Silas handed the spike to Ren. "I need you to distribute these. Not to everyone. Only to the ones who didn't join the chanting. Find the ones who are still looking at the ceiling. Find the ones who are afraid."Ren took the spike. "What do I tell them?""Tell them the 'Dead-Drop' drill is no longer a game," Silas said. "Tell them to aim for the Axillary Vent. If they see a guard, they don't run. They drop."Silas reached into the second bag and pulled out a cache of small, glass vials. They were filled with the "Acid Breath" catalyst he had used on the vault door."These are for the Caretakers," Silas said. "If the metal crabs come, break one of these on their sensors. It won't kill them, but it will blind them. It will give the Dregs a chance to get close."Ren looked at the weapons. He looked at Silas’s silver-lattice skin. "You're leaving, aren't you?" Ren asked."The Spire is calling," Silas said.He stood up. He felt the vibration of the building changing. The "Haze" was no longe

The wind on the rooftop of the Valhalla Academy did not blow; it screamed. It was a cold, sharp wind that carried the smell of the coming storm. Far below, the clouds were a thick blanket of grey and purple, hiding the Sump from the eyes of the High Command. Silas Kapito stood at the very edge of the roof. His toes were inches away from a five-mile drop. He did not look down. He was looking out.Above him, the "Inquisitor Drones" were dancing. They were beautiful and terrifying. Unlike the heavy, clunky Sentry-Bots of the lower levels, these machines were slender. They were made of a dark, matte-black alloy that seemed to drink the light. They had six long, needle-like legs that moved with the grace of a spider walking on water. Instead of loud engines, they had silent "Aether-Drives" that made a low, hypnotic hum. Their red sensor eyes pulsed in the dark. Blink. Blink. Blink.They were searching. They were hunting for a specific heat signature. They were looking for the "Iron-Gre

The medical wing of Valhalla Academy was a forest of white curtains and cold glass. Usually, the lights were bright and the air was full of the quiet hum of healing machines. But tonight, the power was low. The "Blackout" had turned the wing into a world of long, jagged shadows.Elara sat at a small desk in the corner. She was surrounded by glowing screens that showed the heartbeats of her few remaining patients. Her face was pale, and her eyes were red from a week of no sleep. She was a healer in a school that only wanted to produce killers.The heavy steel door at the end of the hallway groaned. Clink. Clink. Clink.Elara didn't need to look up to know who it was. She knew that sound. It was the sound of Silas Kapito’s footsteps—steps that were too heavy for a boy his size. Every time his feet hit the floor, the metal tiles gave a tiny, sharp cry.Silas walked out of the shadows. He was stripped to the waist. His skin was the color of a rainy sky, and the silver-lattice marrow in his

The "Iron Crucible" was a room that did not want anyone to stay. It was a small, round chamber hidden deep inside the cooling vents of Sector D. The walls were made of heavy iron plates that were always wet with a strange, oily sweat. It smelled like a hospital that had been built inside a junk yard, copper, sharp chemicals, and the dusty scent of old machines.Silas Kapito sat on a low metal stool in the center of the room. He was naked from the waist up. His skin was very pale, but it looked different now. It had a dull, grey shimmer, like the surface of a cloud. This was the "Iron-Grey" hue, the sign that his bones were no longer made of soft calcium. They were a lattice of silver and stone.His sister, Elara, stood behind him. She was holding a small, silver tray. On the tray were the tools of a nightmare: a micro-laser scalpel that glowed with a tiny blue light, and a specialized conductive probe that looked like a long, thin needle made of glass."Silas," Elara whispered. Her

The room Silas called the Iron Crucible was no longer just a room. It was a tomb for the boy he used to be.The air was frozen, but Silas Kapito did not feel the cold. The lights were flickering with a dying orange glow, but he did not feel the heat. He sat on the floor, his back against a massive water pipe. His skin was the color of a rainy morning, a pale, ghost-like grey. But it was the silence that was the loudest thing in the room.Inside his head, the noise was gone. The constant "background music" of being human, the itch of a shirt, the throb of a healing bruise, the tiny stings of cold air, had been erased. Elara had done her job well. She had stripped his nerves. She had closed the gates of pain.Silas looked at his hands. They felt heavy, like two blocks of stone. He could move them perfectly. He could tap his fingers against the floor. But there was no feeling of "touch." He knew he was touching the floor because he could see his fingers move. He could hear the click of
