Chapter 14: Residue

The mudflat swallowed each step with a wet suck that sounded like the ground itself was trying to hold him. Jarrin hauled his weight forward over slick clay, the deck of cards clutched in one hand, the other arm pumping out of rhythm against the sucking resistance. Every inch of it required effort. He should have been able to just walk across exposed land and be done with it, but this mud had been underwater for three hundred years and hadn't decided to behave like dry ground yet.

Behind him, the group had already settled into their positions. Fred stood near the waterline with the rolled blueprints pressed against his chest. Velma adjusted her device and scanned the mudflat for anything that registered energy. Shaggy and Scooby kept a safe distance, Scooby sneezing. Daphne was somewhere in there too, Jarrin couldn't tell where exactly, probably behind Fred.

Jazz stayed at the shoreline, and Poker Face stood ten feet out on the mud flat with her cards fanned, watching the ruins like a sentry. The gray woman's white hair was motionless in the stagnant air, and she didn't shift her stance at all.

Jarrin turned toward the mansion.

The ruins stuck out of the water like something a giant had chewed on and spat back. Foundation walls jutted at broken angles, half submerged in bayou water that pooled around their bases. The roof was gone, upper floors were gone, and what remained was mostly a concrete skeleton stripped down to its load-bearing bones. A few scattered floors still held in places, with rooms visible through gaps where walls had collapsed inward rather than outward, which meant whatever had taken them down had pulled rather than pushed.

He found the breach in the exterior wall about twenty feet from the waterline. A section of foundation had buckled at an angle that created a gap wide enough to squeeze through, where concrete had fractured along a rebar seam and the jagged edge leaned inward like a broken jaw. The gap sat half underwater. Jarrin knelt in the mud, tested the temperature of the water pooling against the fractured edge, and decided it wasn't deep enough to drown him if he just crawled.

He went in on his stomach and dragged himself through. The concrete edge scraped his shoulder. Bayou water poured into the opening and splashed up around his back, and he had to hold his breath for a second as it flooded his nostrils. The interior opened up into a room he couldn't identify, probably a hallway based on how long it stretched before something blocked his view.

The water inside had receded enough to expose most of the floor, though it still lapped at the base of the lowest steps along one wall. The room was roughly fifteen feet across, with water pooling in the lowest depression, and the load-bearing walls stood straight and true on both sides. Whatever had taken out the rest of the mansion had preserved this space. The walls showed cracks, but the structure held.

Jarrin stood up. Water dripped from his shirt. His shoes squelched.

He waded forward.

The room ahead of him was bigger, possibly a lobby or a main corridor, with a ceiling that still had ornamental plaster molding running along its edge. Fallen beams lay across the floor, partially submerged, and a desk or some kind of furniture sat on its side in the center of the room with water lapping around its base. The marble floor was slick with algae and bayou sediment, and his bare feet, already raw from the walk across the mudflat, slipped sideways on every step. He moved like someone walking on wet ice who had decided that dignity was a lower priority than getting to the other side alive.

The walls were different here. Faint traces of something silver ran through the plaster, like veins of metal embedded in the surface, pulsing in patterns that were too slow to be electrical and too rhythmic to be mechanical. Jarrin stopped and turned sideways so he could see the wall better. The silver traces were barely visible, just a faint shimmer against the gray plaster that made his eyes water if he stared too long.

Pryce had looked like this. The same silver light had run through his skin when it consumed him, threading through bone and muscle until his body had gone translucent. These traces were the same energy, just diluted. Filtered through the mansion's architecture over years or decades until only residue remained.

He kept moving. The silver traces thickened as he went deeper, growing from faint shimmers into visible lines that branched across walls and ceilings in patterns that reminded him of nerve pathways or electrical diagrams. The energy wasn't active. It didn't pulse or move on its own, but when Jarrin passed close enough, the traces would brighten by a fraction, responding to his proximity as though the mansion's dead architecture still recognized Stand energy and wanted more.

The interior spread out ahead of him in a configuration that didn't match any floor plan he'd seen. Corridors forked at angles that shouldn't exist, and doorways opened into rooms that were clearly too large for whatever they were supposed to be, with ceilings high enough to hold a grand hall but walls built for a narrow study. The mansion had been rewritten during its collapse, with dormant Stand energy still actively reshaping the structure from within. The geometry was wrong. Jarrin could feel it in his balance, in how the floor seemed to tilt a fraction off horizontal without actually tilting at all.

He reached a wall where the silver residue was thickest. The lines ran vertically in a dense cluster, branching into finer traceries that covered the surface like frost on glass. This was where the energy concentration was highest, the spot that Fred and Jazz would want to draw from first.

Jarrin placed his right hand against the wall.

The moment his skin touched the residue, the silver lines flared. A jolt traveled through his palm and up his arm like a static discharge, sharp and hot, and the residue didn't absorb into his skin. It recoiled. The silver traces pulled back from his touch like a wounded animal, retreating into the plaster with a visible hiss that sounded nothing like actual sound and everything like energy doing something it wasn't supposed to do. The residue writhed under his palm, spreading in thin threads that slid along the wall surface and refused to make contact with his skin.

Jarrin yanked his hand back. His palm tingled. The residue had fought him off, recognized him as an unauthorized conduit, and refused to be drawn.

"Jarrin!" Jazz's voice cut across the mudflat from the shoreline, sharp enough to cut through the mansion's interior noise. She'd seen enough through the breach to know something had gone wrong.

He pulled his hand fully away and stared at it. His palm looked normal, no burns, no discoloration, but the residue on the wall had pulled back three inches from the point of contact. The silver traces were still there, just concentrated further from the edge, and they pulsed faintly as they rearranged themselves into a configuration that resisted further contact.

