The Pulse Beneath

The Pulse Beneath

We didn’t stop for days.

Or maybe hours. Time had no meaning in the ashlands. The sky never changed. Just that pale shimmer bleeding through gray, a sun that refused to rise or die. Each step sank into dust that clung like memory. The air tasted like bone ground fine and left to rot.

Evelyn walked ahead, blade drawn even when she slept. My sister followed in silence, her small hands wrapped in rags to keep from freezing. The world had gone quiet, but not dead. Things still moved under the surface slow, deliberate, patient. You could feel their breath beneath your feet.

And always, the pulse.

Soft at first. Then stronger. Like something deep below was keeping time with my heart.

I didn’t tell Evelyn. She already looked at me like I was the next threat. The burn that had once marked my arm now crawled across my collarbone, glowing faintly through the dirt and sweat. At night, I could see it in the reflection of her eyes.

She never said a word. But she saw.

On the fourth night if you could call it that we camped in the shell of what used to be a house. The roof was gone, the walls bowed. My sister slept curled between us, clutching a broken doll she’d found in the sand. Evelyn sat opposite me, sharpening her knife with slow, deliberate strokes.

“You’re changing again,” she said finally.

“Always am.”

“This isn’t like before.” Her eyes caught the faint light crawling under my skin. “That thing you took in—the pulse it’s spreading.”

“It’s keeping me alive.”

“For now,” she said. “Until it decides it doesn’t need you anymore.”

“Then I’ll cut it out.”

Evelyn laughed softly, bitter. “You said that last time, remember? When you still thought pain meant you were in control.”

I didn’t answer. She was right. Pain used to be my compass. Now it was just background noise.

I stared at the horizon. Far ahead, the ash shifted like waves, and for a moment, I thought I saw movement something vast and coiled beneath the surface. The ground trembled, faint but steady.

The pulse answered.

Evelyn felt it too. She looked up, knife frozen mid-sharpen. “Grace…”

“I know.”

We stood at the same time. The air grew heavy, thick with static. My sister stirred but didn’t wake. The trembling deepened, and from the east, the ash rose like a living wall.

The ground split open.

Something moved beneath us huge, skeletal, glimmering faintly in the dim light. The shape of a spine, endless and ancient, twisting through the dirt. Its movement created waves that rippled the sand.

Evelyn cursed under her breath. “Tell me that’s not what I think it is.”

“I don’t know what you think it is.”

“It’s the thing that made the tower. The one you woke up.”

She wasn’t wrong. The pulse inside me was screaming now, matching its rhythm perfectly. Whatever was under us it was connected. Not separate. Not alien. Part of the same body.

Part of me.

The ground cracked again. A hollow sound followed like a heart beating underwater. Evelyn grabbed my sister, dragged her toward the broken wall. “Grace! Move!”

I didn’t.

I could feel it calling. Not with words, but with rhythm. The same cadence that had guided me through every nightmare since the beginning.

I stepped closer to the fracture.

“Don’t!” Evelyn’s voice tore through the storm of ash.

Too late. The ground gave way.

The world tilted.

Then darkness.

I woke in heat.

Liquid surrounded me. Not water. Thicker. It glowed faintly red, veins of light pulsing through it. I was floating, though I couldn’t move. The pulse here was deafening. Each beat slammed through my body like thunder.

Shapes drifted in the haze around me figures half-formed, dissolving and reforming. Faces I knew. Max. Evelyn. My sister. All of them whispering through the same mouth.

You brought it back.

I tried to speak, but no sound left me.

You fed it with every wound. Every time you cut the world to stay alive. You called it, Grace. You became its vessel.

The heat burned through my skin, searing into bone. The pulse wasn’t just sound now it was motion. It was thought. I could feel it wrapping around my heart, squeezing in time with every beat.

“I didn’t mean to,” I whispered.

You never do. That’s why it chose you.

The light brightened. The liquid began to churn, dragging me downward. For a moment, I saw the creature’s reflection in the surface above a shape made of ash and flame, the same one I’d consumed. It smiled.

Then it pulled me under.

I fell into another chamber open, cavernous, glowing faint gold. The floor pulsed beneath my feet like flesh. At its center stood a column of light stretching upward into darkness. The sound of breathing filled the space slow, monstrous, endless.

Evelyn’s voice cut through the echo. “Grace!”

She was there barely standing, covered in ash and blood, clutching my sister in one arm. Her eyes were wide, reflecting the column’s glow. “What did you do?”

“I didn’t jump,” I said. “I fell.”

“That’s not an answer.”

“No,” I said, “it’s not.”

The light swelled. From its center, something emerged humanoid at first, then shifting, expanding. A figure made of the same white fire that lived inside me. Its features flickered through faces I recognized. Mine. Max’s. Evelyn’s. Then none.

When it spoke, it used my voice.

You were never separate. You were always the echo. The surface reflection of something buried deeper.

Evelyn raised her knife. “Get behind me.”

The figure laughed a dry, hollow sound that made the walls shudder. She can’t protect you. She never could. You built her too.

Evelyn froze. “What?”

The figure looked at her. Its eyes were voids of light. She’s the shape of your guilt. The blade you gave yourself to keep from cutting your throat.

“That’s not true,” Evelyn whispered.

“Maybe it is,” I said quietly.

Evelyn turned to me, eyes wide. “Don’t start believing its lies.”

“They’re not lies if they fit,” I said.

The figure smiled. Good. You’re learning.

It reached toward me. The glow wrapped around my shoulders, pulling me forward. Evelyn lunged, stabbing through the light, but her blade passed clean through. The heat scorched her arm. She screamed, fell to her knees.

The figure leaned close. Its voice was inside my skull again. Stop fighting what you are. You can end it all. One heartbeat. One release. Let the world dissolve into the rhythm. Peace at last.

My heart stuttered. The pulse surged.

For one moment, I wanted it. The quiet. The end.

Then I saw my sister’s face tiny, terrified, still clutching the broken doll. Evelyn bleeding, still trying to stand even when she couldn’t.

I closed my eyes. “No.”

The light flared white-hot. The ground convulsed.

You can’t deny me, it hissed.

“Watch me.”

I plunged my hand into the glow, gripping the rhythm itself the heartbeat of everything wrong inside me. It felt alive, thrashing, desperate to be free. I dragged it out, screaming through clenched teeth, and for a second I thought it would take me with it.

Then it broke.

Silence.

The light vanished. The pulse stopped.

When I opened my eyes, the cavern was gone. I was lying on cold ash again. Evelyn was beside me, breathing shallow but alive. My sister knelt over us, tears cutting clean tracks down her soot-covered face.

“Grace?” she whispered.

“I’m here.”

The pulse was gone.

For the first time since this all began, the world was quiet.

Evelyn sat up, staring at me like she didn’t believe it. “You killed it?”

“No,” I said. “I just stopped listening.”

The horizon flickered faintly, like a dying ember. The air smelled of rain not the real kind, but memory. My arm no longer glowed. The burns had faded to faint scars. The silence wasn’t peaceful, but it was mine.

Evelyn touched my shoulder. “What now?”

“Now?” I looked at the horizon. “We see if the world remembers how to live without the pulse.”

She smiled weakly. “And if it doesn’t?”

“Then I’ll teach it.”

The wind shifted, carrying the scent of distant thunder. My sister took my hand, small and warm. Evelyn sheathed her blade.

For the first time in forever, I felt something almost human hope’s ghost, faint and trembling. It wasn’t enough to save us. But it was enough to walk again.

And so we did.

Through ash.

Through silence.

Toward whatever heartbeat waited next.
