Inside the Earth Vein, Aphelia froze like a statue carved into bedrock, every shred of her strength crushed into a needle point. She watched through Aether’s sight, like a hawk over black water, frantic to track the source of that terrible force. The pressure it cast on her heart was heavier than the Origin adrift in outer dark.

“Aphelia…”

Hrok couldn’t wield Aether now, yet the air around her thickened like wet felt. You don’t need a blade to know a storm’s coming; when power congeals to substance, even those cut off from Aether feel the air bend. Even mortals insulated from Aether sense the world tilt.

The most obvious change was the air gone dense, a vise on the lungs, a mountain on the chest. Aphelia threw up a wall of Aether, a clear sea around the two of them, shouldering most of the weight, so Hrok wouldn’t die crushed like a reed in a flood. Yet through that sheath of Aether, Hrok still felt that tide of force gnawing close.

Panic hit first, then suspicion flared like sparks. Why didn’t our time in the Earth Vein draw this thing’s eye? Is it because Aphelia’s too bright a sun to notice a firefly? Hrok scanned the dark flow, eyes skimming like swallows, trying to catch every ripple.

The Aether within the Vein still streamed like a river under ice. Nothing looked wrong—yet the pressure breathed at her nape. Hrok didn’t think a bluff could weigh like a mountain. Neither did Aphelia. Past a certain depth, illusions are smoke against a blade; a shadow can’t fake a cliff’s edge.

By now Aphelia had reached what humans call a single blade cleaving ten thousand arts. Her powers hadn’t multiplied; her answers had. With a handful of forces, she could meet a thousand storms. That was how those at her height fought—knife-simple, ocean-wide.

Hrok opened her mouth to speak, but the Earth Vein’s braided Aether flickered. A crooked phantom budded out of the current, a dark ripple stepping out of a mirror. Aphelia didn’t hesitate. Crimson Fire bloomed like a rose, wrapped Hrok, and hurled her back. The shadow slammed into Aphelia like a wave swallowing a torch.

“Aphelia!”

Thrown wide, Hrok reached out, fingers clawing at smoke, wanting to drag Aphelia with her in a single wrench. But without Aether she was only mortal—arms in water, feet in mud—and she watched, helpless, as the phantom swallowed Aphelia whole.

Hrok scrambled up, blood singing, and lunged for that shroud. Several transparent figures flashed past like glass fish in a black tide. They sank into the shadow first. The instant they merged, the shadow winked out like a snuffed lamp, and in its place hung a strange Rune, etched in light, humming with Thunder.

“We’re here… Ur—”

A familiar voice brushed her ear, and pain split her skull like frost through stone. Black Aether pricked her mind like needles. Aphelia dragged in a breath, and her eyes snapped open to night-bright clarity.

“We’re here… Urd. The one we had to bring, I’ve brought her. Give me the thread.”

Skuld stepped off a magic carpet the color of dusk. At her voice, the girl weaving the threads didn’t even turn. She loosed what she held and walked toward the three. The thread didn’t fall. It hovered like spider silk caught in dawn light, and when Skuld took it, the weaving resumed, soft as rain.

Wait. Where is this?

Aphelia focused. A giant tree loomed like a pillar holding up the sky. Colors shone bright as enamel, yet the air was winter-cold. And the three figures before her… This was the audience with the goddess of fate she’d had with Odin. What happened? Had she slipped into another time again?

“Pleased to meet you… no, I should say, long time no see, Loop of Errancy, Ouroboros.”

The girl looked young, yet her voice rang airy as bells over snow, and her gestures were a river’s grace, older than her face.

She didn’t address Odin. She moved to Uroboros instead, and spoke like a feather touching glass.

“Long time no see? I don’t recall a fortune-teller like you in my past.”

Aphelia wanted to lift a hand and stop Urd. Because this was where it all began—the moment Urd tore the false Uroboros out of her body. But her mouth was sealed like ice over a lake. Her limbs were locked into her own skin.

