Kerris
Iwas bait.
I understood it while studying the Keep's defensive layout, tracing the lines of approach the ferals might use. My scent had drawn them here. My pregnancy had intensified that draw. Every feral massing at Bruk's boundary was here because of me.
"This is my fault," I said.
Bruk looked up from the reinforcement he was carving. "No."
"My scent..."
"Your scent is a consequence of biology. Of the tonic. Of choices neither of us made." He set down his tools and crossed to me. "The ferals are here because they're broken. Because they never learned to build, to wait, to offer something worth staying for. That's not your fault."
"But if I weren't here..."
"Then they'd still be ferals. They'd still be hunting females. They'd still be too damaged to do anything but take." His hand cupped my face. "You being here doesn't create the threat. It exposes what was already true."
I leaned into his touch. Let myself believe him for a moment.
Then I went back to work.
The Keep's structure was both weapon and weakness.
Bruk had built it for permanence, not defense.
The walls were thick, the foundations deep, but there were multiple entry points.
The main entrance. The secondary entrance where we'd installed the pit trap.
The ventilation channels I'd helped redesign.
A dozen small gaps and crevices that a determined attacker might exploit.
I spent two days mapping every vulnerability. Every potential breach point. Every angle of approach.
Then I started designing the system.
"Not traps," I explained to Bruk, sketching in the bone dust. "A network. Each defensive measure connects to the others. The ferals don't just face individual obstacles. They face a system designed to funnel them into killing grounds."
I drew the approach paths. The chokepoints. The places where attacking ferals would naturally cluster.
"Here." I pointed to the main entrance. "This is where they'll concentrate their assault. It's the most obvious entry point, the widest approach. They'll expect it to be defended, but they'll try it anyway because ferals don't plan ahead."
"What do you propose?"
"We let them in."
He went still. "Explain."
"The main entrance opens into the first chamber, the one you use for storage. It's a dead end. One way in, same way out." I traced the layout. "We make the entrance look weak. Inviting. They pour in, expecting to overwhelm us."
"And then?"
"Then we collapse the ceiling."
I showed him the stress points I'd identified. The sections of the overhead structure that were already weak. The places where a few strategic strikes would bring down tons of ancient bone onto whatever was beneath.
"The storage chamber becomes a killing floor," I said. "They come in expecting easy prey. They find a tomb instead."
Bruk studied my design. His expression was unreadable.
"You would destroy part of my Keep."
"I would sacrifice one chamber to save the rest." I met his eyes. "Structures can be rebuilt. You taught me that. But if the ferals get through, if they reach me and the offspring..."
"They won't."
"They might. There are twelve of them. Maybe more by the time they attack." I put my hand on his arm. "I'm not willing to risk our future on 'maybe.' Are you?"
He looked at my hand. At my belly, where our offspring grew. At the design I'd sketched in the dust.
"What do you need?" he said.
We worked through the night.
The storage chamber ceiling wasn't naturally weak enough for my purposes. We had to create the vulnerability. Carving strategic channels into the support structure, weakening load-bearing joints, setting up the collapse without triggering it prematurely.
It was delicate work. One wrong cut and we'd bring the whole thing down on ourselves. Bruk carved while I directed, my calculations adjusting in real-time as we discovered the actual composition of the bone overhead.
"Here," I said, pointing to a junction point. "Remove material from this side. About two inches."
"That will compromise the entire western support."
"That's the idea. When we trigger the collapse, the western side falls first. It creates a cascade effect. One failure leads to the next until the whole ceiling comes down."
He made the cut. I held my breath until I confirmed the ceiling was still stable. Barely. One good impact and it would all come crashing down.
"Now the trigger mechanism," I said. "We need something I can activate from a distance. Something that will start the cascade."
"I can do it manually. Strike the weak point when..."
"No." The word came out sharper than I intended. "You won't be in that chamber when it collapses. I won't risk losing you to save the Keep."
"Kerris..."
"I've already lost everyone who was supposed to care about me. My family chose my brother over me. My parents chose to pretend I didn't exist." I grabbed his arm, forced him to look at me. "I'm not losing you too. We find a way to trigger this remotely, or we don't do it at all."
His expression changed. The same look he'd had when I first said I wanted to stay. Wonder. Recognition.
"There's a way," he said. "Bone resonance. A strike at the right frequency can travel through connected structures. If I position myself at the entrance to the second chamber..."
"You can trigger the collapse without being inside."
"Yes."
I kissed him. Hard. Desperate. Grateful.
"Then that's what we do."
By dawn, the trap was ready.
The storage chamber ceiling was a disaster waiting to happen. The main entrance looked weakened, inviting. Bait for ferals too damaged to recognize the danger. And Bruk had identified the resonance point where a single strike would bring it all crashing down.
I stood at the entrance to the main chamber and looked at what we'd built. Not just a trap. A system. A defensive network designed by a structural engineer and implemented by a builder who'd spent twenty cycles mastering his craft.
"They'll come tonight," Bruk said. "Or tomorrow. The gathering is almost complete. Fifteen of them now."
Fifteen. More than we'd planned for. The ceiling collapse might kill five, maybe six. The other traps another three or four. That still left at least five ferals that Bruk would have to fight directly.
"Can you take five?" I asked.
"I can take five." His voice was certain. "Especially if they're already damaged. Panicked. Confused."
"The collapse will disorient them. The dust, the noise, the loss of their pack members. They won't be thinking clearly."
"They don't think clearly now. After the collapse, they'll be animals. Easy to pick off."
I wanted to believe him and trust that we'd planned for every contingency, that the system would work, that we'd survive this attack and raise our offspring in the Keep he'd built.
But I was an engineer. I knew that systems failed. That calculations had margins of error. That even the best designs couldn't account for every variable.
"If something goes wrong," I said. "If they break through..."
"They won't."
"But if they do." I grabbed his hand, pressed it against my belly. "Promise me you'll get the offspring out. Promise me you'll protect what we've built, even if..."
"Nothing is going to happen to you." His voice was fierce. Final. "I've waited twenty cycles for you. I'm not losing you to ferals. Not tonight. Not ever."
He pulled me against him. Held me while the sun rose over the Ossuary, painting the bone formations in shades of gold and pink.
"We survive this," he said. "We protect our offspring. We build a future. Together."
I let myself believe him.
What else could I do?
The ferals were coming. Our traps were set. And somewhere deep inside me, our offspring was growing, unaware of the violence about to unfold around it.
I rested my hand on my belly and made a silent promise.
Whatever it took. Whatever I had to sacrifice. I would protect this future.
