Resin-wicks hissed, blurring acrid Veinfire with sweeter smoke. The Mother’s Heart glowed faintly, veins dim but steady.

  Through the torn stone, the night still watched.

  Kael sat rigid on a resin-stone bench, chest bandaged in moss-soaked wraps while the physician’s fingers pressed along his ribs and shoulder, counting the damage in small, worried sounds. His spear leaned within reach, as if even wounded he refused to part with it.

  On the other side of the chamber, nurses circled Aethel in a slow orbit. They lifted her hands, turned her arms, brushed ash from her hairline, searching for blistered flesh that was not there.

  “Nothing,” one whispered.

  “Veinfire doesn’t leave nothing,” another answered.

  Their voices thinned to a hush of disbelief.

  “She should not be standing,” the physician murmured, more to himself than to her. “No burns. No cracks. Even her veins are—”

  Aethel flinched at the way they all stared.

  “Enough.” Her voice cut clean through the smoke. “Leave us. No visitors.”

  They hesitated only a breath, then drifted out past the torn stone, their whispers trailing after them like ghosts.

  Silence settled. Aethel, unmarked but trembling with after-fire, bent to sweep ash into a bowl.

  The twins wordlessly joined her. Lyren stacked broken jars like a crooked tower; Syra folded cloths into neat squares. Lyren hummed off-key until Syra gave her a glare.

  “We’re saving your dignity, Aethel,” Lyren said with a grin. “Imagine the Council stepping in to see this disaster.”

  “I’ve fought in caverns that looked cleaner,” Kael muttered.

  Aethel shot him a glare.

  “You could be less helpful.”

  “I could,” Kael said dryly. “But you’d grow soft.”

  Even Syra smiled.

  When the chamber quieted, Aethel lowered herself beside them.

  “Tell me a little about yourselves.”

  Lyren leaned back on her palms, confident.

  “Well, I’m fifteen Falls, seven Brims, fourteen Shades, six Slips, and twenty-three Ticks old… but who’s counting?”

  Syra’s voice slipped in softly.

  “…I was born only a few Ticks later. Our mother didn’t survive. They say it’s the cost of twins. Sometimes I think,”

  Aethel cut her off, firm and warm.

  “No. Never your fault. The Mother takes what She takes. The cost was Hers, not yours.”

  Lyren looked away, flicking resin dust. Her voice came rough.

  “Our father kept us alive until the Council sent him to dig the lower caverns. The rock crushed him. They called it necessary.”

  Her voice sharpened. “That word tastes like ash.”

  Aethel nodded slowly. “You were right to be angry.”

  Lyren blinked, then forced a grin.

  “No big deal. I had Syra. That’s all we ever needed.”

  “All we had,” Syra whispered softly.

  A silence pulsed.

  Then Kael frowned mid-thought, brow twitching. “Wait… say that again. You’re what?” he asked, sitting up straighter.

  Lyren blinked innocently. “Fifteen Falls, seven Brims, fourteen Shades, six Slips, twenty-three Ticks. Give or take a half-Stride.”

  Kael rubbed his temples like the numbers physically hurt him. “That’s not real.”

  “It’s real to us,” Syra said, deadpan.

  “Sounds like a fever dream,” Kael muttered. “What even is a Slip?”

  “Oh no,” Lyren whispered, eyes gleaming. “He doesn’t know.”

  “He’s too old,” Syra said solemnly. “The formal type.”

  “Probably still counts in Dekors,” Lyren said, elbowing her.

  Kael looked between them like they were both growing moss. “Dekor is the standard.”

  “That’s what old people say,” Lyren said brightly.

  Syra nodded. “And Council ghosts.”

  Kael groaned. “Just, what’s a Tick? Start small. One unit. Explain it to me like I’m... not from a cave.”

  “Oh, we can do that.” Lyren grinned. “Ready, Syra?”

  Syra tilted her head thoughtfully. “Go.”

  Lyren held up one finger. “Okay. A Tick is the sound of a drip from the cistern. Regular. Steady. You feel it more than you count it.”

  “Water drips?” Kael repeated flatly.

  “We didn’t have clocks, old man,” Lyren said, grinning. “So the Ticks told us when to move. If the pipe was leaking fast, you better hurry. Slow drips meant you had time.”

  Syra added, “It’s not precise. But it’s right. For us.”

  Kael muttered, “So it’s chaos.”

  Stolen content warning: this tale belongs on Royal Road. Report any occurrences elsewhere.

