The Idris dawn was a fragile thing, its pale light filtering through the glass towers and casting long shadows across the Institute's courtyard. The air was crisp, scented with pine and the faint tang of rune-etched stone, a stark contrast to the sulfurous heat of Asmodeus's realm. My arm still ached from the Unity rune's scar, a jagged reminder of the fire that had grazed me, the sacrifice that had saved Kyle but bound me closer to the Binding Rune's volatile power. The pendant around my neck hummed softly, its crescent moon rune a quiet pulse, tethering me to Elara's legacy and Mira's survival. Mira sat beside me on a stone bench, her small frame bundled in a borrowed Shadowhunter jacket, her knife tucked into her belt, her eyes bright but haunted. She was here, safe for now, but the memory of her strapped to Malachi's table, her blood fueling Asmodeus's portals, was a wound that wouldn't heal.
The Institute buzzed with tension, Shadowhunters moving with purpose, their black gear a somber contrast to Idris's radiance. Aldertree's treason had shattered the Clave's unity, his red rune and Asmodeus's allegiance exposing a rot within their ranks. Whispers of distrust echoed in the halls, and Maryse's face, usually a mask of control, was lined with exhaustion as she coordinated defenses. Alec, recovered but pale, trained with Jace and Clary, his bow steady but his eyes shadowed by the possession's memory. Isabelle, ever fierce, sharpened her whip, her laughter a defiant spark in the gloom. Catarina Loss and Magnus Bane worked in the library, poring over Elara's journal, seeking answers to the Return rune—a faint hope against Asmodeus's inevitable retaliation.
I clutched the journal, its pages worn but alive with Elara's runes and notes, the Return rune a complex spiral of light and shadow, promising to seal Asmodeus's portals but at a cost I didn't yet understand. Tessa Gray's words in the realm lingered: *"It's tied you to him, Lilia. Every use draws him closer."* The thought sent a chill through me, but Mira's hand in mine, her quiet strength, was a reminder of why I fought.
"Lilia," Mira said, her voice soft but steady, "you're gonna save everyone, right? Like you saved me?"
I forced a smile, brushing a strand of hair from her face. "I'm trying," I said, my voice thick. "But I need you to stay strong, okay? No more running into alleys with knives."
She grinned, a spark of her old mischief. "No promises," she said, echoing my words to Kyle, and I laughed, the sound a fleeting release.
Kyle approached, his daggers sheathed, his dark hair tousled by the breeze. The graze of Asmodeus's fire had left a faint scar on his cheek, a mirror to mine, and his eyes held a weight that hadn't been there before—guilt, perhaps, for the moment I'd pushed him from harm. "You two plotting a rebellion?" he asked, his voice light but his gaze heavy, lingering on me.
"Just surviving," I said, my heart stuttering under his intensity. Our kiss in the realm, fierce and desperate, had shifted something between us, a bond deeper than survival, but Aldertree's accusations—his claim that Kyle's father's treason tainted him—cast a shadow, and I wondered if the Clave's distrust would fracture us.
Before he could reply, Maryse called us to the war room, her voice sharp. "We have a problem," she said as we gathered, her eyes scanning the team—Mira, Kyle, Isabelle, Alec, Jace, Clary, Lydia, Catarina, Magnus, and Tessa. "Portals are opening across Idris, small but unstable, spitting demons. Asmodeus is testing our defenses, and the Clave's divided. Some still believe Aldertree was framed."
Lydia's jaw tightened, her Clave loyalty warring with her actions in Panem. "They're wrong," she said. "I saw his rune, his allegiance. But the council's calling for Lilia's trial—again. They think her rune's causing the breaches."
My stomach twisted, the pendant flaring. "They're blaming me for Asmodeus?" I said, my voice sharp. "After everything?"
Kyle's hand brushed mine, a silent support, but his eyes were dark. "They're scared," he said. "And scared people make stupid choices."
Magnus smirked, tossing a glittering ring into the air. "Stupid is the Clave's specialty," he said. "But Tessa and I found something in Elara's journal—a relic, hidden in Panem, tied to the Return rune. It could seal Asmodeus's realm permanently."
