When a courier arrives bearing a letter tied with silver twine and no return seal, you either pretend you are not home or fetch ink before curiosity curdles. I fetched ink.

The parchment smelled of myrrh and hot iron. Inside, one sentence: “Come to Al-Ramla Oasis and learn why the dunes bleed.” Below it, a sigil I did not recognize – half crescent, half set of jagged fangs. No signature, only a down-payment of ten amber coins, each stamped with an unfamiliar sultan's profile.

I, Sabirah el-Khayyam, itinerant naturalist and occasional hoax debunker, have followed stranger invitations. A cryptid that makes desert sand bleed? That promised a chapter fit for The Wandering Ledger. I packed my brass spyglass, three weeks of provisions, and considerably more optimism than the situation deserved.

Al-Ramla lies where the sandstone channels of the interior give way to dunes as tall as cathedrals. Caravans seldom stop there. The oasis shifts on maps the way mirages shift on horizons – reliably present in rumor, elusive in practice.

I joined a spice caravan escorted by the Bronze Mamluks, mercenaries who trade sword service for coin and strong coffee. Their captain, Tariq of the Seven Scars, warned me of recent troubles: jackal howls from empty wells at midnight, travelers waking to find every glass object in camp reduced to pale powder. The locals had a name for the responsible party – Al-Saqq, the Glass Jackal, a creature whispered of since the old world before the Meteor. It prowls moonlit dunes, devours reflections, and leaves behind footprints that bleed into glass.

I filed this under superstition. Three nights into the journey, something tore open a cargo crate and shredded a full case of crystal vials without disturbing a grain of cumin. There were no footprints. The mamluks muttered prayers older than their scimitars, and I quietly moved my notebook to the inside of my coat.

Al-Ramla greeted us as a cluster of date palms around a lake no larger than a banquet table. At noon the water reflected the sky with unsettling precision. At dusk the reflection vanished entirely, leaving the surface black and flat as polished obsidian. Tents ringed the grove, each stitched with talismans. My mysterious patron waited beneath the largest palm: Elyas ibn Harun, scholar of the unseen, eyes rimmed red from what appeared to be several consecutive nights without sleep.

He led me to a low ridge where a dune had collapsed. The exposed interior glistened. Rivers of ruby-colored glass ran through the sand like veins through a body, and where the glass ended, the spoor began – canine paw prints, large as lion pads, pressed not downward into the sand but upward through it, as if molten glass had risen to meet invisible feet. I measured the stride. Whatever made them was roughly the size of a draft horse.

“The oasis is dying,” Elyas said, in the tone of a man who has been saying it to himself for some time and only recently found someone worth telling. “Each time the Jackal drinks the moon, more water turns to mirror. The well will not last the season.” He believed the creature to be Shard-born, drawn to any surface that echoed the night sky. He needed documentation. He needed, more pressingly, a plan. My task was to provide the first and help develop the second without getting devoured in the process.

We laid an array of polished bronze bowls across the dune face, filled with date liquor, spaced like stepping stones into the dark. I rigged trip wires of silk attached to phosphor flares – silent triggers, bright results. Then we settled beneath a rag-stitched blind and waited for the desert to cool and the sky to open up.

Past midnight the air began to vibrate with a sound like a wet finger drawn around the rim of a wineglass – soft, then rising, then impossible to ignore. The moon reflected off every grain of sand as though the desert had become a single sheet of glass. The shape that emerged from the dark was four-legged and lean, faceted like a gemstone carved into the rough idea of a jackal. Its body refracted starlight. No organs were visible, only overlapping planes of translucent green shimmer, edges catching and bending whatever light touched them.

It padded toward the nearest bronze bowl. Where each paw made contact with the earth, glass solidified beneath it, and the sand around the impression bled upward in thin ruby threads to fill the mold. I understood then what the dune's exposed interior had been telling us. The creature did not leave prints – it made them, continuously, involuntarily, wounding the desert simply by existing inside it. My quill could barely keep pace.

The beast lapped at the liquor, its tongue a shard-thin sliver that left hairline fractures in the metal bowl. A flare snapped alight and bathed it in magnesium brilliance. It did not flee. It looked directly at us. Its eyes were voids packed with pinpoints of light – an inverted sky, a night that had been turned inside out. Then it opened its jaws and howled.

