Chapter 2 – The Mud of Jorvik

ASTRID

I do not wait for the stranger to answer. The iron spearhead is still vibrating in the thatch, inches from her leg. If she hesitates, she dies, and the year of life I just burned to give her my balance is wasted.

I seize the thick, boiled-wool fabric of her strange black tunic and heave her backward.

We slide down the steep pitch of the longhouse roof. The rain is a sheet of freezing needles, slicking the rotting thatch beneath our boots. Below us, the alley is a narrow trench of churning black mud and overflowing cesspits, flanked by the high wattle-and-daub walls of the merchant quarter. Torches flare at the ends of the street. Gunnar’s men are spilling out of the main hall, their shouts tearing through the drumming rain.

“Find the witch! Seal the river paths!”

I twist in mid-air, kicking off the overhanging eaves to clear the waste-trench. I hit the mud rolling, the impact jarring up my spine. My left palm—bearing the fresh, bleeding cut that was supposed to be hers—burns like a hot coal.

The stranger lands beside me. She does not scream. The borrowed combat data in her nervous system forces her into a proper break-fall, dissipating the kinetic shock across her shoulders. But the moment she stops moving, she retches, her body rejecting the sheer, unnatural overload of someone else’s reflexes.

I grab her collar and haul her into the deep shadow between a tanner’s vat and a slatted wooden fence. The stench of fermented urine and rotting hides is thick enough to chew.

"Quiet," I hiss, pressing her back against the wet timber.

I peek around the edge of the vat. Three men with drawn swords are sprinting past the mouth of the alley. I know them. Sweyn, Hastein, and a young whelp from my own clan. My chest tightens. By surviving the pyre, I have broken the blood debt. Jarl Gunnar will not just kill me now; he will slaughter my brother’s crew. Every moment I draw breath is a death sentence for my kin. I am a walking ghost, and all of York will be hunting me for the silver Gunnar will place on my head.

The stranger is shaking violently. She reaches up, pressing her fingers against her throat, tracking her own racing pulse. Her dark eyes are wide, reflecting the distant orange glow of the burning roof.

She looks down at her right hand. The silver scar—the one that replaced the open wound she arrived with—is stark against her pale skin.

"You gave me your balance," she whispers. Her accent is atrocious, the Norse syllables mangled through a completely alien cadence, but the words are intelligible. "When we touched."

"I gave you an hour of my muscle memory," I reply, my voice flat. "And it cost me a year of my life."

She flinches as if struck. The shock in her eyes is not feigned. She understands the currency of the rune. She looks from her scarred palm to my bleeding one, the ledger of our physical trauma balanced by the magic.

"A year," she breathes, the weight of the sacrifice crushing the breath out of her.

"It does not matter. I was meant to burn tonight." I wipe the blood from my palm onto my trousers, smearing the charcoal of the Ehwaz rune. The connection is dormant, but the bridge is built. I can feel a faint, terrifying hum at the back of my skull—an echo of her sheer panic, separated only by a thin mental wall. "Can you run without my data guiding your legs?"

She swallows hard, looking at the treacherous, knee-deep mud of the alley. "I don’t know."

"Learn fast." I draw my short knife. "Because if you slow me down, I will leave you to Gunnar’s hounds."

FREYA

My lungs are screaming. The air is too dense, heavy with woodsmoke, ozone, and the coppery tang of fresh blood.

I am a battlefield archaeologist. I have spent a decade handling the remnants of violence. I have brushed dirt from shattered skulls, mapped the trajectories of fatal arrow wounds, and reconstructed the final, desperate moments of warriors who died a thousand years ago. I know history intimately.

But history is supposed to be dead. It is supposed to be quiet.

It is not supposed to smell like excrement and fear. It is not supposed to grab me by the collar and threaten to leave me to the dogs.

Astrid Ketilsdottir—the woman I excavated, the woman whose bones sat in a climate-controlled box in my lab not twenty minutes ago—is moving through the shadows of ninth-century York with lethal grace. I follow her, slipping in the vile muck, my modern boots offering zero traction in the deep, clay-thick mud.

My right hand aches with a phantom pain. The wound is gone, replaced by a smooth, silvery scar, but the tissue feels alien. Every time I look at it, a wave of profound cognitive dissonance threatens to snap my mind in half. I touched the sword. The blood touched the rune.

The physics of time have been shattered. But the academic in me, the ruthless, objective observer who built a career on cold facts, is screaming a different warning.

You cannot be here. You cannot interact.