Tessa nodded, opening the journal to a sketch of a crystal orb, its surface etched with runes. "The Orb of Seraphiel," she said. "Elara hid it in District 12's mines, protected by angelic wards. It amplifies the Return rune, but retrieving it means facing the Capitol's remnants—and Asmodeus's spies."
Mira's eyes widened, her hand tightening on her knife. "I know those mines," she said. "I can help."
"No," I said, my voice firm. "You're staying here, where it's safe."
Her face hardened, a stubbornness I recognized. "I'm not a baby, Lilia," she said. "I fought Peacekeepers. I can fight this."
Catarina's hand rested on Mira's shoulder, her blue eyes gentle. "She's right," she said. "Mira's tied to you, to the rune. Elara's blood runs in her too. She might sense the orb where we can't."
I hesitated, fear clawing my chest, but Mira's resolve was a mirror to mine, and I nodded, reluctant but proud. "Fine," I said. "But you stay close, and you listen."
Kyle's eyes met mine, a flicker of admiration in their depths, but before he could speak, an alarm blared, the war room's runes flaring red. "Breach!" Alec shouted, his bow drawn, and the ground shook, a portal tearing open in the courtyard, spitting Shax demons and a new horror—Ravener demons, their segmented bodies and venomous tails glinting in the dawn.
The courtyard became a battlefield, Shadowhunters pouring from the Institute, their seraph blades glowing with angelic light. Isabelle's whip cracked, slicing a Shax demon's throat, black ichor spraying. Alec's arrows flew, each tipped with runes that burned through demonic flesh. Jace and Clary fought as a unit, their blades a blur, while Lydia's precision cut down a Ravener's tail. Magnus's magic erupted, a storm of blue fire that scattered the smaller demons, and Tessa wove runes, her bracelet glowing, creating barriers to protect the younger Shadowhunters.
I drew Speed and Strength, my sword a familiar weight, and fought beside Kyle, his daggers a deadly dance. Mira stayed behind me, her knife slashing at a Shax demon's claw, her movements clumsy but fierce. "Stay back!" I shouted, cutting down the demon, but her eyes blazed, Elara's defiance in her blood.
"Lilia, the portal!" Magnus called, his voice strained as he held a barrier against a Ravener's venom. I ran, drawing the Binding Rune, its glow clashing with the portal's red light. The energy surged, the portal flickering, but a new figure emerged—a Shadowhunter, her face familiar, her eyes glowing red, a demonic rune on her neck. Imogen Herondale, a Clave elder, possessed like Alec had been.
"She's one of ours!" Maryse shouted, her whip faltering, but Imogen's blade struck, forcing her back. Kyle tackled her, his daggers pinning her arms, but her strength was demonic, throwing him off. I drew Harmony, its cool glow steadying me, and touched Imogen's chest, the Binding Rune's energy surging. Pain lanced through me, but her rune cracked, ichor oozing, and her eyes cleared, her body collapsing.
"Another possession," Catarina said, her voice grim, tending to Imogen. "Asmodeus is targeting the Clave's leaders."
The portal closed, the demons thinning, but the courtyard was a wreck, bodies and ichor staining the stone. Maryse's face was pale, her voice sharp. "We can't stay here," she said. "The Clave's compromised. We need the orb, now."
I nodded, my heart racing, Mira's hand in mine. "District 12," I said. "We go tonight."
Kyle's eyes met mine, his scar a stark line in the dawn. "I'm with you," he said, but a Clave enforcer approached, his face grim, a scroll in hand.
"Kyle Wayland," he said, "you're under arrest. Evidence suggests you aided Aldertree's treason."
My blood ran cold, Kyle's face hardening. "That's a lie," he said, his voice low, but the enforcer's blade was drawn, and Lydia stepped forward, her eyes conflicted.
"It's an order," she said, her voice quiet. "Until we investigate."
Isabelle's whip cracked, her voice fierce. "You're not taking him," she said, but Kyle raised a hand, his eyes on me.
