Lionel demands an explanation for Darius’s return. Darius taunts Lionel, telling him that Tory resurrected him and warning that the Vegas are coming.

Lionel shifts into Dragon form and unleashes fire. Darius throws up an ice shield while Max bolsters it with air, but Max is distracted by intense psychic agony pulling at him from elsewhere in the palace. Tharix confirms he can hear it too, calling it “salvation.” When Darius demands that Tharix make a path, Tharix plunges the room into darkness and whispers for them to run. Max grabs Darius and races toward the source of pain, colliding with the young girl. Sensing her shattered, empty soul, he tells Darius to bring her. They flee through a doorway and up the stairs. Max cannot bring himself to use the stardust to get them away yet, consumed by his need to reach whatever is suffering.

Darcy and Tory fight Lavinia without success. They realize they are exhausting themselves while Lavinia seems tireless. Horror floods through the twins as they accept they cannot defeat her. They vow to fight to the end together. Lavinia unleashes a massive blast. The twins send fire to meet it, but it is instantly snuffed out. With no escape and darkness falling around them, they embrace, preparing to die together.

Max, Darius, and the girl reach a wide chamber with a gaping chasm. Max crawls to the edge and looks down at a bright, pure star lashed in shadows and screaming for release. Lionel’s men close in behind them.

The star pleads to be released, but Max doesn’t know how. He begins singing a Siren lullaby, a song bound with magic potent enough to cast a Fae into a hundred-year sleep. As the melody washes over the trapped star, its screams finally fade. Max takes out the stardust and throws it over himself, Darius, and the girl, whisking them away into the night.

Just before Lavinia’s blast hits Darcy and Tory, her power suddenly stutters and dies. Darcy races forward with fire, but Lavinia shrieks, takes stardust from her pocket, and disappears.

With Lavinia’s power gone, the tide turns quickly. Lionel’s followers retreat via stardust or are chased off campus. Tory and Darcy land atop the Earth Observatory. Darcy spots Orion and the Shadow Beast and leaps down. She and Orion kiss as he sends healing magic through her. Though the battle is won, Darcy knows the war is far from over, especially if Lavinia returns with that terrible power restored.

Less than an hour after the battle, the council assembles in The Orb. Darius reveals that Lavinia’s power came from a fallen star. He and Max recount infiltrating Lionel’s stronghold and discovering Clydinius and the fallen star lashed in shadows.

The young girl with them confirms that Clydinius appeared as the Vega twins and destroyed the Nebula Inquisition Centre where she was held. She reveals that Clydinius and Lionel visited The Ferryman, seeking to cheat death, but he refused them. Gabriel suggests allying with the stars against Clydinius. Darcy proposes freeing the trapped star. Gabriel estimates they have a week or so before the star awakens and Lavinia regains use of its power.

The council makes plans: Darcy and Gabriel hint at a secret solution to combat Nymph rattles; they decide they will hit all remaining Nebula Inquisition Centres simultaneously to free the prisoners and recruit them to the rebels’ cause; Tyler will increase propaganda. They acknowledge that the Bonded Men remain nearly insurmountable.

Orion points out the disturbing bloodlust Tory and Darius have shown since Darius’s resurrection. Tory admits it is the price for using ether to steal Darius from death, and they agree to visit The Ferryman to learn more.

Darcy helps Geraldine overcome her fear of the Shadow Beast. When asked his star name, the creature mentally tells Darcy it is Excaverinias-helios-dolianco; they settle on calling him Shadow. Geraldine updates Darcy on escape drills to flee to Rump Island if Lavinia’s power returns.

Darcy shares a romantic moment with Orion before he carries her to their apartment to change for her mission. When Tory arrives, Orion gives her a bracelet he made with Darcy’s help to commemorate their growing friendship.

