The Seam's air was a chokehold of ash and despair, the familiar scent of coal dust and hunger wrapping around me like a shroud. District 12's shanties loomed under a bruised sky, their sagging roofs and cracked walls a testament to Panem's cruelty, a world that had shaped me, broken me, and now called me back. The pendant around my neck burned, its crescent moon rune pulsing with a frantic energy, a tether to the Shadow World I'd lost—Idris, the Institute, Kyle. My heart ached at his name, his final words—*"Get the orb, save Mira. I'll handle this"*—a vow shattered by his arrest, his possession, the Clave's betrayal. The Orb of Seraphiel's sacrifice had sealed Asmodeus's portals but torn me from him, stranding me in Panem with Mira, the only light in this ash-choked darkness.
Mira walked beside me, her small frame steady despite the oversized Shadowhunter jacket swallowing her shoulders. Her knife was tucked into her belt, her Clarity rune—a glowing mark of truth on her palm—faint but alive, a gift from Elara's blood that had saved me in the mines. Her eyes, so like our mother's, were fierce, but the shadows beneath them spoke of nightmares, of Malachi's lab, of portals and blood. She was nine, too young for this war, yet her courage mirrored mine, a fire that refused to die.
"Lilia," she said, her voice cutting through the wind's howl, "we're gonna find Kyle, right? And stop the bad guy?"
I forced a smile, my hand tightening on Elara's journal, its pages a lifeline of runes and secrets. "Yeah, kid," I said, my voice thick. "We'll find him. And Asmodeus won't know what hit him."
But the truth was heavier, a stone in my chest. The Return rune, drawn with the orb's power, had banished me to Panem, severing my connection to the Shadow World. Reopening a portal to Idris meant mastering the rune again, but Tessa's warning—*"Every use draws him closer"*—echoed, a reminder that Asmodeus's eyes were on me, his hunger for the Binding Rune unrelenting. And Kyle, possessed in a Clave cell, was a wound I couldn't heal, his scar and kiss a memory that fueled my fight.
The Seam's alleys were a maze, their silence eerie, the usual hum of starvation replaced by a tension that prickled my skin. Peacekeeper patrols had doubled, their red-rune armor glinting in the dawn, their eyes glowing with demonic light. The Capitol hadn't fallen with Malachi's defeat; it had regrouped, its new leader a shadow I hadn't yet faced. Mira's hand slipped into mine, her Clarity rune flaring faintly, and I felt a surge of her strength, a reminder that we were Thorn sisters, forged in fire.
We reached the Hob, District 12's black market, its stalls half-empty but alive with whispers. A woman with gray hair and sharp eyes—Tessa Gray—emerged from the crowd, her rune-etched bracelet glinting, her presence a quiet anchor. She'd followed us through a hidden portal, her warlock magic a bridge between worlds, and her knowledge of Elara's plans was our only hope.
"Lilia, Mira," she said, her voice calm but urgent, "the Capitol's new warlock, Vespera, is rallying forces in District 13's ruins. She's Asmodeus's new lieutenant, weaving red runes stronger than Malachi's. They're hunting you—and the orb."
I clutched the Orb of Seraphiel, its crystal surface warm in my pack, its runes pulsing in sync with my pendant. "What does she want?" I asked, though I dreaded the answer.
Tessa's eyes darkened. "The Binding Rune," she said. "Vespera believes it can merge Panem and Asmodeus's realm, creating a dominion under her control. Mira's blood, your blood, is the catalyst. And there's a resistance in District 13, fighting back, but they need you."
Mira's Clarity rune flared, her voice steady. "I can help," she said. "I felt the orb. I can feel them too."
I hesitated, fear clawing my chest, but Tessa nodded. "She's right," she said. "Elara's blood runs in her. Her Clarity rune can guide us to the resistance, and your Return rune can get us to Kyle."
The thought of Kyle, his eyes red with possession, spurred me forward. "Then we move," I said, my stele steady in my hand. "But I need to train the Return rune. If it's tied to Asmodeus, I can't lose control."
