The portal mages kept building, their hands steady despite the chaos. They followed my directions and Elio’s truth, working together.
Almost there, I said, watching the lattice near completion. Final boundary edge. North quadrant—connect to south anchor. Make it seamless.
The portals snapped into place.
The master changed tactics.
Instead of fighting the lattice, he tried to flow through it, using his own presence as a signal. He attempted to cross the boundary before it fully formed, like water finding cracks in a dam.
I saw it through my portal sense, saw the dimensional stress building as his consciousness tried to exploit the incomplete architecture.
He’s attempting a boundary breach, I reported. Portal mages, reinforce the north edge. Add redundancy.
They moved immediately, additional portals layering over the vulnerable section and weaving reinforcement into the structure.
But the master was already committed to his attack. His presence hit the reinforced boundary, and I saw the opening. Active interference wasn’t a threat. It was a signal I could route.
Elio, expose his dimensional signature, I said quickly. Show us exactly where he’s pressing.
Elio’s truth magic flared. The master’s consciousness became visible—not as corruption but as dimensional distortion, a knot in space itself. It was the shape of something that shouldn’t exist, pressing against reality.
I adjusted my specifications on the fly, pulled up the modification on my tablet, and called it out to the portal mages.
Add a trap condition. Any active interference collapses into quarantine. Build it into the boundary itself.
The portal mages executed, building the trap even as the master pressed against it, like weaving a net around something already caught.
His presence hit the modified boundary and folded, not destroyed or imprisoned through force. Just… contained in a space with no outbound edges.
For three seconds, the lattice held. Then reality screamed.
The structure we’d built—perfect in theory, tested in simulation—encountered something my mathematics hadn’t accounted for:
The master was too old, too saturated with centuries of stolen life force. His consciousness didn’t compress into quarantine cleanly. It bled corruption at the edges like an overfilled container, like trying to catch an ocean in a sieve.
And that bleeding corruption was touching the boundary membrane we’d designed to drain everything it contacted.
The system was trying to drain something functionally infinite.
Keane… Elio’s voice held warning. His truth overlay showed the problem in sharp relief, corruption leaking through the quarantine like water through cracks. The containment is leaking. Corruption’s bleeding through faster than the drain can process it.
Through my portal sense, I watched the lattice strain. The termination rules functioned exactly as designed, draining corruption while enforcing natural endings.
But they were designed for a system, for automated propagation, and for corruption with finite charge. Not for the master himself. Not for a consciousness that had spent three centuries becoming a reservoir of death magic so deep it might as well be bottomless.
The boundary held but barely. Energy bled through the edges. The drain worked but became overwhelmed, like trying to empty a swimming pool with a drinking straw.
How long will it hold? Cyrus demanded from his position at the perimeter. Fire intensified, ready to contain any spillover.
I ran the calculations, feeling the dimensional stress building like pressure behind a dam.
Twenty minutes, I said. Maybe thirty. Then the lattice destabilizes and the quarantine ruptures.
Can you reinforce it? Marigold asked, still kneeling at the convergence point.
Not without fundamentally redesigning the architecture. The math works for draining corruption. It doesn’t work for draining an infinite source while also containing it.
The portal mages held their positions, maintaining the lattice structure, but I could see their exhaustion. I could feel the dimensional strain through my connection to their work.
