“We no longer have faith in myths,” he would announce on the Internet, grinning against the heather hills. “They call it algorithms. #MacGregorMythsDebunked.”

His dad, Ewan Alistair, nodded approval at the breakfast table. “Keep questioning, lad. That’s how we stay honest.”

But Grandpa Alistair, from the fireside chair, simply said: “Lights on the moor don’t think about signal bars or battery percentage.”

A few weeks after the drone incident, in that same summer of 2025, Alasdair decided to camp alone on the moor above the glen — seventeen, invincible, testing his new cell phone on a “Highland Glitches” video series. Full moon forecast, mist forecast low over the peat hags: perfect conditions to demonstrate once and for all that will-o’-the-wisps were methane flares or phosphine gas from decaying vegetation.

“Science closes the loop,” he told camera as he packed the tent, tripod, power bank, and emergency foil blanket. “Tonight we are tracking the Dog’s Knowe path. Not fairy tales.”

Dusk came slowly, the sky turning deep indigo. Mist coiled knee-high over bog-cotton; the dry heather became a pale ghost. Into the air rose the scent of wet peat and heather sap, a faint metallic bite of approaching frost. Alasdair walked the usual way, phone sweeping in slow arcs: heather turning bright green at night, black mirrors in the peat pools.

9:17 p.m.: first flicker. A pale, low orb bobbed knee-high, thirty metres to his left — precisely matching great-great-grandad Malcolm’s 1878 notebook description of “corpse-candles on the Black Moss.” He smiled at the camera, zooming in: “Phosphine gas. Classic bog emission. Let’s LiDAR it.” The scanner pinged: empty air. No solid object.

The orb steadied, then split — three lights, strung across a shallow mossy dip like lanterns on a wire. Phone blinking: compass twirling wild, flashlight pulsing chaotic white-blue-white. “EM interference,” he said, steadying his arm. “Expected near bog iron deposits.”

The orbs bobbed above the most lush, greenest heather — classic bog, dangerous sucking ground. But one solitary light hung over dry tufts and denser peat. Malcolm’s faded entry flashed in his mind unbidden: Lights indicate danger and the safe path. Follow the lone candle if ye wish to live.

The phone beeped: GPS recalibrating. The map blanked to grey. Alasdair approached the cluster, testing the theory — just one stride, just enough to justify the video. His right boot sank instantly. The moss top split with a wet tearing noise; black icy water burst up around his ankle, so cold it burned like acid.

He shifted weight to pull free — and the ground gave way entirely. Peat around his calf in the next heartbeat, like a cold viscous tar. Both legs were in now — knee-deep within seconds — and the suction gripped with obscene power. The bog seemed to breathe: thick, oily peat squeezed his legs with slow deliberate pressure, pulling him downward in minute, unbroken increments. Every movement only tightened the grip. Black water rose to mid-thigh, slipping through fabric, numbing the flesh.

His heart pounded so hard that metal tasted in his mouth. Breathing came in short choked gasps that clouded the screen he still clutched in a death-grip. The cold sank into his bones, turning his legs into heavy inert weights. The smell clung to his nostrils — sulphur, decay, the private rot of things dead long ago — and every pull dragged more of that foul black ooze higher.

“Shit — okay, dangerous land confirmed,” he gasped to camera, voice cracking high and thin. “Gas rises there. Reaching back now —”

He attempted to rock backward onto his heels. The moss ripped in wet sucking strips; water surged to his hips. The cold seared. He could feel his own pulse lurching while his fingers fumbled clumsy.

The orbs looked on from ten metres away — passive, pale, unblinking. The lone light brightened once, twice, then drifted a couple of paces to the right, hovering above solid ground. Alasdair lunged toward it, hands windmilling for balance. His fingers gripped heather roots, hard and fibrous, real against his palms. He inched forward, peat sucking away at his legs with wet reluctant smacks. Every pull was like tearing a rope from something that kept pulling back.

At last, he hauled his knees and feet onto firmer turf, rolled sideways, lay on his back gasping, staring at the moon through fog. His legs throbbed with returning circulation — pins-and-needles blowing up into fire. The clustered lights behind him dimmed and faded. New orbs bloomed beside him along a safe line ahead, one by one, forming a row across the moor.

The phone screen flickered: Low Power Mode? Battery read 87%. Impossible drain — ten minutes since full charge. The camera app launched itself, night mode framing the orbs perfectly — dozens now, a slow snake of pale fire curling toward the glen edge.

“Whoa,” he breathed, voice cracking. “Swarm intelligence? Bio-luminescent fungi? Some kind of —”

Phone vibrated hard. Torch cycled red-blue-police-strobe without input. He laughed — nervous, high — trying to keep the camera steady. “Hacked? Or bog radiation frying circuits? This is gold content.”

The path of lights led him to a low rise — the same “island” of firm ground Malcolm had described in 1878. The orbs gathered there, expectant, forming a loose circle above the heather. The phone settled: compass locked north true again, battery inexplicably back to 100%. Then, on the locked screen — no app open — a single message appeared in white text on black: STEP LIGHT.

Alasdair yelped, dropped the phone. It hit peat with a soft thud. He snatched it up — booted fine, no log entry, no trace of the text. The lights swirled once — almost playful — then winked out one by one until the moor lay silent under the moon, only the distant burn murmuring and his own ragged breathing.

He bolted for the glen, mud-caked, heart still racing, phone clutched like a talisman. The footage was crisp: orbs moving coordinated, battery log flat at 100% the entire time.

The family waited at the factor’s house: Ewan grim-faced, Isla smirking but wide-eyed, Grandpa Alistair calm in the armchair by the fire.

“Flares?” Ewan asked quietly. Alasdair shook his head, voice still unsteady, legs trembling with remembered cold. “They followed me. Saved me from the bog. Messed with the phone like… like answering back.”

Alistair tapped the binder on the table. “Malcolm said the same in ‘78. Lights listen. Sometimes they speak.”

Alasdair opened the Google Drive folder on his laptop, fingers trembling slightly. New entry: Moor lights interactive, August 2025. GPS/EM disruption targeted and deliberate. Followed exact family path from 1878 account. Pulled me from sinking bog. Not gas. Not glitch. Sentient? Guiding? He started a TikTok draft: “Algorithms lied. Some code writes itself. #MacGregorMythsRealAF.” He didn’t post.

Next campout — same moor, same moon — he left the phone in the tent. No camera, no LiDAR, no safety net. Just eyes, ears, memory. He walked the Dog’s Knowe path slowly, breath fogging in the cold. The lights came anyway — low, patient, blooming one by one along the safe line. No strobing, no messages. Only quiet guidance across the treacherous ground. He followed.

At the rise they ringed him once — soft, almost kind — then faded. Back at the tent he sat until dawn, watching the stars wheel overhead, the glen breathing slow and ancient beneath him. No footage. No proof. Only the memory of lights that had waited centuries for a MacGregor to finally look up from the screen — and the visceral, bone-deep memory of peat closing around his legs, patient, merciless, and very nearly final.

In the Drive folder he added one last private note, not tagged, not public: Some things don’t need debunking. They just need noticing. Grandpa Alistair had been right. The lights on the moor didn’t care about bars or batteries. But they remembered the family that kept coming back to ask — and they remembered exactly how much pressure it took to make you listen.
