Xavier and Darius maintain the illusion of the rebel army as Lionel’s forces close in. As soldiers charge and discover the illusion, the Councillors signal retreat, giving Xavier and Darius time to run.

As Lionel flies toward them, monsters arrive at the rear of his army. Ignoring the chaos, Lionel continues his assault, but Tory and Darcy block his fire. Darius uses stardust to teleport everyone back to Zodiac Academy, where the twins confirm they freed the star, and it cleaned the shadows.

They enter The Orb to a hero’s welcome. Orion and Darcy reunite passionately. Xavier reunites with Sofia and Tyler, and they return to his room. After they have sex, Xavier finally overcomes his inability to orgasm and loudly celebrates. Geraldine knocks on the door, warning them that they are livestreaming, and Xavier is mortified. They read humorous comments, including one from Gabriel admitting he foresaw this and allowed it as revenge.

Lionel crashes into his castle, injured. His hand, which he lost and Lavinia replaced with shadow, is failing and causing agony. Linda Rigel informs him that the rebels have destroyed all Nebula Inquisition Centres and freed the prisoners. His shadow hand vanishes completely.

Lavinia tells him that she can no longer hear the souls whispering (the result of Esvallian’s work). Realizing her power has diminished, he forces her into a Guardian Bond, branding her and making her subservient to him. Lavinia’s Capricorn sign appears in black shadow on his skin.

When they realize that the shadows are gone, they go to the pit where his captive star was kept. Tharix confirms the star was freed, not stolen, completing its life cycle, and he reveals he no longer hears Lavinia’s whispers.

The Imperial Star Clydinius appears, furious that the star promised for his Trinity is gone. Lionel blames the Vega twins and promises Clydinius the next star that falls.

The rebel army celebrates with a bonfire in The Wailing Wood. Darius sits apart, feeling it too soon to celebrate. Orion arrives and mentions Geraldine’s plan for a live broadcast to recruit Fae to the rebellion. Darius reads Tyler’s sensationalized article about his resurrection, noting an obsessive comment from Cindy-Lou Galaxa that triggers vague recognition.

Orion voices concern about Tory and Darius’s bloodlust curse. Darius says Tory has a secret plan involving their upcoming meeting with The Ferryman. From the dance floor, Roxy teases Darius. Later, she beckons him, and he follows her into the woods. Their power play turns into rough, passionate sex against a tree.

At dawn, Orion meets Darius, who reluctantly gives Orion a sapphire ring from Luxie Acrux’s hoard for proposing to Darcy. Caleb arrives as invited, bringing Seth. Orion asks each friend to add magic to the ring, and other friends, including Geraldine, Max, Xavier, Sofia, and Tyler, arrive. Tory arrives, gives her blessing, and adds a Gemini symbol to the ring. Orion leaves the ring in Gabriel’s care.

Later, Orion and Darcy visit the Venus Library archives. They read about a Celestial Trinity—a theorized union of three stars that could unravel fate. Darcy finds a passage about using stone circles to wield magic and believes it connects to using the Guild Stones as a snare.

Caleb reflects on the war and his anger at his mother Melinda, a Celestial Councillor, for not stopping Lionel sooner. Walking through the rebel encampment, he observes a new symbol created by the people: two phoenixes rising through a crown. At a vendor’s stall, he purchases a rose-quartz crescent pendant.

Caleb meets his mother on a beach and challenges her for her position as Celestial Councillor. They engage in a long, brutal magical duel until Caleb eventually exploits a pattern in her defense. She proudly yields, and he claims her title.

Caleb races to The Orb, interrupting a live broadcast. He makes a public declaration of love for Seth and gives him the rose-quartz necklace. Seth kisses him passionately on camera, then they leave for King’s Hollow and have sex on a balcony beneath the moon. As they climax, both feel a burning sensation behind their ears and discover matching silver crescent marks—the moon has bonded them as mates.

The next day, Darcy and Tory visit the Nymph village. High Nymph Cordette remains noncommittal about sending warriors but seems impressed that they freed the star. She also reveals that they are more willing to join now that the shadows have been banished. When they return to The Orb, Imenia Brumalis arrives from the Polar Capital. She presents the twins with a powerful Glacia diamond, promising to teach them to wield the Northern Lights.

That night, Darcy has a nightmare about Orion being tortured by Lavinia. Gabriel, having foreseen the nightmare, arrives and takes Darcy and Orion to the ruins of the Palace of Flames, where the rare Nox flower is blooming.

Darcy has a vision showing Avalon forcing 20 followers to die by suicide to power a dark spell. Now, the 20 skeletal Fae rise and attack. Gabriel directs them to retrieve a key from one skeleton’s neck. Darcy gets the key, Gabriel opens the cage around the flower and collects its pollen. Gabriel leaves with the pollen to have it made into a potion for the army.

Gabriel then takes Darcy to the top of Aer Tower, explaining her nightmares stem from protective instincts—she is a Harpy like him. He teaches her his coping mechanism: flying a nightly patrol around the perimeter to calm her fears.

The morning after, Tory is secretly studying the Book of Ether and making notes about runes for an unshared plan for the war. When Darius questions her, she remains evasive. Friends arrive for a war council.

