They walked back in the blue before dawn.
The North Annex path was still damp earth and moss. Broom marks from yesterday's sweeping still showed in the clay near Chawng's gate. A kettle left out from night watch, cold. The gate itself, unlatched, leaning a half-inch. No humming.
Then the stone started.
First a single cut-stone slab where the Annex path met the main service road. Then another. Then paved stone all the way down. Lanterns still burning on iron posts, dew on the glass. The air changed with it. Sound came back. Not wind through pine. Voices. Boots. A bell tower practicing the five o'clock scale two notes flat.
James's eyes dropped to the paving before he stepped onto it, checking where slab met mud.
Drake's stride shortened half a step where the night patrol's weight had dragged on the corner stones.
Xander winced as they passed under the arch by the water tower. Sound stacked between the buildings.
Kara walked past a junior heating post where a first-year had left a standard Warmth Ring running to keep dew off a bench. The ring burned orange and stuttered, throwing heat at damp air.
Her hand twitched. She didn't fix it.
They were still in worn coats. Muddy boots. Grey clay still caked to shins from Sector Four yesterday. The five of them walked in step without needing to talk.
The Central Quad at dawn was already full.
Two hundred slates. Dawn roll call. Line-squads in polished uniforms, Mana rings humming clean and even, spell-lances vertical, boots mirror-shined despite drizzle. Instructors with recording slates. Brass resonance meters on tripods. Bells ringing the hour.
And five slates left empty near the back, where Squad 7 used to stand.
Senior Proctor Vance stood there with his brass erg-tracer case tucked under his arm. The same case from yesterday. Beside him, Squad 3 leader, silver chevrons catching thin sunlight, clipboard tucked, wire wiped down with dry cloth. Valen.
Squad 7 stepped onto their old slates.
Worn coats in a sea of pressed blue. No active rings. No hum. Quiet posture while everyone else held breath for command.
Two rows over, a whisper carried over humming rings.
"Those the Annex five?"
"Invalid log. Cleared a culvert with no ergs."
"Heard they got expelled, then un-expelled."
Valen didn't whisper. He looked sideways at them and kept his face even. Squad 3 around him held clean formation, fast, disciplined. Three months of line drills. Proper procedure.
Vance adjusted his wire-rimmed spectacles. Lenses fogged, then cleared.
"Field recalibration exercise," Vance said. His voice was flat, dry, precise. "Northern ridge. Grid nine through twelve. Joint patrols. You will operate under active surveillance. All inputs to be logged. All matrices to be recorded."
He looked at his slate. Red wax. Sector Four log. Invalid stamp still damp.
"If we cannot validate you here," Vance said, looking at Squad 7, "we will put you somewhere our system understands."
Valen stepped forward half a step.
"Squad 3, paired with Squad 7," Valen said. "Squad 3 will maintain standard formation and logging. Squad 7 will operate as you operated at Sector Four. I will maintain call discipline. Vance will trail with tracer."
Valen's eyes flicked to Drake's muddy shoulder, to Kara's hands tucked in wet sleeves, to James's hands in coat pockets.
"Don't slow us down," Valen said. "Call your movements."
James nodded. "Won't."
They moved out through the north gate. Stone to dirt again. The humming of two hundred Mana rings faded behind them. Ahead, ridge fog, wet pine, the same ridge that had flooded Sector Four.
Squad 3 moved like the manual. Point man with detection ring, flankers with shields half-raised, rear with recording slate active, calling every twenty steps: "Grid nine entry, ergs stable, no anomaly."
Luna's eyes were on the bank, not the detection ring. Drake watched where the squad's weight fell on the soft shoulder. Xander wasn't casting, he was listening to where wind caught between trunks. James kept his hands down.
Ten minutes in, Valen's point man started building a large array. Big, clean, textbook — an Area Scan Lattice, thirty seconds to form, would light up the whole gully in thermal.
Kara looked at the gully. Small slide. Wet leaves. No heat differential. Too wet to read.
She said, quietly:
"Don't."
Valen turned. "Reason?"
"That will blow all the birds," Kara said. "And it's wet. You won't see."
Point man paused, lattice half-formed, humming.
Valen considered it. "Hold scan."
He marked his slate: Visual assessment, no thermal differential.
Two minutes later, the trail narrowed over a root mat. Squad 7, used to reading each other, all stepped to the same side without a word. Old habit from carrying water without spilling.
James gave a short call — "left, step —"
Valen's second stepped right. Right into Drake, who had shifted left expecting the mat to hold.
They tangled. Not a fall. Just a bump, boots in mud, shield ring flaring awkwardly to catch balance.
"Hold!" Valen barked. Squad 3 snapped to hold, shields up.
Drake put a hand up. "My bad."
He stopped. He had thought they'd all feel where weight should go. They didn't.
James looked at the root mat, then at Valen's second. "Sorry. Should have called full."
Valen stared at them. Not angry. The look of someone hearing a dialect that almost sounds like his.
The ridge opened. Grid nine to ten. Wind picked up, carrying cold off upper snow.
Xander lifted his head.
"Draft's cutting left to right up there," he said quietly to Luna. Luna nodded and pointed to a stand of pine where snow had melted faster.
Valen heard it. "If you have a report, call it in standard format."
Xander blinked. "Oh. Cold air drainage off peak, moving north-west through gully. Probably pushes any loose scent down."
Valen logged it: uncategorized observation.
They reached the top of the slope. Below them, six hundred yards down a boggy drainage slope along Western Ridge, was Waypoint 2 — a grey, moss-covered granite marker half-sunk into turned clay and rotting pine needles.
Vance was fifty yards behind. The brass case clicked every four seconds. Still zero.
Valen looked at the marker, then at Squad 7's muddy boots, then at his own kit with brass tripods and copper alignment wires and dry cloths for crystal slates.
"Waypoint 2," Valen said. "We set tripods, realign marker, log channel. Standard survey."
Squad 3 unpacked with rhythmic speed, unspooling copper wires, wiping slates.
Squad 7 stood five paces back in wet needles, caked in morning mud, watching silver chevrons catch thin sunlight.
Valen glanced at them once more, then turned downhill.
"Moving," he called.
Behind him, Drake lifted his boot, checked where Valen had stepped, and followed.
