They are back

After defeating the Black Circle mages in Andros and saving the Earth fairies, long-awaited peace finally reigned in the Magic Dimension. The Trix were finally defeated and erased from the magical map of the world—their dark energy dissipated without a trace. Domino blossomed: the Dragon Fire Kingdom regained its glory, and Bloom spent more and more time in the palace with her parents, King Oritel and Queen Marion. The Earth slowly adjusted to magic, and the Winx opened a new chain of pet shops in Gardenia and basked in their status as the greatest fairies.

But this world was an illusion.

In the deep, forgotten catacombs beneath the ruined Castle Darkar, where the line between reality and Oblivion thinned, those destined for death met. Oghma, the ancient artifact of the Black Circle, was not destroyed in the icy caves of Andros—Ogron, Duman, Anagan, and Gantlos managed to transfer their essences into the fragments of the dark amulet seconds before its fall. But their powers would not have been sufficient for their resurrection, if not for the colossal magic of another.

A silhouette in a long cloak emerged from the purple mist before them. A man with icy eyes and an arrogant smile held an ancient grimoire. It was Valtor. When Bloom destroyed him with her sacred flame at the end of Season Three, his human form perished, but the spark of the Dark Dragon Fire created by the Ancient Witches returned to its source—the depths of the Magical Dimension itself. He bided his time, gathering his rage.

"You lost to the Winx girls because you were too straightforward," Valtor's velvety voice echoed throughout the dungeon. "You tried to deprive the Earth of faith. Instead, you should have deprived it of its future." "What do you want, demon?" Ogron hissed, his face still a cloud of unstable dark smoke. "The same as you. Revenge. And complete power. My dark fire will restore you to physical form. In exchange, you will give me what you seized on Earth—the White Circle and access to the ancient magic of the Earth fairies. Together, we will create a new order."

The allies struck without warning. Domino was celebrating the anniversary of the planet's liberation from the ice curse. In the midst of the ball, the sky above the kingdom suddenly turned crimson and black. The planet's protective barrier, created by Oritel, burst like a soap bubble.

Bloom, Stella, Flora, Musa, Tecna, and Layla instantly transformed into Believix, ready to repel the attack. But instead of the usual monsters or Trix witches, they were confronted by Mages of the Black Circle. Anagan and Gantlos moved with incredible speed, fueled by a new, strange power—their attacks now carried not only earthly darkness but also searing flame.

"That's impossible! You're frozen in the ice!" Leila shouted, sending Morphix's arrow at Ogron. Ogron absorbed the spell easily, and dark purple sparks danced on his hands. “We were warmed by someone else’s mercy, fairy,” the magician chuckled.

While the Winx and the specialists distracted the Black Circle mages, Bloom felt her heart clench with a sudden, suffocating pain. It was a feeling she hadn't experienced since her training at Alfea. The familiar, yet terrifyingly dangerous call of the Dragon Fire. She turned sharply toward the royal throne.

There, right in front of her parents, bound by a dark spell, stood Valtor. He held Agador's box in his hand, now glowing with the energy of the White Circle.

"Hello, Bloom," he said softly, adjusting his cuffs. "Missing some real competition?"

Bloom tried to attack, but Valtor simply raised his hand, and a wave of dark flame sent her flying back. The Black Circle mages and Valtor weren't planning to destroy the planet right now. Their goal was to make a name for themselves and take Domino's main artifact—the Heart of Flame, the kingdom's protective crystal. Having secured it, Valtor and Ogron vanished through the portal, leaving Domino immersed in eternal twilight and the Winx in absolute shock.

As the portal slammed shut behind the enemies, the crimson sky above Domino slowly returned to its natural color, but the Heart of Flame vanished. King Oritel and Queen Marion sank limply onto the throne—Valtor's spell had lifted, but they were too exhausted. Bloom breathed heavily, clenching her fists.

"He's back..." she whispered, not believing her own eyes. "And they're connected somehow. But how? The mages were on Andros, and Valtor..." "Tecna, did you manage to detect their teleportation?" Stella ran up to her friend, helping her up after Gantlos's attack. "The physical trace is masked by high-level illusion magic," Tecna replied, bringing up a hologram on her PDA. "But Ogron's energy signature left an ionic trail. They didn't travel to Earth or Magix. The coordinates point to Relix... or rather, to the coordinates of Lord Darkar's old castle!"