If I save her—if Astrid does not die tonight, as the archaeological record dictates—then Grave 514 does not exist. The artifacts I found, the very sword that cut me, the grant money that funded my dig, the museum exhibition that was supposed to secure my tenure… none of it happens. The paradox is a physical weight, pressing down on my chest, heavier than the borrowed combat reflexes currently draining from my muscles.

We duck under a low-hanging thatched eave as a patrol of armed men heavily jogs past. I press my back against the wattle wall. The mud crumbles against my spine.

Astrid is standing inches from me, her chest heaving. The proximity is suffocating. I can feel the heat radiating from her skin. The heavy wool of her tunic is soaked, smelling of wet sheep and soot.

One of the passing guards barks an order, halting the patrol right at the mouth of our narrow gap.

Astrid moves instantly. She steps directly into my space, pressing me flat against the wall. Her left hand—the hand with the bleeding wound, the hand that matches my scar—slaps over my mouth.

Skin meets skin.

The rune sparks. It is not a willing transfer of skill this time, but a raw, uncalibrated leak of sensory data across the bridge.

A jolt of pure adrenaline hits my bloodstream, but it isn’t mine. It is hers. Through the contact of her palm against my lips, I feel her heart hammering against my own ribs. I feel the cold rain hitting her shoulders as if it were hitting mine. I feel the dull, throbbing ache of the burn on her left thigh, an injury I don’t possess but suddenly suffer.

I gasp against her hand.

Astrid’s eyes widen in the dark. She feels it too. The bridge is a two-way conduit. She is feeling my terror, my disorientation, my overwhelming sense of displacement. She flinches, her pupils dilating as she absorbs the sheer, alien scope of my modern mind.

She pulls her hand back a fraction of a millimeter. It is a deliberate break in pressure. A choice. She is giving me the agency to pull away, to sever the physical contact and shut the bridge down.

The guards are three feet away, their spears clanking against their wooden shields. If I make a sound, we are dead.

I do not pull away. I lean forward, pressing my mouth back against her bleeding palm, choosing the silence, choosing the connection. The sensory bleed washes over me again, overwhelming and intimate. I taste her blood, metallic and sharp. I feel the coiled, violent tension in her muscles, a predator backed into a corner but perfectly willing to tear its way out.

The guards move on, their footsteps receding into the mud.

Astrid drops her hand. The sudden absence of her sensory data leaves me feeling hollow, freezing, and entirely alone in the dark. She steps back, her breathing ragged, staring at her own palm as if it were a venomous snake.

"Do not ever draw from me without asking," she whispers, her voice trembling with an anger that barely masks her shock.

"I didn’t," I whisper back, wiping the smear of blood from my lips. "The rune did."

She turns away, her jaw set. "Keep moving. The river is our only way out."

FREYA

We weave through the heart of the trading quarter. The coppergate—the street of the cup-makers—is a labyrinth of narrow timber structures and deep artisan pits. The rain has lessened to a steady, freezing drizzle, but the market is not asleep. The chaos of Gunnar’s hunt has rippled outward.

Merchants are frantically packing their wares, terrified of the violence spilling into their stalls. Torches illuminate the panic.

I duck behind Astrid as we skirt the edge of a large, open-fronted structure. A merchant is yelling at his slaves, hastily loading wooden crates onto a handcart. A heavy leather sack slips from the cart, hitting the mud and bursting open.

A cascade of bright, glittering objects spills into the muck.

I freeze. My breath stops in my throat.

They are glass beads. Polished, multifaceted millefiori glass, streaked with vivid blue, yellow, and red.

I know those beads.

My mind superimposes a digital catalog image over the scene. Artifact cluster 402. Trench B. Deposited in an intact clay vessel, undisturbed for twelve centuries. They were the centerpiece of my early career, a pristine example of Carolingian trade networks reaching Viking York. They were found perfectly preserved, buried beneath a layer of intact ash from a fire in 895 AD.

But right now, in 889 AD, the panicked merchant is ignoring the spilled sack. A heavily armed Viking warrior, running to join Gunnar’s hunt, sprints blindly through the stall. His heavy leather boot comes down squarely on the pile of glass.

CRACK.

The sound is tiny, but in my head, it is deafening. The intricate millefiori beads shatter into a hundred worthless shards, ground deep into the filth.

They are destroyed. They will never be buried intact. They will never be excavated by a graduate student in 2012. I will never write my dissertation on them.

The timeline is not just fragile; it is fluid. And I am a sledgehammer swinging through a glass house.

I look up. The roof of the longhouse we escaped from is fully engulfed in flames. The wind is picking up, blowing the sparks toward the adjacent structures. The merchant quarter is catching fire.