Darcy and Tory stardust to a hidden Nymph village, where the new High Nymph, Cordette, refuses their alliance. Darcy speaks of her deceased Nymph friend, Diego Polaris and presents his hat. Miguel immediately recognizes it as Diego’s “soul garment,” which holds his soul. Moved, Miguel takes it, and Cordette agrees to consider what it reveals.

To get more information about the Guild Stones, the twins then visit the Oracles: three Nymph sisters named Vidi, Loqui, and Audire, who demand pain and blood as payment. They reveal that the 12 Guild Stones can create a “snare” but require “bait.” They cryptically tell Darcy she has already spoken the answer to how it works. Outside, they meet Karim, a Nymph who reveals a secret rebel group within the village. They want to fight but are unable to leave without Cordette’s permission. He pledges allegiance and gives Darcy a wooden totem as a vow.

Lionel travels across the sea on air magic with his Bonded Men, court, Lavinia, Tharix, and Clydinius. He recognizes Lavinia’s power as a problem to manage through cunning. He considers Clydinius the truest threat but hopes to weaponize him, planning to ask for immortality as his reward for helping Clydinius join with two other stars to achieve the Celestial Trinity and limitless power. He notes Tharix seems vacant and plans to discipline him, and he dwells on Darius’s impossible resurrection and the fallen star being rendered useless.

Vard locates the concealed Academy of Hydros underwater, and they attack. Lionel attempts to tear through the protective wards but is thrown into the ocean, humiliated. He believes Tharix sniggers and promises to punish him. Clydinius waves a hand, bringing the wards down and revealing the academy’s castle. He begins ripping Fae from the castle and throwing them into the water. Lionel watches with awe and trepidation, becoming certain he must find a way to possess Clydinius’s power.

Darius waits in his room at Ignis House for Tory to return from the Nymph mission. When she arrives near four in the morning, she explains the results: The High Nymph refused, but a rebel group wants to fight.

Darius goes to The Orb to fetch food and returns to find Tory asleep in his jacuzzi tub. He gently washes her hair while she dozes, and they share a tender conversation. Darius carries her to bed for passionate sex. Afterward, Tory tells him she loves him. Darius replies that he loved her first, holding her close.

Caleb runs through The Wailing Wood early in the morning and sees his brother Hadley and Seth’s sister Athena, a Wolf shifter. They reveal they are working with Xavier and Grayson to build a defuser weapon designed to disable Lionel’s magical weapons.

Caleb continues to a hidden cavern to meet with Orion. Orion has brought old scrolls and a forbidden ancient book titled Of Coven Lore, detailing illegal Vampire coven practices. They discuss the ethical risks of using the book—reading it breaks the law, but they need its knowledge. They swear a star-bound oath: They will use the knowledge only to win the war, and once Lionel is dead, they will forget everything and never use it again. With the oath binding them, Caleb opens the forbidden book.

Xavier trains in the Pitball stadium, but rage over his father clouds his focus. Orion tells him to channel focus instead of anger. Xavier successfully uses ice magic to trap Orion and lands a hit, regaining confidence.

Afterward, Xavier confides to Darius that since he and their mother died, he has been unable to finish during sex due to grief and guilt over surviving. Darius reassures him that their mother died for them willingly and insists Xavier deserves to live—he was the reason Darius resisted their father. They share a powerful moment of brotherly love.

Xavier, Darius, the twins, and their Councillors then stardust to a barren mountain overlooking Lionel’s massive army encampment. They cast a large-scale illusion of a rebel army marching into the valley to distract Lionel’s forces while their allies liberate all of his Nebula Inquisition Centres.

Orion and Max are tasked with breaking out captives from the Sunshine Bay Nebula Inquisition Centre. They go to the first of six watchtowers surrounding the sea-based prison, where 20 large nets hold water-reliant Orders captive. Max sings a powerful ocean song that raises a massive wave, shattering the wards. Orion creates a storm that topples all six watchtowers, sending guards falling into the nets where liberated Sharks and sea creatures attack them.