At that moment, Tecna's PDA flashed red. Roxy's frightened face appeared on the screen. She was calling from Gardenia, from the Winx Pet Shop. "Girls! Can you hear me?!" Roxy screamed through the static. "Something terrible is happening on Earth! The white circle I was guarding started pulsating with black light and simply evaporated! And the animals... they've all gone crazy, they sense some ancient darkness approaching! I'm scared!" "Roxy, don't panic!" Bloom stepped decisively toward the screen. "The Black Circle mages survived, and they've allied with Valtor. Your White Circle is theirs now. We'll take you right now; it's too dangerous to stay on Earth alone!"

Using Layla's portal, the Winx instantly transported Roxy to Domino. The young animal fairy trembled, but her eyes blazed with determination: the mages of the Black Circle had tormented her and the Earth fairies for too long, and she had no intention of hiding.

"We'll head to Darkar's lair right now," Bloom said firmly, activating Believix's wings. "Specialists will remain to protect Domino in case of a second attack. This is a personal matter for the Winx fairies to settle."

Lord Darkar's castle greeted them with deathly silence and the smell of sulfur. The enormous stone halls, once a citadel of evil, were now coated in purple crystals of Dark Fire. The Winx and Roxy carefully navigated the corridors until they reached the main throne room, where the Alfea Codex once stood.

There, in the center of the hall, the stolen Heart of Domino's Flame levitated. Valtor sat on a ruined stone throne, idly flipping through the pages of his book. The Mages of the Black Circle stood around the crystal, forming a ring. The black energy of Ogron's White Circle slowly flowed into the Domino crystal, corrupting it.

"I told you, Ogron, they'll come on their own," Valtor drawled, not looking up from his book. "The Winx girls are so predictable. Especially you, Bloom." "Enough talk!" Leila shouted, and was the first to attack. " Morphix Disc! "

A furious, chaotic fight instantly erupted in the hall. But the enemies were twice as strong. Anagan evaded Musa's attack at breakneck speed, knocking her off her feet with a sonic blast he'd intercepted from Gantlos. Flora attempted to grow poisonous vines to bind Duman, but with a savage roar, he transformed into a massive, fiery, winged lizard—Valtor's magic allowed him to assume the forms of Dark Fire-breathing creatures. He burned the vines with a single breath.

" Light Bolt! " Stella tried to blind Ogron, but the Black Circle mage simply thrust his hand forward. A barrier created from Valtor's magic ignited on his palm. It didn't just absorb Stella's light; it reflected it back as black lightning, throwing Stella and Tecna against the wall.

Valtor slowly rose from his throne, his body enveloped in the purple outline of Dragon Fire. Bloom took flight, gathering all her Believix energy:

• Fire arrow!

Two flames—Bloom's pristine and Valtor's tainted and dark—clashed in the center of the hall. A powerful shockwave erupted, shaking the castle's stone vaults. Bloom gritted her teeth, feeling Valtor draining her strength through this mental contact.

At that moment, Ogron noticed Roxy, who was staying a little behind, trying to protect her wounded friends. "Little last fairy of Earth..." Ogron hissed, directing a stream of destructive dark magic at her. "Your mission is complete."

"No!" Roxy didn't back down. A fury for all the fairies on Earth awoke within her. She thrust her hands forward, activating her Believix power. " Wildwind Pack! "

Instead of ordinary earthly birds, her magic wove ghostly, gigantic shadow wolves and eagles, the kind that had inhabited these dungeons for centuries. They rushed at Ogron with a scream, breaking his magical concentration. This distracted the Black Circle, and Valtor's power weakened.

Bloom took advantage of the enemy's momentary hesitation, increased her pressure, and pushed Valtor back with a powerful blast. But Valtor only laughed, wiping a drop of blood from his lips.

"Not a bad start, fairies," he grinned, gesturing to the mages. "But this round is ours. We got what we wanted."

Ogron slammed his fist into the floor. Darkar's castle shook. The Domino Flame's heart, having completely engulfed the darkness of the White Circle, erupted in a blinding black explosion. The Winx and Roxy closed their eyes, shielding themselves with their wings, and when the smoke cleared, Valtor, the Black Circle Mages, and the corrupted crystal had vanished. All that remained on the floor was a scorched pentagram, the symbol of Valtor intertwined with the Black Circle.

The enemy left, becoming practically invincible, and the Winx realized that the old Believix magic would no longer work against this alliance.