Uroboros gave a sour smile, a knife-edge of teeth. The other had named her origin right out of the gate, but Uroboros was certain she had never seen Urd in all her long seasons. If she had, the girl would already be part of her loop, a bead on her serpent spine.

Anyone who claimed to see time drew Uroboros like a moth draws fire.

“Of course you don’t remember, Ouroboros… no, I should call you Uroboros. At least this you hasn’t seen me. And I’m no charlatan. I’m only a mortal peeking from the cliff edge of fate.”

Urd took the rudeness like calm water takes moonlight. She was a maiden to the eye, yet her ease was an autumn harvest, ripe and sure.

To most, those words would plant awe and guesses, painting Urd as some mist-cloaked sage. To Uroboros, a being too singular to be compared, it was just smoke and mirrors.

A rule is a rule because, across countless worldlines, it’s the lone spine that spans the cosmos. Uroboros, a piece of the world’s own law, would never admit another her existed. Couldn’t allow it. If she did—if even her shadow agreed—then the rule called Ouroboros would crack like a mirror under a hammer. The world would flip inside out.

Imagine a world without Errancy, a sky without clouds. Everything named correct. Terrifying. Kindness is deemed correct; brutality too. Life is correct; death as well. Contradictions lose their teeth and fuse, and what’s born of such cold union can’t be joy. From such twistless order comes a twisted world.

As Errancy made flesh, Uroboros didn’t mind watching such a world bloom like a white flower. But not at the price of erasing herself—concept and all—from every cosmos. She let that thought go, like ash on wind.

Aphelia already understood. The Uroboros before her was only a stand-in with short-term memory, borrowing the serpent’s power. Of course she wouldn’t confess. But then why was Aphelia here? If it wasn’t time travel, what rethreaded this memory through her?

Uroboros waved Urd’s words away like smoke.

“If you met me on another line, this world would’ve already ended. You wouldn’t be standing here talking to me.”

Her smile tilted, contempt bright as a blade. In that moment, her nature showed like bone through skin. She had never been kind. She simply shared a trench with Aphelia and turned her face the other way.

Aphelia wanted to say as much. But she felt like someone had wedged her into her own body, tight as iron. She couldn’t twitch a finger.

Seeing the air spark, Odin didn’t step between them. She only tugged Aphelia a few paces back, a shield like a cloak. From that distance, as a watcher, Aphelia caught a flicker. On Urd’s fingers, the color shifted for an instant, like a fish flashing its belly. It was quick as lightning. She hadn’t seen clear. Bound and voiceless, she forced her sight to grip Urd harder, like a lens turned by a careful hand.

Odin found Urd’s words intriguing. The so-called Loop of Errancy surely spoke to the rule of the world. And Uroboros had been strange from the moment she appeared—beyond strange. From Aphelia’s view, their idea of Errancy was too narrow. The universe’s rules were born with the Origin. If there was Errancy, it was a face the rule wore, not a crack in it.

Against the giants, Odin’s Runes were a knife against a boulder. She survived now by the Aether Aphelia had poured into her when she dragged Odin back from death’s river. Anyone who holds Aether brushes a world-rule, or becomes one. That kind of conceptual distance stamps giants flat like footprints on dust.

But Uroboros? After she appeared, she showed a terror past ordinary measure. On the Golden Plain, the sky-devouring serpent rose, and Odin remembered every heartbeat. The legions of giants went down her gullet; half a host vanished like sand in a tide.

Back then, Aphelia shrugged it off as “my helping hand.” A smoke-screen of words.

Now Urd had named her. It wasn’t going to stay simple.

“Of course, of course. Be patient.”

Urd’s voice was soft as velvet. A silver glint slid through her bright eyes. Then she said:

“What if the you standing here isn’t you, Ouroboros?”

To Uroboros, it sounded laughable, a paper tiger drawn in charcoal. She parted her lips to sneer—

—but Urd spoke first.
