The world went quiet after the Behemoth left. Too quiet. My ears still rang from its roars. We stood on the glassy plain, three small figures catching our breath. Not from running anymore, but from pure shock.
I couldn't stop staring at the mountains in the south. A city. A real city outside the Wall. My mind struggled to accept it. Everything I'd been taught in Aethel was a lie. The Wall wasn't protection. It was a cage door.
Lyra found her voice first. "They saved us."
Roric kept his hand on his sword. "They attacked the Behemoth. That doesn't make them friends."
"But look what they did!" I said, my eyes still fixed on those strange buildings. "Two shots. They have answers, Roric. Answers my brother died for."
A low humming sound cut through the air. From a hidden canyon, three vehicles emerged. They didn't have wheels - they floated on air, kicking up dust. Their metal bodies were scarred and old-looking. Weapons were mounted on their roofs.
"Get down!" Roric yelled.
But it was too late. The vehicles surrounded us in seconds. They moved with scary precision.
A hatch opened on the lead vehicle. Soldiers climbed out. They wore smooth, dark armor that covered them completely. Their faces were hidden behind tinted visors. They moved together like a single machine.
One soldier stepped forward. A woman's voice came from her helmet. "Drop your gear. The grappling hooks and swords. Now."
Roric stood tall. "Who are you?"
The soldier didn't answer. She made a sharp gesture. Two soldiers moved forward. One touched a weapon to Roric's side. Blue energy crackled. Roric cried out and fell to the ground, his body shaking.
Lyra and I froze, our hands going up.
"We won't ask again," the voice said.
With shaking hands, I unbuckled my gear. It hit the ground with a heavy thud. My swords followed. Lyra did the same beside me.
They searched us quickly, taking everything. Then they tied our hands with strong plastic cords.
"Where are you taking us?" I asked.
The lead soldier looked at me. I could see my scared face reflected in her visor. "To see if you're worth the ammunition we spent."
They pushed us into the back of one floating vehicles. The inside was cold and metal, smelling like lightning. The ride was perfectly smooth, even over the rough ground.
Through a small window, I saw us approach the mountain. A hidden door slid open in the rock. We passed through, and the door closed behind us with a final sound.
We were inside.
The vehicle stopped in a huge cave filled with other craft and soldiers. The air tasted clean and artificial. They marched us through metal hallways with glowing pipes on the walls.
Finally, they put us in a small room with a table and chairs. The door sealed shut behind us.
Roric was awake now, rubbing his jaw. "Savages. They have no honor."
"They have weapons that can kill Behemoths," Lyra said. "I'll take that over honor."
The door opened. The soldier who captured us stood there without her helmet. She was young, with sharp features and short dark hair. Her eyes were gray and cold.
"I am Commander Jax of the Iron Citadel," she said. "You're from Aethel. The walled city."
It wasn't a question.
"How do you know that?" Roric demanded.
Jax ignored him, looking at each of us in turn. Her eyes stayed on me the longest.
"Your equipment is primitive. Your tactics are reckless. Yet you found a primary relay and drew a Class Four sentry. Explain."
This was the moment. Do I tell the truth?
"My brother discovered the truth," I said before Roric could speak. "The Wall is a prison. The Behemoths are guards. We found the relay station. We were looking for the source - the Heart of the system."
Jax's face didn't change, but I saw a flicker in her eyes. "Your brother. Is he here?"
"He's dead," I said, the words still painful. "Killed by an Obsidian Behemoth when it broke our gate."
Jax showed her first real reaction. Her eyebrows went up slightly. "An Obsidian? It breached your wall?"
"It didn't breach it," I said, meeting her stare. "It unmade the gate. It was a key. And we destroyed it."
Silence filled the room. Jax looked at me like I was a puzzle she was trying to solve.
"You destroyed a Key Sentinel," she said finally. "With what?"
"With whatever we had," Roric growled, standing up. "We fight with what we have."
Jax's cool eyes moved to him. "And what you have is barely enough to scratch them." She looked back at me. "Your brother was right. You are prisoners. But you're not the only ones."
She walked to the wall and touched a panel. A map appeared, showing the Scarred Lands. I saw Aethel's wall, our small city inside. But then I saw other marks - other walled cities scattered across the wasteland.
"The Makers didn't just build one prison," Jax said. "They built many. They put humanity in cages to see what would happen. To see how we would evolve."
She zoomed the map in on the mountains around us. "The Iron Citadel isn't a city. It's a resistance. We're what happened when one prison broke free."
My breath caught. "You escaped?"
"Generations ago," Jax said. "We've been fighting ever since. Studying the Behemoths. Learning their patterns. Finding ways to break their systems."
She looked at me, her gaze intense. "That Key Sentinel you destroyed? That was the first time any of the prison cities has ever fought back successfully. Until now, the prisoners have been docile."
Roric sat down heavily. The truth was too big to take in.
"So what happens now?" Lyra asked, her voice small.
Jax's lips formed a thin, hard line. "Now you have a choice. You can go back to your cage. Or you can stay and learn how to fight. Really fight."
She looked straight at me. "Your brother found the first truth. The question is, do you want to learn the rest?"
The room was silent. I thought of Kael. I thought of his journal. I thought of the people in Aethel, living their safe, ignorant lives behind walls that were really bars.
There was no choice to make.
I stood up, my hands still bound. "Tell us everything."