Sound became shrapnel. My spyglass burst in my hands. Sand whipped upward and vitrified mid-air, raining back as needles. Elyas's obsidian talismans cracked in sequence like a string of argument reaching its conclusion. Mamluk guards rushed from camp with scimitars drawn, and those blades snapped on contact with the creature's hide, the metal dissolving into bright flakes that spiraled inward and disappeared. It fed on reflections, and a polished sword is nothing but a long, narrow mirror.

Captain Tariq raised a mirrored shield – a coastal war heirloom, silver-backed, meant for deflecting archers and impressing dignitaries. The Jackal lunged and bit into its own distorted face looking back at it from the metal. There was a detonation of light without sound. When sight returned, Tariq was on his back in the sand, breathing, eyes open and glassy, the shield gone entirely. The Jackal retreated limping, its form flickering at the edges like a candle seen through bad glass.

Elyas pulled me into the date palms. “It's wounded. A Shard creature that feeds on reflections – deny it mirrors and we starve it.” He was already calculating. I was still watching the place where Tariq's shield had been.

We spent the remaining dark hours covering every reflective surface in camp – blade steel, water skins, boot buckles, the brass fittings on my instrument case – in mud, cloth, anything that would break the sheen. The oasis became a blot. No glint, no gleam, nothing to drink sky from.

Under the following night's starlight the Jackal prowled the perimeter, slower now, searching. By dawn it left clear quartz where it had been leaving ruby glass – a change in the color of its damage, a sign that the creature's reserves were thinning. But the more it weakened, the darker the well water grew, as if the Jackal's hunger had found a new surface to strip. Children told their parents that their reflections no longer smiled back correctly. Elyas made note of this with the detached diligence of a man who has learned to record the consequences of his mistakes rather than dwell on them.

He confessed on the third night. The Jackal was no discovery. He had summoned it, months prior, while experimenting with star-reading shards – Shardisite configured as a forecasting instrument, meant to show him futures the way still water shows a face. Instead it had shown him an appetite. “I only wanted to know tomorrow,” he said, hands flat on the table, not shaking. The shaking had stopped by then, which was somehow worse. “It showed me nothing. Not because it would not. Because tomorrow is a desert, once the Jackal feeds.”

With nothing left in camp to reflect the sky, the creature fixed its attention on the one surface we had not been able to dull: the Black Well itself. At the full moon its water held the sky like a cupped hand. Elyas's proposal was straightforward and awful. Lure the Jackal to the well with the brightest reflection available. Collapse the mouth with alchemic saltpetre charges once it leaned in to drink. Entomb it in its own glass, in the dark, where there is nothing left to eat.

I pointed out that the well was the reason Al-Ramla existed. Without it the oasis would be uninhabitable inside a season. Elyas acknowledged this without changing his position. “Better a dead oasis than a desert that keeps losing its reflections,” he said. “Give it long enough and there will be no still water left in Arabia. No mirrors. Nothing that holds a face.” I did not have a better plan. I have spent considerable time since wishing that I had.

The flares went up around the well and cut the moonlight into the pool's black surface in long white columns. The Jackal came across the sand, ribs visible as fault lines through its faceted hide. It leaned over the edge. Elyas spoke the ignition word. The charges went in sequence, the walls came down, and water and sand and accumulated glass cascaded inward in a sound like every window in a city breaking at once.

When the dust cleared, the well was gone. In its place, a bowl of fused obsidian, smooth and dark and still. The Jackal was nowhere. In the glass I saw starlight moving where my own reflection should have been.

The caravans left. The date palms withered by the following month. Elyas stayed, cataloguing the obsidian bowl with the systematic attention he had presumably applied to every other project that had ended in catastrophe. One morning I came to find him standing at its edge, unmoving, staring at his own reflection in the black surface. His eyes had become glass. His body was present and empty, holding only the sky he was looking into. The Jackal had not been entombed. It had found the largest mirror we had made for it, and moved in.

I buried Elyas in sand that rang faintly when the wind crossed it. I did not look into the obsidian bowl before I left.

I travel now with my mirrors wrapped in cloth and my inkwell kept lidded in the dark. Some nights the stars inside the wrapped glass shift slightly out of alignment with the sky outside, as though something in there is pacing. The bleeding dunes are quiet. But merchants along the southern routes report that their faces have begun to behave strangely in calm water – expressions arriving a half-second late, smiles that linger after the feeling has gone.

Mysteries do not die. They migrate. And somewhere beyond the next caravan route, a child will polish a shard of glass and wonder why the moon wears fangs.