Tessa led us to a hidden safehouse, a crumbling shack with rune-etched walls, its interior lit by a single fire. The journal lay open, the Return rune's spiral a challenge, and as Mira slept, her small form curled by the fire, I began to learn, Tessa's guidance a lifeline in the dark.
The safehouse was a crucible, its confines a battleground of will and power. Tessa stood beside me, her bracelet glowing, as I drew the Return rune on a wooden beam, its spiral softer but sharper with each attempt. The Binding Rune on my arm burned, its jagged star a constant pulse, and the orb's light amplified both, a symphony of angelic and demonic energy that threatened to overwhelm. My scar from the Unity rune ached, a reminder of the realm's fire, and every stroke of the stele felt like a gamble, a step closer to Asmodeus's gaze.
"Focus on Kyle," Tessa said, her voice steady. "Not his possession, but his strength, his loyalty. The rune responds to your intent."
I closed my eyes, summoning memories—Kyle's hand in mine, his scar matching mine, his kiss in the realm, fierce and tender, a vow against the dark. The stele moved, the Return rune glowing, and the safehouse hummed, the air shimmering with a radiant light. The beam didn't splinter, the energy didn't lash out, and Tessa's nod was a rare approval.
"You're closer," she said. "But the rune's tied to your blood, your soul. To open a portal, you'll need to give part of yourself—maybe more than you can spare."
I swallowed, the pendant searing my chest. "For Kyle, for Mira, I'll give anything," I said, my voice fierce.
Mira stirred, her Clarity rune glowing, and she joined us, her small hand tracing the journal's runes. "I can help," she said, and to my shock, she drew Clarity on the beam, its light merging with the Return rune, stabilizing it. The orb flared, and a faint portal flickered, its edges crackling but steady, a glimpse of Idris's towers beyond.
"You're incredible," I said, pulling her into a hug, pride swelling despite my fear. But the pendant flared, and a vision hit me, vivid and merciless.
I saw Kyle, in a Clave cell, his body thrashing, his eyes red, a demonic rune pulsing on his chest. Asmodeus's voice echoed, a storm of fire. "The boy is mine," he said, "and through him, I'll claim the rune." But Kyle's hand twitched, a faint rune glowing on his palm—Resilience, a symbol of defiance, a power I hadn't known he possessed.
The vision shifted to District 13's ruins, a resistance camp hidden in bunkers, led by a woman with scars and a steely gaze—Katniss Everdeen, a name whispered in the Hob. Her bow was drawn, her allies wielding stolen Peacekeeper weapons, but Vespera's red runes glowed, her demonic army advancing.
I snapped back, gasping, Tessa's hands steadying me. "Kyle's fighting," I said, my voice trembling. "He has a rune—Resilience. And there's a resistance in District 13, led by someone named Katniss."
Tessa's eyes widened. "Katniss Everdeen," she said. "She's a survivor, like you. Elara knew her, trusted her. If she's fighting, we have a chance."
Mira's Clarity rune glowed, her voice urgent. "I can find her," she said. "I feel her, like the orb."
I nodded, my resolve steel. "We go to District 13," I said. "We join the resistance, get the portal open, save Kyle."
But as we prepared, the safehouse shook, a red rune flaring on the walls, and Peacekeepers stormed in, their eyes glowing, their armor pulsing with Vespera's magic. The fight was immediate, my sword flashing, Tessa's runes a barrier, Mira's knife slashing with a courage that broke my heart. We escaped, the safehouse burning, and headed for District 13, the orb a beacon, the pendant a warning.
District 13's ruins were a graveyard of concrete and steel, its bunkers hidden beneath rubble, the air thick with the scent of rust and rebellion. Mira's Clarity rune guided us, her small frame navigating the wreckage with a certainty that awed me. Tessa's glamour cloaked us from Peacekeeper patrols, but the pendant's hum grew louder, a beacon Vespera could sense. We reached a fortified bunker, its entrance guarded by rebels with scarred faces and stolen weapons, their eyes wary but hopeful.