  “Rhythmic chaos,” Syra corrected. “Next is a Stride.”

  “One full round of pacing the eastern ring of the cistern,” Lyren said, pacing it out with exaggerated stomp-steps. “About fifteen Ticks, if you’re not dragging your boots.”

  “Then comes the Slip,” Syra said. “Four Strides. Enough time to nap, eat, or lose a bet.”

  Kael raised an eyebrow. “How often are you losing bets?”

  Syra looked away. “Depends on the Brim.”

  “Which is next!” Lyren clapped. “A Brim is thirty Shades.”

  “What’s a Shade?” Kael sighed.

  “A Shade is twenty-four Slips in the Vault, from when the light crystals dim to when they return,” Syra said, her voice gentle.

  Kael blinked. “So no sun.”

  Lyren mock-gasped. “What’s a sun?”

  Syra smirked. “Must be a surface joke.”

  “All right,” Kael grumbled. “So how long’s a Fall?”

  Lyren puffed up like she’d been waiting for that one. “Fall is the big ledger mark, Ten Seasons. You don’t feel a Fall the way you feel a Season; you count it.”

  “It’s one Dekor,” Syra added softly. “A Season is one Veynar, twelve Brims, and you feel it. The air shifts, steam echoes different, the old healers nod and say, ‘New Season.’ A Fall is ten Seasons, marked on the wall and in the ledgers.”

  Kael looked between them, stunned. “…Finally. Helpful.”

  “Sure it was,” Lyren said, beaming.

  “We educated you,” Syra said solemnly.

  Kael pointed at Lyren. “You made half that up.”

  “I felt all of it,” she declared proudly. “And that’s how time works underground.”

  “You’re all mad.”

  Lyren curtsied, feet scuffed with resin dust. “Thank you.”

  Syra leaned closer to Kael, half-whispered like a secret, “You still think in Dekors, don’t you?”

  Kael narrowed his eyes. “Threx and Dreth, mostly.”

  Lyren gasped again, more dramatic than before. “He’s counting Drethin!”

  “He probably says ‘Luthan-eth’ unironically,” Syra whispered.

  Kael looked to Aethel for help. She was grinning behind a hand.

  “You’re all enjoying this too much,” Kael muttered.

  Lyren threw an arm around his shoulder. “That’s how you know you’re family.”

  Syra added, “Even when you don’t understand a Tick we’re saying.”

  Aethel set down the bowl of ash, voice smooth but softened.

  “What they’re saying, Kael… is they’re fifteen.”

  She didn’t look at the twins, she looked at him. So he would understand. So he would believe them.

  Then, like she couldn’t help it, she added, just under her breath:

  “…And maybe a quarter-Stride more, give or take a Brim.”

  Lyren stared at her, stunned.

  Syra blinked like the light crystals had just flickered.

  Aethel gave them the smallest shrug.

  Lyren clutched her chest. “She gets it.”

  Syra whispered, “She’s fluent.”

  Kael just sighed and leaned back again. “Mother help me.”

  “Besides, I’m the best spiced-root baker in the Vault. Ask anyone. Syra can’t cook worth a Tick, but she hums to the bread and somehow it rises better.”

  Syra flushed. “That isn’t true.”

  “It’s true. Magic bread,” Lyren said.

  Aethel laughed, a sound she hadn’t expected here.

  Kael’s eyes lifted, voice steady. “Careful. Invite them in and you’ll drown in bread.”

  “You say that like it’s a curse,” Lyren shot back.

  “Depends on who’s baking,” Kael replied.

  “I don’t burn it,” Syra murmured.

  “Then perhaps there’s hope for you yet,” Kael said, almost smiling.

  “So… family?” Lyren asked. “That what this is?”

  Kael’s gaze went to Aethel. “It always has been. Even when it was just the two of us.”

  Lyren leaned forward, mischief sparking. “If I join, do I get a spear? Or just hum at bread with Syra?”

  “Both,” Kael said shortly. “Aethel doesn’t keep the useless.”

  “Don’t scare them,” Aethel said, rolling her eyes.

  “Not scaring. Warning. Walk with her, you walk through fire.”

  The twins exchanged a glance. Lyren’s grin widened; Syra’s lips parted in quiet awe.

  “Fire, huh? Sounds familiar,” Lyren said.

  “…We’ve already endured,” Syra added.

  Kael gave a curt nod.