Raw Stand energy embedded in architecture wasn't the same as absorbing a signature from a mechanism. Fred had warned about that. The dormant residue would shock a user's nervous system if drawn directly, and apparently it would actively defend itself against anything that tried to take it. Jarrin's hand hadn't been able to force a connection because the energy wasn't passive. It had a defense mechanism, or at least a rejection response, and the Poker Face cards were supposed to filter exactly that kind of hostile transfer.

He looked down at the deck in his other hand. Jazz's cards, still dry, still intact. The deck she'd shoved into his palm on the shore, and she'd been counting on this exact method to pull energy from the ruins safely.

Jarrin pulled a card from the deck. It was the Queen of Spades, back facing him, and he turned it over so the face showed. The card felt warm against his fingertips, warmer than it should have been, already absorbing ambient Stand energy from the air. He held it flat against the wall's surface, positioning the card's center over the thickest concentration of silver residue.

The moment the card touched the wall, the silver lines surged toward it. Not into his hand, not into his arm, but directly into the card's surface. The residue spread across the Queen of Spades like ink soaking into paper, filling every blank space on the card's face, and then the energy flowed backward from the card into Jarrin's body.

It hit him like a current running through his nervous system from shoulder to fingertip. His right arm seized, and for half a second he couldn't tell if the surge was coming from the card or from somewhere deeper, from his own Stand, from Jolly Roger trying to react to energy that shouldn't have been accessible to him. The filtered energy bypassed his skin, moved through the card as a conduit, and entered his body in measured portions that Poker Face had calibrated before they reached his nervous system.

A white shape flickered above his shoulder. Jolly Roger materialized for maybe two seconds, the pirate's red eyes locking onto the card with something that looked like recognition, and then the Stand dissolved back into nothing as the energy transfer completed.

The surge stopped.

Jarrin stood very still and wiggled his fingers. They moved. He flexed his hand. The motion worked, sort of. The right hand responded to his commands, but the signal arrived late, like there was a three-second delay between his intent and the muscle's response. The fingers felt thick, numb at the fingertips, like he'd been holding them underwater for hours.

His right arm was dead weight from the elbow down. Not paralyzed, not useless, but burned out. The nerve pathways had taken the energy transfer and rerouted it through channels that weren't designed to carry Stand power, and the overload had fried a section of his nervous system. The arm still moved when he willed it to move, but the responses were sluggish, the signals scrambled by something that had damaged the wiring.

He looked at his right hand again. It was pink, swollen at the knuckles, and when he tried to close it into a fist, the tendons fired late and the fingers folded at awkward angles. The burn had gone deep. Jolly Roger was gone, dormant, and trying to call it forward produced nothing but a dull ache in the damaged arm.

The mansion's interior was still shifting around him. The geometry hadn't stabilized, and the silver traces on the walls pulsed slower now, as if the transfer had drained a fraction of what remained. Jarrin turned toward the breach in the wall and began the long walk back through the flooded corridors, navigating by memory rather than direction, stepping over fallen beams and avoiding the deepest pools of water.

The breach took longer to exit than it had to enter. The water poured in from the bayou side, filling the gap, and he had to duck under a low section of wall where concrete had buckled inward. He crawled through into the afternoon light and collapsed onto the mudflat on his knees, breathing hard.

The mud sucked at his knees and the smell of bayou and old concrete filled his nose. Jarrin looked up and saw Jazz standing five feet away, Poker Face materialized beside her, both of them watching him. Jazz's expression didn't change, but she was already reaching out with her left hand to steady him.

"I need to tell you about the energy transfer--" he started, but before he could get any further, Velma's voice cut across the mudflat from twenty yards to the east.

"Everyone, here. Now. Look at this."

The group was already moving. Fred grabbed the blueprints and started walking. Daphne fell in beside him. Shaggy and Scooby followed at a less confident pace, Scooby sneezing. Jarrin hauled himself upright with Jazz's help and limped east across the mudflat, his damaged arm hanging at his side and his brain trying to process what Velma had found.

She was standing over something in the mud about thirty feet from the waterline. The group had already gathered around her, and Velma's device was pointed at whatever lay on the ground in front of her.

It was an arm. Severed at the shoulder. Left arm, which meant it came from a right-handed person or someone who had been positioned facing the wrong direction when it was taken off. The wound glistened in the daylight, the cut surface pale and wet and still fresh enough to show the layered structure of muscle and tissue beneath the skin. The forearm and hand stretched out from the stump toward the mud, and the skin was translucent. Silver lines ran through the tissue, threading through muscle and bone, threading through the hand itself until the fingers themselves carried faint traces of the same energy that had consumed Pryce.

The silver lines extended from the stump into the mud as if something still connected the arm to the rest of the mechanism beneath the waterline. Velma's device hummed steadily, its needle pinned to the active end of its arc.

"The residual energy signature is active," Velma said. "Rhythmic. Pulsing at regular intervals." She turned the device toward the arm, and the needle responded to the silver lines threading through the tissue. "Consistent with a Stand operating independently of its host. The mechanism that severed this arm is still active somewhere below the waterline. It's connected to the mansion's foundation vault, and it's sending energy through this arm as a conduit."

Fred stared at the severed limb. His blueprints dropped to his side. "Pryce's arm."

Velma nodded. "The energy signature matches what we observed in Pryce before the collapse. Whatever remains of his Stand and the mechanism beneath the island is still functional. The arm is a dead end for the energy, but the source is still sending power through it."

The group stood in silence around the severed arm. The mud flat was quiet except for the lap of shallow water against the exposed shoreline. Scooby had stopped sneezing, which meant even he understood something was wrong. The silver lines in the arm's translucent flesh pulsed faintly, slower now, like a heartbeat that had grown tired but refused to stop.