Katniss Everdeen met us, her braid tight, her bow slung across her back, her presence a spark in the gloom. "You're the Thorn sisters," she said, her voice steady but sharp. "Tessa said you'd come. We're fighting the Capitol's new warlock, Vespera. She's turning our people into demons."
I nodded, the orb heavy in my pack. "We have a weapon," I said, "but we need to open a portal to Idris. My—our friend is trapped there, possessed."
Katniss's eyes softened, a flicker of understanding. "We've lost people too," she said. "Join us, and we'll help you."
The bunker was a hive of activity, rebels training, medics tending wounds, maps strewn across tables. A man with kind eyes—Peeta Mellark—offered us bread, his hands steady despite the scars, and a woman with sharp features—Johanna Mason—sharpened an axe, her grin fierce. They were survivors, like us, and their fight was ours.
Mira's Clarity rune flared, guiding us to a hidden chamber where rebels stored rune-etched weapons, stolen from the Capitol's labs. "These are Elara's," Mira said, her voice awed, and I realized our mother had armed this resistance, her legacy a fire that burned still.
But as we planned, Vespera's forces attacked, portals tearing open, spitting Peacekeepers and demons—Drevaks, Raveners, and a new horror, Moloch demons, their molten bodies radiating heat. The bunker became a battlefield, Katniss's arrows flying, Johanna's axe slashing, Peeta's strength a bulwark. I drew Speed, Strength, and Unity, my sword a storm, while Tessa's runes shielded the rebels, and Mira's Clarity rune burned, exposing Vespera's wards.
Vespera appeared, her silver hair a halo, her red runes a storm. "The Binding Rune is mine," she said, her voice a hiss, and a wave of dark energy knocked me back, the orb rolling from my pack. Mira dove for it, her Clarity rune flaring, and a burst of light shattered Vespera's spell, giving me time to draw the Return rune.
The orb flared, the rune's spiral glowing, and a portal opened, its edges radiant, showing Idris's war-torn streets. But Vespera's magic surged, a red rune pinning the rebels, and Asmodeus's voice echoed, a taunt. "You cannot escape me," he said, and a Moloch demon lunged, its heat searing my skin.
Katniss's arrow struck, the demon falling, and I drew Severance, its glow a storm, cutting through Vespera's wards. The portal stabilized, but Vespera retreated, her scream a vow of vengeance, and the bunker held, the rebels cheering, their fire unbroken.
We crossed into Idris, the portal closing, the orb's light dimming. The Institute was a fortress under siege, demons flooding the streets, Magnus and Catarina's magic a fading beacon. Maryse rallied the Shadowhunters, her whip a storm, while Alec, Jace, and Clary fought, their blades glowing. Kyle was in the cells, his possession weakening, his Resilience rune glowing, a spark of hope.
Tessa revealed Elara's final plan—a ritual, using the orb and the Return rune, to banish Asmodeus. "It requires your blood, Lilia," she said, "and Mira's. Together, you can seal his realm, but it'll bind you to the rune forever, or cost your life."
Mira's hand found mine, her Clarity rune glowing. "I'm with you," she said, and I nodded, my heart heavy but resolute.
We fought to the council chamber, demons falling to our blades, the orb's light a guide. Kyle joined us, his possession broken, his Resilience rune a shield, and his arms around me were a home I'd feared lost. "You came back," he whispered, his scar warm against mine.
The ritual began, the orb flaring, our blood mixing, the Return rune glowing. Asmodeus's true form emerged, a colossus of flame and shadow, his voice a storm. "You cannot banish me," he said, but Mira's Clarity rune burned, exposing his weakness, and my Unity rune surged, amplifying the ritual.
The chamber shook, portals sealing, Asmodeus's form dissolving, but the rune's cost surged, and I screamed, my vision fading. Kyle's hand held mine, Mira's voice a lifeline, and the Shadow World stabilized, Asmodeus banished, but the pendant's burn lingered, a whisper of his return.
