"It's not the fog itself that reacts," Shyam said, pointer hovering over a waveform on the briefing screen, Dr. Sen and Ishita both leaning in beside him. "It's what's inside the fog reacting to us. I pulled the audio from everyone's comms last night and mapped it against the thickening patterns Ishita logged. Every spike lines up with a vocal transmission — someone calling a position, someone shouting a name. Ambient noise, footsteps, even the vehicle engines barely register."
"So it's listening for language," Sen said slowly. "Not sound in general. Voices."
"Or something close to it. Complex, structured noise. Which means—"
"Which means we go back in silent," Ishita finished, something sharp and satisfied crossing her face. "Hand signals only. No comms chatter unless it's an emergency."
Rathore, arms crossed at the back of the room, nodded once. "Then that's the plan. We move as one unit this time, not scattered pairs. Farah and Nasreen lead visual. Everyone else holds formation on hand signals. Raj, Ishita — you two stay central, close enough to read the fog's behavior without becoming its next experiment."
The Yamuna at midnight looked exactly as it had two nights before, and this time the fog came in exactly as it had before too — fast, localized, wrong — except this time Team 7 met it with silence instead of shouted position checks, and the difference showed almost immediately.
The mist stayed thin. Manageable. Farah's raised hand kept the line moving forward in careful, coordinated steps, no voices at all beyond the occasional necessary whisper, and for nearly twenty minutes the plan worked exactly as Shyam had hoped it would — the fog drifting past them at ankle height instead of swallowing them whole, the creature, wherever it was, apparently uninterested in a target that refused to give it anything to listen to.
Then Dev, near the front of the formation, stopped dead and raised a closed fist.
Everyone froze. Farah crept forward to join him, and Shyam, watching from the center of the formation, saw her expression shift from caution into something colder.
There was a camp. Small, deliberately hidden among the reeds close to the water — a folded tarp, empty ration wrappers, coils of rope, and a single, half-submerged metal cage large enough to hold something considerably bigger than a person.
Nasreen crouched beside the cage, running a careful hand along its bars. "This is designed for aquatic containment. Someone's been trying to capture it. Recently — the mud inside is still wet."
"Zaid's people," Farah said quietly, though it wasn't really a question.
Dev knelt near the tarp, examining something half-buried in the mud beside it — a slim data device, cracked, waterlogged, but not entirely destroyed. He turned it over carefully, and even in the poor light, Shyam recognized the casing immediately: matte black, the same unreadable cuneiform-style scratch marking its surface that had first led them into this entire mess weeks ago.
"Same signature as the terminal card," Shyam breathed. "Confirmed. This is his."
For a moment, nobody spoke, the significance of it settling over the team in the mist-thick quiet.
"He's not just aware of this UMA," Rathore said, low, urgent. "He's actively trying to harvest it. Which means—"
The fog surged.
It happened all at once, without the slow, deliberate build Shyam had catalogued two nights ago — the mist thickening violently around the entire formation in a single heartbeat, visibility collapsing to almost nothing, and somewhere close, far too close, something enormous moved through the water with a speed that displaced enough of it to send a wave slapping hard against the bank.
"It's provoked," Ishita called, voice cutting through the sudden chaos, all careful silence abandoned now that stealth had clearly stopped mattering. "Someone's been hurting it, trying to cage it — it's not hunting us for curiosity anymore, it thinks we're the ones who did this!"
"Formation, fall back to the vehicles, now!" Rathore's voice cracked through the fog like a whip, and the careful, silent coordination of the last twenty minutes dissolved into something far more urgent — bodies moving fast through mist that clawed and swirled and seemed, for the first time all night, genuinely furious.
Something broke the surface behind them — not the slow, deliberate reveal from two nights ago, but a violent, thrashing motion, water sheeting off scales in a wide arc, a sound like a foghorn dragged through gravel tearing across the riverbank loud enough that Shyam felt it in his chest.
"Go, go, go—" Farah's hand closed around Nasreen's arm, hauling her back from the water's edge as a shape — still frustratingly indistinct, still refusing to resolve into anything Shyam could properly measure — surged toward the space they'd occupied a half-second earlier.
The retreat that followed was nothing like the careful, silent formation of twenty minutes earlier. It was raw, fast, and entirely dependent on every combatant doing what they did best in the same three seconds.
Anya was airborne before anyone else had cleared the reeds, wings cutting low and hard through the fog, scooping first Nasreen and then Farah bodily off their feet as she passed — both women too slow on the ground for what the moment demanded, cursed weapons useless against a threat this fast, and neither of them wasted breath objecting to being carried. Dev simply came apart at the shoulders, his whole body dissolving into a churning mass of worms that flowed low and impossibly fast through the mud, reforming whole again only once he'd cleared the tree line. Ishita didn't run at all — she drove her hand into the shallows and rode a surging column of her own summoned water straight up the bank, controlled and precise even at full panic speed.
Shyam tried to do the same thing and immediately discovered how far he still had to go.
The dolphin answered his call fast enough, curling up out of the mud beside him in a rush of shaped water, but the moment he tried to actually ride it, his grip slipped, his balance failed, and he ended up half-dragged, half-thrown across the mud instead of carried, falling steadily behind the rest of the retreating team while the fog behind him churned with something huge and getting closer.
"Raj!" Anya's voice, sharp with real fear, cutting through the chaos from somewhere above.
Then a hand closed around his collar that shouldn't have been visible at all — Rathore, scales flickering faintly at the very edges of her outline, having doubled back invisible and fast enough to close the gap in a way nothing else on that riverbank could have managed. She hauled him bodily off the ground with a strength that felt entirely disproportionate to her size and threw him, without ceremony or warning, directly into the air toward Anya's outstretched arms.
Anya caught him mid-fall, wings straining hard against the sudden weight, and didn't let go again until the vehicles were finally, blessedly in sight.
They made it to the vehicles in a ragged, breathless scramble, the fog releasing them at the tree line as abruptly as it had swallowed them, and Rathore didn't call the retreat complete until every single person had been accounted for twice.
"Report," she said, chest heaving, once the vehicles' doors were sealed and the Yamuna's dark water had gone still and unreadable behind them once more.
"Confirmed hostile intent, tonight specifically," Ishita said. "It wasn't like this two nights ago. Someone's actively hurting it, Captain. That cage wasn't decorative."
"And it's Zaid's operation," Farah added, holding up the cracked, waterlogged device for Rathore to see. "Confirmed by the casing signature. He's not just interested in this UMA from a distance. He's here. Or his people are."
Rathore stared out at the black water for a long moment, jaw tight, something calculating and grim moving behind her eyes.
"Then this isn't a training mission anymore," she said finally. "This is the case. Right here, right now, on this riverbank." She looked around at the whole team — soaked, shaken, alive — before her gaze settled last on Shyam. "We don't just need to contain that creature anymore, Raj. We need to catch whoever's been trying to weaponize it before we do."
Behind them, faint and distant across the water, something enormous surfaced once more, watched the retreating lights of Team 7's vehicles for a long, silent moment, and slipped back beneath the Yamuna's black surface without a single sound.
