The Last Girl on the Rails - Tide-Cleaving Scroll

Greasy green hemp cord had tangled itself around the third knuckle of Tess’s left index finger, digging into the tender meat until the skin turned the color of raw lard.

She didn’t yank it loose. If you yanked a wet three-ply bight when sixty pounds of lovesick, hyper-muscular merfolk prince was leaning over your shoulder, the knot slipped into a hard half-hitch that took an awl and ten minutes of swearing to pick apart.

“Watch the loop,” Tess said, her voice gravelly from two hours of breathing recycled charcoal air inside the localized acoustic bubble. She kept her wrists low, letting the pinkscaled beast see every tuck of the running end. “Over the standing part, through the bight from underneath, around the back of the post, and back down through the eye. That’s a bowline. A six-year-old on a Boston fishing pier can tie one in four seconds. You pull it, it locks; you break the back, it falls apart. Try it.”

Beside her, hovering three inches above the woven kelp mat, Prince Pinky a massive, rumbling laugh escaped sigh that rattled the brass buttons on Tess’s windbreaker.

The young merfolk royal was still terrifyingly broad―seven feet of corded magenta muscle, his jawline looking like it had been chiseled out of purple granite, his fighting fangs clicking against his lower lip with every wet breath. But the wild, psychotic neon-pink glare in his eyes had begun to fade into a dull, exhausted lavender as the Level 2 Love Potion burned through the last of his alien glycogen reserves.

Pinky took the hemp rope in his massive, webbed claws. His thick fingers, each tipped with a three-inch black talon that could have sheared through a pine joist, fumbled clumsily with the twine.

“Through… the eye?” Pinky boomed, his voice still vibrating in that deep, chest-thumping baritone, though the pitch cracked slightly on the vowel. “Like… like threading a bone needle to stitch a nursery net for our hundred spotted offspring?”

“Just tie the rope, Pinky,” Tess muttered, rubbing the bridge of her nose. “Nobody is laying any eggs today. If you drop the running end again, I’m taking the strawberries back.”

Across the floating grass platform, three of the younger princesses―the ones with shimmering emerald, gold, and violet tails―were huddled in a tight circle, their webbed fingers flying as they competed to see who could braid the most intricate nine-strand cargo lashing around an empty nautilus shell.

Giving bored, hyperactive aquatic apex predators complex knot-tying puzzles had turned out to be the single smartest tactical decision Tess had made since landing in Sector-37.

When an alien royal court spent four centuries swimming in circles with nothing to do between seasonal fish migrations, introducing them to sailor hitches, sheepshanks, monkey’s fists, and multi-tier diamond lashing was like dropping an entire crate of smartphones into a middle-school detention hall. It channeled the volatile hormonal surge of the misfired potion into obsessive, mechanical focus, keeping forty sharp claws busy while the metabolic spike washed out of their systems.

Up on the megalodon-skull throne, the Merfolk King had finally stopped roaring with laughter.

The massive old sovereign was sprawled sideways across his coral dais, his twelve-foot blackened void-steel trident propped casually against his knee while he used a broken piece of mother-of-pearl to pick a scrap of roasted squid from between his rear molars. His grey scales had faded from plum crimson back to their natural mottled iron color, though his gill slits still whistled every time he exhaled a cloud of stale alcohol vapor.

“Look at that,” the King grunted, his deep bass voice echoing through the beryl vault like distant thunder. “Two hours of twine, and the boy hasn’t smashed a single crystal pillar. Brururu, you should have bought ropes from the surface traders fifty years ago instead of feeding them to the trench crabs.”

Princess Brururu drifted down from the upper gallery, her long cobalt tail moving with that effortless, liquid grace that made human walking look like a clumsy industrial accident.

She didn’t look amused. She looked like an older sister who had spent the entire morning cleaning up after an unruly frat house, but when her navy eyes met Tess’s over the top of the acoustic bubble, there was a grudging, unmistakable flicker of profound respect behind the dark lenses.

“His shoulders are shrinking,” Brururu noted, pointing a claw at her younger brother.

Tess looked.

It was happening fast now. The cartilage in Pinky’s collarbones gave a series of soft, wet pops as the endocrine surge collapsed. The seven-foot magenta behemoth visibly deflated, his bicep cables smoothing out, his square jaw softening back into the rounded, petulant face of an overgrown teenager. His tail lost its aggressive, armor-plated bulk, returning to a delicate, pale water-lily pink that trailed limply against the coral floor.

Pinky blinked his milky-pink eyes three times, looked down at the frayed hemp rope in his webbed hands, then looked up at Tess’s drysuit.

His face turned a violent, mortified shade of boiled shrimp.

“Did I…” Pinky squeaked, his voice returning to its normal, high-pitched soprano register. “Did I tell a dry-lander from the iron tracks that she was going to lay a hundred eggs in my black sand nest?”

“You did,” Tess said, not cutting him an inch of slack. “You also tried to choke me with a fivepound string of red pearls.”