At the war council breakfast, Geraldine reports on army numbers and confirms that Voldrakia will not join the war, though Emperor Adhara sent a gift containing four baby sayer dragons, a species thought extinct. The dragons imprint on Tory and Darcy. Orion explains they are powerful, loyal creatures with unique individual magic. Tory lists their assets but feels they lack enough to win, especially against Clydinius. Seth dismisses the Guild Stones as a failure, offending Orion.

After Orion and Darcy leave to research, Darius suggests turning Tharix to their side, but they set the idea aside for now. Tory and Darius prepare to visit The Ferryman.

Orion and Darcy create a stone circle and are able to use the Guild Stones. They summon the star Arcturus, but he refuses to help them against Clydinius, as he is bound by star laws not to interfere. Darcy insists that he can help them restore balance.

Arcturus warns that if Darcy lies, Orion’s soul pays the price. He magically drowns Orion’s soul until he nearly breaks. After an agonizing ordeal, Arcturus releases Orion, and Darcy tells Orion that Arcturus agreed to help them with no price.

Back on the clifftop, Orion accuses Darcy of lying about the cost to protect him. Darcy insists she told the truth and flies off. Orion follows her to the Pitball stadium, where they have an intense training duel. They have passionate sex on the field. Afterward, she refuses to let him heal his bite marks on her neck, wanting to wear them as a symbol of their publicly accepted bond.

Darius and Tory ride a motorcycle to a blackened hangman’s tree. Tory performs a ritual to forcibly summon The Ferryman.

The Ferryman appears, and they ask about the specific cost of Darius’s resurrection. The Ferryman states that the souls of Lionel Acrux and his army will settle the debt.

As The Ferryman departs, Tory leaps onto his raft. Darius attempts to follow her but falls through the ice. Tory rescues him and reveals that she tried to trade The Ferryman a dagger stained with cursed blood in exchange for his protection for her army. He refused, but she gave it as a gift anyway, hoping to earn goodwill. They agree to ensure they offer The Ferryman plenty of souls when facing Lionel’s army.

Tharix wanders Lionel’s castle, experiencing new physical sensations like cold and pain. Lavinia confronts him in the throne room and tries to connect her shadows to his, but he resists. He walks away, now able to ignore her commands, and avoids his father as well.

A skeletal hand lunges from a puddle, grabs his ankle, and wrenches him to the floor. It forces his face beneath the water, causing him to feel fear for the first time. The skeletal being declares that the four souls trapped within Tharix belong to it, and it has come to reclaim them.

Mildred Canopus, one of Lionel’s Bonded Dragons, is imprisoned at Zodiac Academy. Guards find her weak and take her to the infirmary. On the way, she attacks a guard and steals a golden bracelet that slowly restores her magic. She kills her two guards with wooden spears, using restored magic.

She breaks free, grabs an Atlas, and calls her father to come for her. She then shifts into Dragon form, shattering the infirmary walls. Geraldine Grus bursts in, and Mildred snatches her as a gift for Lionel and escapes through a window.

Darcy and Orion are alerted that Mildred has escaped with Geraldine. The group mobilizes with vehicles. They spot Mildred’s Dragon form flying up a mountainside as a horde of Dragons appears to intercept them. Darcy uses a massive fireball to take down one Dragon, and the others engage in battle to clear a path.

While Darcy drives, Max uses his Siren song to slow Mildred. Mildred flies around a mountain peak, temporarily breaking their line of sight as the pursuit continues.

Tory stops her motorcycle and creates a wall of air magic; two pursuing Dragons collide with it. Another Dragon dives at her, breathing fire. She shifts into Phoenix form and flies into the flames unharmed. Darius shifts into Dragon form and kills the brown Dragon by ripping out its throat.

Tory flies toward a grey Dragon circling Seth’s car. She battles it and kills it, feeding her bloodlust debt to The Ferryman. She sees Darius fighting two Dragons overhead and flies back to join the battle.

Geraldine struggles in Mildred’s claws, determined not to be taken alive. She can hear the battle and is moved that the queens and friends have come to rescue her. She feels the pull of Max’s Siren song. Though Mildred is clearly affected, the Dragon continues to resist. Geraldine draws strength from knowing her friends love her enough to risk everything.

Orion and Caleb fight a red Dragon together and kill it with combined ice and fire magic. Orion sees a blue Dragon pluck Seth’s car from the road and throw it off a cliff. He dives after the falling car, rips the door off, and pulls an unconscious, bleeding Seth out just before it crashes.

Orion pours all his healing magic into Seth, whose heart begins to fail. After a terrifying moment where Seth’s pulse weakens dangerously, his heartbeat strengthens, and he regains consciousness. Caleb arrives, and Seth offers his blood to replenish Orion and Caleb’s magic. The three return to battle together, with Seth shifting into Wolf form.

Max continues his Siren lure, but the road turns from Mildred’s flight path. Darcy loses control on a sharp turn, and the car flips over the cliff edge. Just before impact, Darcy unleashes Phoenix fire, destroying the car but saving them both. She flies them through the air, concealed by illusion, continuing the pursuit.

They both throw ice spears at Mildred’s wings. To dodge, Mildred rolls mid-air and releases Geraldine. Max catches her in a net of air magic. Darcy lowers them to the ground. The others arrive one by one, each holding Geraldine tight. Mildred escapes, and Darcy and Tory declare they are ready for their endgame in the war.
