccaluce to get more information on Sirenix from Daphne and learns that the form had been cursed by the Ancestral Witches, which resulted in Daphne being rendered as "a spirit without a body" when she tried to use it against them.

After enduring so much torture following her capture, Daphne eventually breaks and reveals the secret of Sirenix to Tritannus. He then plots to destroy the Source of Sirenix.

Tritannus strips Daphne of her powers and gives them to the Trix. Daphne's Sirenix powers mixing in with Tritannus' dark magic gives the Trix the power of Dark Sirenix.

After the Winx have restored the Lake of Roccaluce, Guardians of Sirenix open the gate to the Infinite Ocean and Omnia appears in front of it. She is introduced as the Supreme Guardian of Sirenix by the selkies, and announces that the Winx are now Sirenix fairies, before letting them into the Sirenix gate.

After the Winx have transformed into Sirenix and enter the Infinite Ocean, she tells the Winx that as Sirenix fairies, the Infinite Ocean is always open to them. Not long after the Winx explore the Infinite Ocean, she also tells the Winx that as Sirenix fairies they are each granted a wish. The Winx are delighted to hear the news, but Omnia later tells them that there is new evil in the Infinite Ocean, and that they need to fully develop their new powers to rid it.

Tritannus targets the two remaining Pillars, the Pillar of Balance and the Pillar of Control. In an attempt to stop him, Daphne contacts Bloom through her dreams and tries to direct her to the Eye of Inspiration to help the Winx learn where the two pillars are located.

Tritannus and the Trix learn of the existence of Politea, a nymph who was corrupted into a sea monster due to the Sirenix Curse and her lust for power. Believing Tritannus to have failed, Darcy and Stormy leave him and Icy behind to search for Politea themselves.

The Winx learn of the Sirenix Curse and, through the use of Chrono Magic, Bloom witnesses Politea's betrayal and the cave she now resides in. Not wanting to put her friends in danger, Bloom goes to Politea's lair on her own, only to find Darcy and Stormy already absorbing the sea monster's Sirenix powers.

Bloom frees Daphne after defeating Tritannus and uses her Sirenix wish to break the Sirenix Curse forever and Daphne becomes a corporeal person again.

Season 6
Daphne is seen to be getting used to her body after being a spirit for many years, and is therefore having difficulty moving around without tripping and stumbling. Bloom and the Winx promise that she will get her accustomed to her new life in no time. She receives a cellphone from Tecna with all the latest apps and Aisha teaches her how to dance.

The Winx fend off the Beast of the Depths and help Daphne regain the confidence needed to transform into her own Sirenix, which she uses to subdue the monster.

Daphne becomes the crown princess. During the celebration, Bloom starts to feel weak from sharing her Dragon's Flame with the Winx, and Selina releases the Fire Eaters to attack her. Sky carried Bloom to safety but Diaspro lures him and Thoren to bring her to the Vortex of Flames to throw her in there, telling them that it could restore her powers while it would in fact kill Bloom. While the Winx fight back, Daphne went with the boys to stop them but Diaspro throws her in the vortex which angers Daphne and she fights Diaspro back, but she shields herself and then disappears. Luckily, Bloom rises up from the vortex after battling the five-headed dragon with her own Bloomix powers. They both get back to the ball room and help the Winx to finish the monsters.

The Mystery of the Abyss
Set immediately after Tritannus' defeat and banishment to Oblivion, the Trix, who have evaded capture, journey back into the Infinite Ocean, where they try to seize the Emperor's Throne for themselves but end up meeting with Politea, the nymph who betrayed Daphne when she needed her the most. She explains that when Darcy and Stormy had absorbed her power, they dispelled the evil in her Sirenix, allowing her to slowly come back. Once they are later joined by Tritannus, the five villains seek out a pearl hidden within the deepest depths of the Infinite Ocean capable of bestowing its wielder with immense power.

The Winx try to enter the Infinite Ocean to rescue him but learn from Omnia that Tritannus had sealed all entrances into the dimension. The only one that remains untouched is the one linking the Infinite Ocean to Oblivion.

Tritannus successfully pressures Omnia into revealing the whereabouts of the Pearl of the Deep—the Coral Barrier—and hurry to it.

The Winx manage to free themselves from Oblivion and cross over to the Infinite Ocean. They are then met by Politea at the Emperor's Throne and try to fight her only to lose terribly. The Winx go to Omnia's Cave as Politea remains bound to the Throne. They then pursue Tritannus and the Trix upon learning where they went.

Tritannus and the Trix return to the Throne with the Pearl of the Deep, only to realize that they had been fooled once Politea steals the Pearl away. As the Trix try to fight Politea for the Pearl, Sky escapes his imprisonment but cannot flee. Politea completely overpowers the Trix and hypnotizes them along with Tritannus and his mutants. The Winx make it to the Throne but are immediately attacked by those under Politea's hypnosis. Omnia and the Selkies join the battle where Politea and Omnia unhappily cross each other again. Serena snatches the Pearl and gives it to Bloom who uses it in a Convergence with the Winx to defeat Politea and clear the oceans of any pollution that may have been spread. Omnia also heals Sky using the Pearl.
