Chapter 7: The Vacuum Bolt
"Valerius! Get Elara to the induction vent!" Kaelen shouted, his voice straining against the roar of the cracking star-cradle. "If the star goes, the vent is the only place with reinforced shielding!"
"What are you doing?" the Mage cried, dragging Elara's limp form toward the heavy lead-lined alcove.
"I'm changing the oil!"
Kaelen lunged. Not at the Exile, but at the primary pneumatic line. The Exile flicked a wrist, and a shard of ice sliced through Kaelen's shoulder. Blood, hot and red, sprayed onto the glass bridge, but Kaelen didn't flinch. He slammed his wrench into the brass coupling of the main pressure line.
The coupling didn't budge. It was fused by centuries of heat-scaling.
"Inelegant," the Exile hissed, raising both hands. The air around Kaelen began to crystallize into a cage of jagged spears. "You die for a city that calls you 'Dullard.' You die for a king who wouldn't let you breathe his air. Why?"
"Because my sister is in that city," Kaelen gritted his teeth, his muscles bulging as he threw his entire weight against the wrench. "And I'm the only one who knows how to fix the leak!"
With a scream of protesting metal, the coupling snapped.
A jet of high-pressure, superheated ether-gas erupted. Kaelen didn't turn away; he used the force of the escaping gas to propel himself across the bridge, sliding under the Exile's icy cage.
He reached the base of the counterweight's pneumatic piston. He pulled the last ether-canister from his belt—the one he had modified with a reverse-intake valve. He jammed it into the broken line.
The effect was instantaneous. The canister acted as a vacuum-sink, sucking the pressure out of the piston. The massive obsidian counterweight, deprived of its pneumatic cushion, dropped like a fallen moon.
THOOM.
The weight slammed into the primary gear-train. The entire room shuddered. The gears, encrusted with Frost-Blight, shrieked as the sheer physical force of the falling obsidian crushed the violet ice into powder.
The "Petals"—the mile-wide bronze mirrors—began to groan and rotate. They turned away from the dark earth and aligned themselves with the vertical thermal-shafts leading to the city.
The Exile let out a sound of pure agony. The sudden refocusing of the star's radiation created a "Flash-Heat" in the chamber. The violet ice on the walls began to boil away. The Exile's translucent body started to steam, his frozen features melting into a formless grey slush.
"No!" the chime was now a distorted, dying wail. "The cold... the peace... it was almost here!"
"Go find it somewhere else," Kaelen gasped, collapsing to his knees as the room turned from a freezer into a furnace.
The miniature star at the center of the room began to stabilize. The cracks in the containment glass, heated by the sudden surge of pressure, began to "self-weld," the glass flowing like honey until the sphere was whole again.
A pillar of pure, golden light shot upward from the mirrors, roaring through the central shaft of Aethelgard.
Above them, Kaelen knew, the frost-vines in the streets were disintegrating. The frozen workers in the doorways were being bathed in the first real warmth they had felt in weeks. The "Aethel-Tone" was no longer a scream; it was a steady, low hum—the heartbeat of a city brought back from the dead.
Kaelen crawled toward the induction vent. His skin was blistered, his clothes were scorched, and his shoulder was a numb mess of blood and ice.
"Elara?" he croaked.
Valerius was hunched over her. The Mage's hands were no longer grey; they were flushed with a faint pink. The ambient heat of the restored Core was acting like a transfusion.
Elara's eyes fluttered open. The gold was gone, replaced by her natural, warm orange Spark. She looked at the glowing star-cradle, then at her brother.
"You fixed it," she whispered, a small, shaky smile touching her lips.
"It was just a clogged pipe, El," Kaelen said, his head spinning as the adrenaline began to fade. "Always is."
But as the golden light filled the chamber, Valerius stood up, looking not at the star, but at the shadows where the Exile had vanished. "Kaelen... the Exile. He was just a scout. If they can reach the Core once, they can reach it again. And the star... it's smaller than it was yesterday."
Kaelen looked at the miniature sun. It was indeed smaller—a flickering ember in a vast, dark universe.
"Then we better start building a bigger wrench," Kaelen said.