"Go," he said, his voice steady. "Get the orb, save Mira. I'll handle this."
I grabbed his hand, my voice breaking. "I'm not leaving you."
"You have to," he said, his thumb brushing my scar, his eyes raw. "For her."
The enforcers took him, his daggers confiscated, and my heart shattered, the pendant's burn a mirror to my rage. Asmodeus was tearing us apart, and the Clave's blindness was his weapon.
The portal to District 12 was a desperate gamble, Magnus's magic strained, my Binding Rune stabilizing its edges. We emerged in the Seam's outskirts, the mines a looming shadow under a moonless sky. Mira led the way, her knowledge of the tunnels a guide, while Isabelle, Alec, Tessa, and I followed, our weapons ready. Magnus stayed behind, guarding Idris with Catarina, their magic needed against new breaches. Lydia, torn by Kyle's arrest, joined us, her blade a quiet vow to prove his innocence.
The mines were a labyrinth of damp stone and creaking supports, the air thick with coal dust, memories of my childhood—Elara's stories, Mira's laughter—clashing with the present's dread. The pendant hummed, guiding us to a hidden chamber, its walls etched with angelic wards that glowed faintly. At its center was the Orb of Seraphiel, a crystal sphere pulsing with light, its runes a mirror to Elara's journal.
Mira's eyes widened, her hand reaching out, and the orb flared, a rune appearing on her palm—Clarity, a symbol of truth. "It knows me," she whispered, and I realized Elara's blood had gifted her a power of her own, a strength Asmodeus hadn't anticipated.
But as we took the orb, the chamber shook, a portal tearing open, spitting Peacekeepers with red runes and a new warlock—Seraphina, her silver hair and glowing eyes a mirror to Malachi's cruelty. "The orb is ours," she said, her voice a hiss, and the fight began.
Isabelle's whip cracked, Alec's arrows flew, Lydia's blade danced, but Seraphina's magic was a storm, her red runes countering ours. I drew the Return rune, its spiral glowing, and the orb flared, amplifying its power. The portal shuddered, weakening, but Seraphina's magic surged, a red rune pinning me to the wall, pain searing my chest.
Mira screamed, her Clarity rune glowing, and a burst of light shattered Seraphina's spell, freeing me. "You're not taking her!" Mira shouted, her knife slashing, and I drew Unity, its starburst clashing with Seraphina's runes. The orb's light surged, the portal collapsing, and Seraphina retreated, her scream echoing as the chamber stabilized.
We escaped, the orb in Tessa's hands, but the pendant flared, a vision hitting me—Kyle, in a Clave cell, his eyes glowing red, possessed. "No," I whispered, my heart breaking, and Tessa's face hardened.
"Asmodeus," she said. "He's targeting those closest to you."
Back in Idris, the Clave was a warzone, portals opening, demons flooding the streets. Magnus and Catarina fought, their magic a beacon, while Maryse rallied the Shadowhunters, her whip a storm. I clutched the orb, the Return rune glowing, and Mira's Clarity rune guided us to the council chamber, its runes dim but alive.
"We need to save Kyle," I said, my voice fierce, but Tessa revealed the journal's final secret—a relic's price. "The orb requires a sacrifice," she said. "To seal Asmodeus's realm, you must give up something vital—your connection to the Shadow World, or someone you love."
My heart stopped, Mira's hand tightening, Kyle's face vivid in my mind. "There has to be another way," I said, but Tessa's eyes were grim.
"Elara chose you over herself," she said. "You must choose now."
We fought to the cells, demons falling to our blades, the orb's light a beacon. Kyle was there, his possession fading under the Return rune's glow, but Asmodeus's voice echoed, a final taunt. "Choose, Lilia," he said, and I drew the rune, the orb flaring, its light sealing the portals but tearing at my soul.
Kyle's eyes cleared, his hand finding mine, but the orb's price surged, and I screamed, the Shadow World fading, Panem's ash replacing it. I was home, Mira at my side, but Kyle was gone, trapped in Idris, and the pendant's burn was a vow—I'd find him, no matter the cost.