Pinky gave a strangled, piping whimper, buried his face in his webbed hands, and rolled off the floating grass platform into the open water, swimming toward the lowest drainage culvert at ninety miles an hour without looking back.

Brururu breathed a long, slow hiss that vented a stream of tiny bubbles from her neck gills.

“He won’t leave his sleeping cave until the moon turns twice,” the elder princess said, stepping into the edge of Tess’s air bubble with a soft, wet shuck. “Which means the royal nursery will finally have some quiet.”

She turned toward the rear of the chamber, clapping her webbed hands twice.

Four heavy palace guards―massive, dark-scaled bull merfolk wearing breastplates beaten from raw black iron―drifted forward carrying an array of cargo that made Tess’s spatial ring tingle with raw asset density.

They laid eighty heavy, rectangular bolts of folded fabric onto the floating platform.

Sirensilk.

The material didn’t look like textile; it looked like sheets of frozen ocean water that had been spun into thread by an artisan who understood light refraction. It was pale silver-blue, cool to the touch, and when Tess ran the rough palm of her hand across the top bolt, the fabric slipped through her calloused fingers with zero friction―so slick and frictionless it felt like touching cold mercury.

Beside the silk sat a small, carved clam-shell box holding five glowing blessing pearls.

Each pearl was the size of a plum, three deep sea-green and two rich, dark crimson, pulsing with an internal, rhythmic luminescence that warmed the air inside the bubble by three degrees.

“This satisfies the ledger for the fifty gallons of snake-bile liquor, the forty pounds of berries, and the cakes,” Brururu said, her tone businesslike, though her tail flicked with quiet satisfaction.

“And the knot lessons were complimentary,” Tess said, stowing the eighty bolts of silk into her spatial warehouse with quick, fluid taps of her interface ring.

Brururu lingered. She reached into a hidden leather harness beneath her left gill-cowl, pulling out an eight-inch cylindrical case made of cured, dark green kelp-leather, bound with three strands of dried sinew and capped with a polished disc of mother-of-pearl.

The case was ancient. The kelp had darkened to the color of wet slate, its surface incised with hundreds of tiny, flowing wave-runes that hummed with a faint, chilling draft that made the hair on Tess’s forearms stand up.

“My father gave you the silk because he is an old drunk who loves burning water,” Brururu said quietly, her navy eyes locking onto Tess’s unblinking face. “I am giving you this because you did not try to steal my sisters’ pearls when they were out of their minds on your poison, and you did not laugh at my brother when his pride broke.”

She held the kelp cylinder out across the space between them.

“What is it?” Tess asked, not reaching for it immediately. Out on the rails, taking an unvetted gift from an aberrant royal was an easy way to end up with a soul-curse sewn into your marrow.

“A manual,” Brururu replied, her voice falling into a reverent, rhythmic cadence. “Three hundred years ago, before the Great Cataclysm tore the rails through the deep trench, our people did not fight with tridents from the mud. We had Tide-Wardens. Warriors who walked the boundary between the spray and the rock, who understood that water cannot be stopped by iron because water does not fight the blow―it swallows the blade and returns the pressure tenfold.”

Brururu pressed the cylinder into Tess’s gloved hand.

“The humans who came before you tried to swing their iron axes like butchers hacking beef,” the princess continued. “They died because their movements were rigid, noisy, full of pride. Your Gale Blade cuts with compressed air, but air is just thin water. Read the treatise. Learn to let the cut flow like a winter tide, and the next time you face a void-beast on the open track, you won’t need to break your wrists to find the bone.”

Tess popped the mother-of-pearl cap.

Inside lay a single roll of paper-thin shark vellum, covered in dense, sweeping brushwork diagrams showing a slender figure executing three distinct combat postures amidst raging ocean currents.

Tess closed the cylinder, tucked it securely into the breast pocket of her Kevlar vest right next to the ascetic’s fingerbone, and looked Brururu dead in her black-and-navy eyes.

“You’re an honest dealer, Brururu,” Tess said, extending her right hand.

Brururu looked at the five bare human fingers, hesitated for half a second, then reached out and clamped her cold, webbed claws around Tess’s wrist in a firm, bone-jarring grip that smelled of clean brine.

“Get back to your iron box, Caldwell,” the princess said, her mouth curving into a sharp, toothy smile. “And next time you cross Platform 08, bring more of the red berries. If Pinky is still sulking, I’ll feed them to the sharks.”

Tess slipped her rebreather mouthpiece back between her teeth, pulled the dive mask over her brow, and stepped backward out of the acoustic bubble into the cold, silent twilight of the ocean floor.

The lead-weighted gaiters felt three times lighter now, buoyed by the passive field of the five blessing pearls nestled in her pack.

She kicked her flippers twice, shooting upward through sixty feet of glowing crystal spires like a silver dart, leaving the silent realm of the merfolk behind as the iron silhouette of The Iron Bastion loomed against the lavender sky above.
