Lava rivers snaked down Merapi's flanks, turning the air into a hellish furnace. Arief shielded his eyes from ash clouds as academy survivors rallied at the crevice mouth. "Evacuate to Bali coords or hold?" Kairo barked, clutching a bandaged arm, his blindfold singed.
Lira scanned scry-orb feeds: Eclipse drones seeding the volcano's core with shard amplifiers. "Shatterer's triggering mega-eruption. Thousands die if it blows."
Arief's jaw set. "We stop it. Heroes don't run." Echo bond with Lira thrummed agreement; Raka screeched assent.
Kairo nodded grimly. "Caldera dive. I'll seal surface rifts. Go—Throne Key purifies shard corruption."
The trio plunged into the volcano's throat via echo-glide: Arief's shadow-wings carrying them down steaming vents. Heat warped vision; pumice rained like fiery hail. "Like diving into a dragon's gut," Arief quipped, sweat evaporating instantly.
Deeper, shard drones swarmed—compact killers with buzzsaw rotors. Raka shredded lead waves; Lira's calon arang illusions tricked them into self-colliding. Arief's naga chains netted clusters, smashing against walls.
They breached the magma chamber: a cavernous hellscape of bubbling pools, crisscrossed by Eclipse rig—massive crystal amplifiers pulsing red, overloading the earth's echo veins. At center: a shard titan, twice a rift lord's size, guarding the core detonator.
"Intruders!" it bellowed, seismic stomps cracking floors. "Shatterer’s dawn breaks!"
Battle frenzy: Titan swung magma-forged fists; Arief dodged, shadow-porting atop its shoulder, keris carving runes. Chips flew, but regen shards healed it. Lira summoned phantom legion, harrying joints; Raka clawed eyes.
"Flank the amps!" Arief yelled. They split: Lira/Raka dismantling rigs—her staff shattering crystals, his talons ripping conduits. Explosions rocked the chamber, red light dimming.
Titan roared, grabbing Arief in vise-grip. Ribs creaked; idol burned hot. Visions flashed—Airlangga's era, throne forged in this caldera to bind echoes. "Purify!" Arief channeled Throne Key fully—golden light erupted, naga evolving into imperial dragon form.
He burst free, dragon jaws clamping titan neck, purifying shards to harmless dust. Lira sealed with vortex; Raka finished with talon plunge. Titan crumbled, detonator sparking out.
Victory short-lived—chamber destabilized. "Collapse incoming!" Lira shouted. They rocketed upward via fused wings, outpacing lava surge. Bursting surface-side, Merapi belched smoke but stabilized—no apocalypse.
Cheers from Kairo's forces. Casualties low; academy saved. Kairo clasped Arief's shoulder. "You wield the throne's true fire. Bali next—strike Nexus heart."
Post-battle glow: around healing fires, stories swapped. Lira leaned into Arief. "Dragon mode? Swoon-worthy." He flushed; their first kiss sparked—echo-lit, passionate amid cheers.
New ally emerged: Miko, sly hacker-kid with pocong echo (ghost teleport). Ex-Nexus intern, defected after Jax recruited him briefly. "Got lab blueprints. Traps galore, but backdoor via Ubud rice fields."
Jax intel? Arief tensed. "Traitor scum."
Miko shrugged. "Brainwashed first. Shatterer mind-shards everyone."
Kairo unveiled map: Bali Nexus under volcano-masked fortress, guarding "Eclipse Crown"—artifact to force realm merge. "Infiltrate, destroy crown. Prophecy demands it."
As night fell, garuda fleet prepped for exodus. Arief stared at stars, idol warm. Father’s voice echoed in dreams: Bloodline's burden, son's glory.
Sudden quake—not Merapi. Scry-orb flared: Bali skies rift-torn, Shatterer’s voice booming globally via hacked broadcasts. "Echo heir delays the inevitable. Nexus rises—join or perish."
Arief clenched fist. "Bali blitz. Endgame starts now."
Fleet launched under moon, wings blotting stars. But horizon glowed unnaturally—Nexus defenses awakening early.
