Shizuku noticed his expression first.
She had the specific attentiveness of someone who had spent enough time around a person to read the quiet shifts in how they looked at things, and what she read now was concern operating at low volume, contained and undisplayed but present.
"What?" she said.
Liam reached out and touched her cheek. The fur there was fine and dense, red-orange, growing in a direction that followed the grain of the underlying skin. He had not noticed it start. It had arrived with the gradual certainty of weather.
Shizuku raised her own hand and touched the same spot. Her expression crossed through something between surprise and curiosity, landing on neither.
"Is it similar to what happened to Aria?"
"Hers was grey-white," Liam said. "This is clearly a different species."
She pressed her fingertips against her cheek and considered this. "I don't feel anything unusual. No strange current, no sensation of changing. If you hadn't touched it I wouldn't have known."
She activated Ten.
The aura settled around her body in a smooth, complete shell, clean and even, the technique of someone who had practiced it long enough to stop thinking about it. The fur on her face stopped growing. The edges of it held their position and went still.
"Can you feel the power that was running through Aria's body?" Liam asked. "The thing that was working below the level of her technique?"
"No," Shizuku said. She was not uncertain about this. She looked at him. "Can you?"
"Since we stepped onto the shore."
"And the fog," she said. "What color is it to you?"
Liam looked at the air around them, the saturated red that pressed in from every direction, the visibility reduced to a narrow radius of blood-tinted murk with no shadows and no clear sky.
"Red," he said. "Deep red. Like the light is coming through something thick."
Shizuku looked at the same air.
"White fog," she said, simply. "The same as it was from the boat. Dense but ordinary." She paused. "You're the only one who sees the red."
Liam filed this away. The island was producing a transformation effect on organic matter. The effect operated on Shizuku and Aria at the biological level without their awareness. He could feel it from the outside, as a pressure, a current with direction and intent. And the color of the atmosphere was visible only to him, which meant that either he was perceiving something real that others were not equipped to detect, or the island was responding to whatever he was in a way that did not apply to the others.
Neither option was particularly comfortable.
He was also not particularly concerned, which he recognized as a response worth monitoring. The correct reaction to standing inside an island that was actively transforming people into animals while visible only to him as a blood-red environment was probably not quiet professional interest.
He took Shizuku's hand.
"There was something I didn't finish checking before Aria's situation required attention. Over here."
The black shape he had sensed from the shore resolved, as they approached, into a stone tablet. Freestanding, roughly rectangular, enormous: ten meters across and perhaps sixteen high, sunk deep enough into the island's substrate that it gave the impression of having grown there rather than been placed. The face of it was covered entirely in runes, dense and close-set, carved into the stone with a precision that the age of the thing should not have permitted.
Liam stood in front of it and looked.
He had spent most of the past year learning everything the Hunter Association's internal research archives had to say about divine script. The patterns, the inscription logic, the structural rules that governed how runes combined into functional Nen tools. He knew the standard forms. He could identify the major schools of inscription by their characteristic spacing and the way they handled corner transitions.
None of that was useful here.
The runes on the tablet were related to divine script in the way that a root is related to a branch. The underlying geometry was recognizable, the same fundamental shapes, the same quality of intent compressed into mark. But the specific forms were different. The combination logic was different. There were symbols he had not seen in any document, in any reference, in any inscription anywhere in the known world.
He was reading something that predated the tradition he had been studying.
On the boat, through the borrowed body of Aria, he was watching Linnie's back.
"Is this connected to the Dark Continent?" he asked, through Aria's mouth. "Not similar. The same environment?"
Linnie did not turn around.
"Not connected," she said. "Similar. But harsher than the Dark Continent coastline was fifty years ago. Harsher than it was ten years ago. Harsher than it was when the gatekeeper first arrived here. The direction of change is consistent." She was quiet for a moment. "Different people resist the environment differently. Netero and I are not the same. Those who could tolerate it forty years ago might not be able to tolerate it now."
Aria's voice said, "You, Netero, Pariston, and the others who went on the expedition didn't have any mutations."
A pause.
"We were at the shore," Linnie said. "We can say that about our expedition honestly: we saw the edge of the Dark Continent. We did not see the interior. We cannot make conclusions about what the interior is or what it does to people." She looked at the fog lying over the water. "The place in front of you, which I am calling extremely harsh, may be an ordinary landscape by Dark Continent interior standards. We are frogs in a well, calling the well the world."
"That's not pessimism," he said. "That's just the shape of the situation."
"Perhaps." She turned, and her old eyes found the point in the fog that was not quite looking at Aria, that was looking past Aria to wherever Liam actually was. "This corner of existence," she said, "is surrounded by endless dark. Endless unknowns. Endless things that could kill you before you understood what they were. You spend any time thinking about the actual scale of it and then come back and tell me if you haven't been afraid."
Liam considered the scale of it. He had, in fact, spent time thinking about it.
"Luck for certain," he agreed. "As for whether it was coincidence, I genuinely cannot say."
He released Aria's possession, let her consciousness return to its own steering, and brought himself fully back to the island.
Shizuku.
He turned.
Her face had continued while he had been split between bodies. The red fur had resumed growing the moment her Ten had relaxed, and it had not stopped at the cheeks and neck. It covered her forehead now. Her hair had shifted, the original dark color giving way to red-orange at the roots and spreading outward. Her eyes had not changed yet but her pupils were narrowing slowly, the shape rounding at the edges and then elongating into something that would be, in another few minutes, vertical.
She looked at him with the narrowed, pointed attention of a creature deciding what something was.
"My teeth," she said, carefully, "feel strange."
He looked at her mouth. The jaw had extended slightly. Not dramatically yet, but the direction was clear.
"Fox," he said. "Red fox, definitely. Nothing like Aria's situation."
Shizuku reached up and touched her own face, found the snout she hadn't been aware was forming, and said "oh" in a tone of genuine discovery.
He held both her shoulders and felt through the Star Mark, following the connection inward toward the source of the change. The transformation energy was running through her body the same way it had been in Aria, that current below the aura level, that thing that felt like instinct operating before thought. He could feel it clearly. He could feel the shape of it.
He drew it out.
Not violently. He did not know the mechanism well enough for violence to be safe. He approached it the way he approached most things he did not fully understand, carefully, following what he could sense, pulling the current toward the Star Mark's connection point and then through it, into himself. The energy moved. It resisted, then moved again, following the pressure he applied, filtering through the mark and into him and settling somewhere that was not quite his aura and not quite his body and not in a location he could precisely identify.
Shizuku's snout retracted. The fur on her forehead shortened and disappeared, the color retreating back through her hair. Her pupils rounded. Her shoulders dropped slightly, the tension of whatever the transformation had been doing to her muscle structure releasing at once.
She looked at him, back to herself, and then looked at his shoulder.
Her expression was the kind that does not speak immediately.
He looked down.
From his right shoulder, just below the joint, a new arm was growing.
It was his arm, structurally. The same proportions, the same skin, small enough that it had clearly started recently. It moved when he thought about moving it, which was unexpected. He flexed the new fingers experimentally. They responded.
He looked back up at the fog.
In the blood-red murk, at a distance he could not easily estimate, a shape was moving toward them. Not fast. Not slow. Moving with the specific, unhurried confidence of something that lived here and had no reason to approach at any speed other than the one it had chosen.
A figure. Getting closer.