They swim to each net, freeing all prisoners. Orion amplifies his voice, inviting all to join the rebel army. Orion and Max share a moment of victory.

Tory stands on the mountain watching the illusory rebel army march toward Lionel’s encampment. She reveals to Darius that she and Darcy have a separate mission, and his Dragon form is too large to follow. Before he can stop her, she falls backward into a narrow chasm.

The twins fly through the razor-sharp ravine and proceed through cold tunnels using concealment spells. Plaques bear strange names like Smittony and Roarkarlow—Lionel is keeping more of the monstrous creatures that have been created. Despite their horror, they decide the star is the greater priority.

As they approach the exit, Clydinius stands before them—skin a wan gray, aura utterly empty. The twins freeze beneath their concealment spells, but Tory fears none of their magic will work on a star given form. Clydinius’s attention begins shifting toward them as they realize they have walked straight into the path of the creature whose curse nearly ended their family line.

Seth, in Wolf form, carries Caleb toward Lionel’s new diamond mine in the Polar Capital. They observe a vast quarry where prisoners, including chained Polar Bear shifters, are forced to mine under guards from the King’s United Nebula Taskforce (K.U.N.T.).

Seth uses earth magic to send a massive blast underground, crushing the weapon that controls the prisoners. He leaps into the quarry fighting while Caleb speeds through at Vampire pace, breaking chains on the Polar Bear shifters. The miners rise up, overpowering their captors, and they invite the freed Fae to join the Vegas and the rebellion. A Polar Bear shifter named Imenia Brumalis introduces herself as a member of the Glacials, pledges allegiance to the True Queens, and offers a powerful glacia diamond shimmering with northern lights colors to assist in the war.

Leon, Gabriel, and Geraldine travel to liberate a Nebula Inquisition camp where Fae are held in tree-hung cages guarded by Nymphs and K.U.N.T. officers. As they prepare to attack, a highly poisonous galad frog lands on Leon. The poison causes wild hallucinations. He dances and fights imaginary enemies, mostly ineffective in actual battle, before blacking out.

Leon wakes in the boat after the battle, sick and disoriented. Gabriel informs him that all prisoners have been freed and recruited. Gabriel confirms that the other missions were also successful.

Darcy and Tory remain hidden as Clydinius whispers in the language of the stars, then turns and walks into the palace without noticing them. They follow him up a stairway to a cavern with a gaping chasm that holds the captive star. He blasts the fallen star, Esvellian, with starfire to wake her. Esvellian screams in agony, creating a painful tether to the twins’ souls. Clydinius tries to convince her to join him in forming a Trinity to rule over mortals, but Esvellian refuses. Vard arrives, announcing Lionel needs Clydinius for an approaching army. Clydinius departs.

After Vard leaves, the twins fly into the pit. They burn away Esvellian’s shadow bindings with Phoenix fire. In return, Esvellian cleanses the shadows, freeing all trapped souls.

Her power washes through the twins and out into the world, giving them clarity about love being life’s true purpose. Lavinia’s furious shriek echoes distantly as she feels the shadows cleansed and her power lost. The twins realize the Nymphs are now free to join them; without Esvellian’s power, Lavinia is no longer invincible.

Darius and Xavier maintain the illusory army. It has been almost an hour since the twins jumped into the ravine. He wants desperately to follow but knows his Dragon form cannot navigate the narrow chasm. Xavier reminds him that abandoning the illusion could expose the twins to greater danger.

Tharix suddenly appears behind them. He speaks cryptically about bloodshed being the price for Darius’s return, claiming he heard it from the water or The Ferryman. He questions their concepts of good and bad, asking if being born from a rotten tree makes him rotten. Darius insists choices make the man, and Tharix decides to test this by making no choice at all. He steps backward into the ravine and disappears.

Darius is consumed with worry for Tory, but her steady pulse tells him she lives. Xavier convinces him to stick to their plan and maintain the illusion, as its success is critical to all simultaneous missions.