"Astrid," I say, my voice cracking. "The fire. It’s spreading to the stalls."

She doesn’t even look back. "Good. It gives Gunnar’s men something else to fight."

"You don’t understand," I grab her arm, stopping her in the shadows. The historical record is flashing before my eyes. "This quarter didn’t burn until six years from now. I know the stratigraphy. The ash layer—it isn’t supposed to happen tonight. Our escape… we caused this. We are changing the timeline."

Astrid stares at me, her pale blue eyes flat and uncomprehending. "What is a stratigraphy?"

"It’s the dirt. The history." Panic rises in my chest, thick and suffocating. "Everything we touch alters what happens next. If you live, the grave I found you in vanishes. If this market burns, the people who were supposed to survive tonight will die. The future—my future—is unraveling right in front of me."

She steps closer, invading my space again. Her height is intimidating, her presence a solid wall of Viking reality against my abstract modern panic.

"I do not care about your future," she says, her voice a low, brutal rasp. "I care about the next ten minutes. I care about the blades hunting us. If your history demands I burn on a pyre so your dirt stays neat, then your history can rot."

She yanks her arm out of my grip.

"You chose to jump between me and the axe," she says, pointing a dirt-caked finger at my chest. "You touched the rune. You tied yourself to my survival. Do not weep for broken glass when our necks are on the block."

She is right. The sheer, ruthless pragmatism of her survival instinct cuts through my academic paralysis. I am not a detached observer anymore. I am a participant. And the blood on my hands is real.

ASTRID

The stranger’s face is pale, the bizarre concepts of "timelines" and "futures" visibly tormenting her. I do not understand the magic that spat her onto my funeral pyre, nor the strange, bloodless world she claims to come from. But I understand the terror in her eyes. She is a woman watching her home burn, even if that home is twelve centuries away.

But I cannot afford pity. Not when the hounds are loose.

We reach the edge of the industrial sector, where the smell of tanning gives way to the sharp, metallic tang of hot iron and crushed charcoal. The river Ouse flows sluggishly behind the buildings, a dark ribbon under the moonless sky.

I stop in front of a heavy, iron-bound oak door. The structure is built of solid timber, the roof vented for a massive forge. Smoke curls steadily from the opening, smelling of roasting slag.

"This is Einar’s forge," I whisper, checking the empty street behind us. "He is an old ally of my father. He owes my clan a blood debt. He will hide us."

The stranger—Freya, she called herself, a name of the gods worn by a woman who looks like she has never held a weapon—stares at the door. "If we go in there, we involve him. Gunnar will kill him if he finds us."

"Yes," I say bluntly.

"You’d risk his life just to buy us a few hours?"

"I would burn this entire city to the bedrock to ensure my brother’s ship reaches the open sea," I reply, my voice devoid of hesitation. "Einar knows the cost of his oaths."

I look at Freya. The rain has plastered her dark hair to her skull. She is shivering, the adrenaline of the escape fading, leaving only the cold reality of our situation.

"But stepping through this door changes the rules," I tell her, my hand resting on the iron latch. "Right now, you are a ghost. You fell from the sky. You could slip into the dark, find a hole to hide in, and wait for your magic to pull you back to your ‘future.’ If you walk away now, Gunnar’s men will not look twice at you. You are nothing to them."

Freya looks at the dark, winding alley leading away from the forge. Freedom. Anonymity. A chance to preserve her precious history without the anchor of my doomed life dragging her down.

"But if you step inside with me," I continue, my gaze locking onto hers, "you become my accomplice. You declare war on Jarl Gunnar. You tie your fate to a woman who is already dead by the laws of this city."

The sounds of the hunt are getting louder. The rhythmic thud of boots splashing through mud. The harsh, guttural barks of the tracking hounds catching a scent. They are two streets over, closing fast.

I do not open the door. I leave the latch closed.

"I cannot carry dead weight, Freya," I say quietly. "If you are going to flinch every time a piece of glass breaks, you will get us both killed. Choose. Walk away, or break your history with me."

Freya looks at the iron latch. She looks at her scarred hand, the physical proof of our shared trauma. Then, she looks up at the smoke rising from the burning market—the market she inadvertently set on fire. The history she has already broken.

The hounds howl, much closer now.

Freya steps past me. She reaches out, her hand covering mine on the cold iron latch. Her grip is surprisingly strong, the soft skin of an academic giving way to a desperate, unyielding resolve.

"Open the door," she says.

I press the iron bar down. We step into the heat of the forge, and the heavy oak door slams shut behind us, sealing us inside the dark.
