The passage is narrow — single-file, low ceiling, the kind of infrastructure corridor that exists in every old building and that most people forget about.
My shadows scout ahead through absolute darkness, mapping the path to the laboratory from below while tracking the strike team’s movement through the corridors above.
They’re faster than I expected.
By the time I reach the laboratory’s tunnel access, the team is already in the corridor outside the main door. I can hear them through the stone — boots, the particular metallic sound of weapon safeties disengaging, a voice speaking in the clipped cadence of operational communication.
I have forty seconds.
My shadows flood the laboratory through the tunnel entrance.
Not entering physically — extending through the crack beneath the access panel with the fluid precision the blood circle bond has amplified.
Thirty shadow tendrils fan across the room simultaneously, each one targeting a specific piece of evidence.
The monitoring crystal. The residual energy patterns on the stone bench. The fire-crystal calibration equipment Constantine left from our last session. The containment circle’s salt traces from the blood ritual.
The monitoring crystal is the priority.
I wrap it in shadow density thick enough to dampen its output, then pour Command influence through the construct — not targeting a person this time but the recording medium itself, overwriting stored data with fabricated session logs that show standard supplemental instruction.
Shadow manipulation exercises. Elemental theory discussion. The kind of boring, documented-compliant content that matches what the crystal was supposed to be recording.
Twenty seconds.
The fire-crystal equipment goes next. My shadows disassemble Constantine’s calibration setup and redistribute the components to positions consistent with standard classroom demonstration.
The salt traces from the containment circle get scattered — broken pattern, unrecognizable as ceremonial configuration, just mineral residue from geological samples that any academy laboratory might contain.
Ten seconds.
The residual energy signatures are harder. Fire-shadow integration leaves traces that persist in stone for weeks — thespecific frequency of sustained intimate magical contact that no amount of physical rearrangement can disguise.
I layer concealment over the signatures — shadow density that absorbs the readings, returning null values to any detection equipment that scans the walls.
The door opens.
I pull my shadows back through the tunnel access as the strike team enters the laboratory.
From my position below, I can monitor their movements through the sentinel constructs I left embedded in the room’s shadow infrastructure — passive observation nodes that look like natural darkness and report with the precision of surveillance equipment.
Four operatives. Systematic search pattern. Detection equipment activating with the particular hum of military-grade scanning.
They check the monitoring crystal first — playing back the fabricated session logs, comparing timestamps to the room assignment schedule, finding exactly the boring supplemental instruction records that my Command wrote over the real data.
“Room’s clean,” the team lead reports through a communication crystal. “Monitoring records show standard instruction sessions. No anomalous energy signatures detected.”
The concealment is holding.
My layered shadow density absorbs their scanner readings and returns the null values I programmed.
But the team doesn’t leave.
They expand their search — checking walls, scanning the floor, running detection protocols I don’t recognize through equipment that operates at frequencies my concealment wasn’t calibrated for.
One operative pauses near the stone bench.
The bench where Constantine kissed me. Where his fire essence saturated the surface during our first integration. Where the molecular structure of the stone itself changed to accommodate the sustained thermal contact of a fire practitioner’s hands gripping the edge while his mouth —
