First, her right foot drags half a finger’s length through dust before correcting. Then her injured arm tightens against her ribs. Then her breath changes, not louder, only shallower, as if she can cut pain into smaller pieces if she refuses to spend air on it. But she does not ask to stop.
The old passage runs west and upward by degrees, following cut channels that hum faintly beneath the wrong rhythm’s memory. Waiting. The stone around us is old Tajss work beneath zemlja pressure, smooth curves broken by straight grooves, a natural wound stitched with ancient intent.
Sera reads the route in silence. I read her. Neither terrain improves.
The sample pouch rests against my chest, blue pulse faint beneath leather and mineral cloth. The gray thread from her wound is wrapped separately. I keep them apart. I keep both away from her blood. I keep my senses split between passage,pressure, pulse, breath, heat, and the small hitch in her stride she thinks I have not noticed.
No. She knows I noticed. That is why she is angry. But anger keeps her upright, for a while.
A low hollow opens ahead where the passage breaks beneath a collapsed rib of cut stone. Not a room, but perhaps shelter by City standards. The floor is dark, dense, and old enough to carry little vibration. The ceiling curves low. Two walls are natural pressure-smoothed stone, the third old cut blocks fused into the earth. A crack high in the back breathes cool mineral air.
This is a low-vibration pocket. Good for now.
“We stop here,” I say.
Sera does not look at me. “Do we?”
“Yes.”
“I thought we were heading toward the City.”
“We are.”
“Strange. This looks like stopping.”
“It is.”
She turns then, too fast for her balance, too slow for her pride. “We don’t have time.”
“We have less time if you fall.”
“I’m not falling.”
“You are preparing to.”
Her eyes narrow. “That’s an accusation with architecture.”
“It is a fact with patience.”
“I hate when your facts have personalities.”
“I know.”
Her mouth almost moves. Then pain takes the almost away. That decides it.
I step into the hollow first and test the floor. Dense stone. Dry dust. No gray threads visible. No black channels in the immediate wall. No scentless residue. Faint old zemlja leavings farther below, but not close. Deep pressure distant. Natural.
The wrong rhythm is absent. Not gone, only absent. I dislike the difference.
“Here,” I say.
Sera studies the hollow, then me. “Low vibration?”
“Yes.”
“Air?”
“Enough.”