  Aethel reached for their hands. “We don’t have much. No home but this chamber. No riches, no Council favor. Just each other. A raggedy family, patched together from what’s left. But it’s yours, if you want it.”

  Both froze.

  “Truly?” they asked together.

  “Truly,” Aethel said.

  Lyren’s grin came roaring back.

  “Fine. But keep up. We’re twins, everywhere at once.”

  Syra smiled quietly, an echo in perfect harmony.

  Kael leaned back against the resin-stone, muttering just loud enough for Aethel:

  “Raggedy, yes. But stronger than the Council knows.”

  Where her shoulder had rested, two pale crescents had seared into his skin.

  Aethel let the words settle. For the first time since the shard, the chamber didn’t feel like a trial. It felt like a beginning.

  Five Shades Later.

  The chamber didn’t just shift, it filled. With voice. With warmth. With things that hadn’t lived here before.

  The twins had nested into the left alcove like they’d always been there. Syra stacked everything into neat cubes. Lyren scattered everything into controlled chaos. One painted glyphs in the steam of the bathwater; the other sang badly through her teeth.

  Kael healed fast.

  Too fast.

  “Drink this,” said the physician, handing him a thick clay cup. “Old surface remedy.”

  Kael sniffed it. “Boiled fungus and bad decisions.”

  “Drink it anyway.”

  He did. Coughed. Eyes watered. “That’s death.”

  “Three Shades from now, you’ll bless me.”

  By the second Shade, Kael was up. By the third, he was stretching in full armor. By the fourth, sparring with Lyren. Who bit him.

  “Tick’s worth of pain,” she muttered, smirking. “Now we’re even.”

  They turned his spear rack into a clothesline and used his blankets to build a hide-fort.

  When Kael yelled, they ran behind Aethel and peeked out like guilty birds.

  She didn’t scold them.

  She did laugh.

  One Dreth Later.

  The chamber didn’t just shift, it woke.

  The warmth they’d built, blankets, bread, soft scolding's and bad singing, held for a breath.

  Then the walls pulsed once. Quiet. Like a vein catching rhythm.

  The Mother’s Heart stirred.

  A second pulse followed, deeper. Not heat. Not sound.

  Amber light bled from its surface.

  Then,

  It spoke.

  Not aloud.

  The words came like heat through stone, pressed into marrow.

  “Spiral Lens.”

  The name echoed inside them, etched in breath, bone, blood.

  Kael stood first, hand resting on his spear but not lifting it.

  Aethel didn’t move, she listened. Her eyes flicked to the far corridor.

  The amber pulse intensified.

  The Spiral Lens had been called.

  And the Veilglass would answer.

  They entered the Veilglass chamber.

  It had changed.

  Where once the glass flickered faint with forgotten echoes, it now pulsed with amber resonance, deep-honeyed light, thick as syrup, casting long shadows behind them.

  Above the dome, the constellations reformed.

  They didn’t just appear, they emerged, rearranged. As if the glass was remembering their shape from long ago.

  One constellation hovered lower than the others.

  It didn’t flare like Aries, brash and bold.

  It didn’t hum like Gemini, two points strung by thread.

  This one curved wide, arched like a shell or a watchful spine.

  Its stars weren’t bright, but they watched.

  Each glimmering point flickered slowly, almost breathing.

  It was a guardian shape, patient, eternal.

  And then,

  The center of the Veilglass tightened.

  A ripple spread outward, and a single glyph at the base of the dome ignited.

  Amber deepened.

  The glass didn’t shimmer.

  It drew.

  A thread, no, a star, from the curved constellation above began to pull downward, not falling, but offered.

  Its descent made no sound.

  But all of them felt it, in the jaw, the ribs, the spine.

  The star dropped into the center of the Lens and landed.

  Not like a stone. Like a seed.

  A low vibration passed through the floor.

  Glyphs uncoiled across the dome, layered in spirals, amber on amber, until the Veilglass opened.

  It didn’t split.

  It invited.

  A threshold bloomed in its center. Amber light curled at the edges, warm as breath, vast as sky.

  Aethel’s voice cut through the hush.

  “Wait for us. We’ll be right back.”

  She was firm, but her hand lifted slightly, as if to stop them from stepping too soon.

  But Lyren was already turning.

  Her jaw clenched. She grabbed Syra’s wrist, hard, instinctive, and real.

  She didn’t ask.

  “Not if we beat you there.”

  And she ran, dragging Syra into the spiral, into the light, into the open Veil.

  The threshold didn’t close.

  But the chamber exhaled.
