My Scumbag System Chapter 720: The Marrow Hum

I woke up wrong.

Not wrong like cracked ribs or dried blood on a pillowcase. Not wrong like the time Maki electrocuted the toaster and the whole kitchen smelled like ozone for three days. This was different. This was a frequency I could not name, a low hum in the marrow of my bones that had not been there when I fell asleep.

The ceiling of my room at Onyx House stared back at me. Same water stain shaped like a deformed rabbit. Same crack running from the light fixture to the corner where Bartholomew’s terrarium sat. Same immortal snail making his morning pilgrimage across the glass, lettuce leaf clamped in his tiny mouth with the conviction of a man carrying nuclear launch codes.

Everything looked normal.

Everything felt like a lie.

I sat up and the room tilted. Not physically. The walls stayed where walls belonged. The floor maintained its commitment to horizontal existence. But the space between objects had acquired a texture I could not ignore. Like someone had turned up the resolution on reality by two percent and forgotten to tell me. The dust motes hanging in the morning sunlight did not just float. They traced paths. Invisible highways of air current and thermal drift that my brain now insisted on mapping in real time.

The pendant against my chest pulsed cold. Natalia’s heartbeat. Three rooms away, sleeping on her left side, one leg over the blanket. I should not have known the leg detail. I did anyway.

"Nel."

Silence.

"Nel, wake up. Something is off."

More silence. Then a yawn that existed only inside my skull.

"I’m serious. Something changed."

I pressed my palm flat against the mattress and felt the cotton, the springs beneath it, the wooden frame beneath that, and beneath the frame the floorboards and beneath the floorboards the joists and beneath the joists the stone foundation of Onyx House sinking its teeth into the volcanic rock of the Atoll. I felt all of it. Layer after layer like pages in a book made of building materials. The sensation lasted one second and then disappeared as if a faucet had been shut.

I stared at my hand.

"That. That thing. I just felt the entire foundation of the building through a mattress."

Helpful. Incredibly helpful. Thanks, Nel.

I swung my legs off the bed and my bare feet hit cold floor. The room temperature was sixty-eight degrees. I should not have known the exact number. My skin told me anyway. Maki lay curled at the foot of the bed in cat form, both tails wrapped around her body, one ear twitching in whatever dream her three-hundred-year-old brain had conjured. She smelled like ozone and the expensive shampoo she stole from Natalia’s bathroom.

I stood. My body felt heavier. Not weaker. The opposite. Like someone had increased the density of my muscles overnight, packing more mass into the same frame without changing the dimensions. When I rolled my shoulders, something popped deep in the joint and the sound was louder than it should have been. Crisper. The echo bounced off the walls and I tracked it without meaning to.

Five rooms away, Emi turned over in her sleep. Six rooms away, Skylar’s heartbeat maintained its slow steady drum. Two floors below, Raphael’s fists hit a heavy bag in the basement gym. The impacts came every 1.3 seconds. He was angry. Raphael was always angry at five forty-seven in the morning but the intervals between strikes told me the anger had a different flavor today. More focused.

I grabbed the edge of my dresser.

None of this should be possible. Not the temperature readings through bare skin. Not the heartbeats through walls. Not the ability to determine a man’s emotional state from the cadence of his punching.

The integration had changed me. I knew that. I felt that. The partial connection to trans-dimensional energy had rewired something fundamental in the way I processed sensory input. But last night when I fell asleep, the new abilities had been faint. Background noise. Whispers at the edge of perception that required concentration to access.

This morning they screamed.

Something had shifted while I slept. Something had clicked into place like the last tumbler in a lock, and the door it opened led somewhere I could not see.

The pendant burned cold against my sternum. Natalia stirred. Through the bond I felt her consciousness rise toward waking, drawn by my own unease bleeding through the connection we shared. Her awareness brushed against mine like frost on a windowpane and I shoved the feeling down hard. She needed sleep. She had earned sleep. Whatever this was, I could figure it out without dragging Natalia Kuzmina out of bed at five forty-seven to diagnose my new and improved freak status.

Bartholomew reached the top of his terrarium and paused. The snail turned. Which should have been unremarkable because snails turn all the time. Bartholomew turned specifically to look at me with his tiny stalked eyes and held the gaze for three seconds before resuming his lettuce operation.

"Did you just judge me?"

The snail offered no comment. Immortal beings did not concern themselves with the neuroses of their mortal roommates.

I pulled on a pair of sweatpants and grabbed a shirt from the chair where Maki had not yet stolen it. The Dragon Witch’s Ring sat on my nightstand. When I picked it up, the obsidian surface flared warm against my fingers. Not the usual low hum of stored fire. This was responsive. The ring read my elevated heart rate and adjusted its output accordingly, feeding heat into my bloodstream like an attentive nurse checking a patient’s IV drip.

That was new too.

I slid the ring onto my finger and felt the fire settle into my mana channels with more smoothness than before the integration. The energy distribution had improved. Circuits that previously ran at seventy percent capacity now carried current without friction or loss. The Dragon Witch’s Ring had not changed. I had.

My bat leaned against the wall beside the door. I grabbed it and the weight registered differently in my palm. Lighter. Or rather, I was stronger. The grip tape still bore the accumulated evidence of everything the bat had done since I woke up in this body. Ichor stains from a Necropolis ghoul. Scorch marks from the Arborist. A dent from Julian Valerius’s face.

Good memories. Violent memories. The best kind.

I opened my door and stepped into the hallway.

The house breathed around me. That was the only way to describe it. Onyx House at five in the morning was a living organism of creaking wood, settling foundations, and the ambient noise of seventeen people sleeping in various states of consciousness. I heard it all. Juan’s snoring from the first floor. Jaime muttering something about protein synthesis in his sleep. Isabelle’s alarm clock ticking with mechanical patience. The soft green glow from Emi’s room where her healing aura leaked beneath the door and painted the hallway carpet in faint luminescence.

I made it three steps toward the stairs before a door opened behind me.

"You’re up."
