You can't cut fog.
Maximus learned it in the first ten seconds. Abyssalfang passed through the black mass and the mass closed around the blade, and the runes screamed — the sword had never screamed before — and Maximus tore it free with half the blue fire guttered out.
Then the fog touched him.
It brushed his left arm, just the edge, and the sleeve unraveled — not torn, unmade — and the skin beneath went gray. Dead. He stared at his own dead hand and couldn't feel it at all.
"Max!" Lyra was there, dragging him back, her crimson shields flaring and dying against the fog. Behind her, Kael was coming — methodical, unstoppable — and the army pressed Seraphina and Elias back step by step.
It was falling apart. All of it.
Seraphina's staff cracked — a hairline fracture up the gold — and her wall of fire guttered. Elias was on his knees, blood running from his nose, whispering bindings with no voice left. The dead kept coming.
And the fog kept growing. It filled half the chamber now, a roiling black mass shot with green, and at its heart something pulsed — a denser knot, a core. Morikk's will, concentrated.
"Brother," it said, in that grave-collapse voice. "Watch."
A tendril shot out — faster than thought — and wrapped around Lyra's throat.
Kael stopped.
Just for an instant — the green eyes flickering — the sword in his hand trembling. But the tendril tightened, and Lyra's feet left the floor, and Maximus screamed —
"HEY!"
The voice was small, and furious, and very close.
Pip hovered six inches from the fog's pulsing core, her light blazing white-hot, her tiny fists on her hips.
"Yeah, you. Foggy." She jerked a thumb at herself. "Pip. Fairy. Nightmare. You talk a big game for a fart cloud."
The fog recoiled — actually recoiled — and then surged toward her in a wall of black rage.
"Too slow!" Pip moved — a streak of light, corkscrewing through the air, and the fog chased her, tendrils lashing, missing by inches. "What's the matter? Three hundred years as a thought and you still can't catch a girl?"
She was leading it. Maximus saw it — she was curving her flight in a wide arc, drawing the mass of the fog after her, toward the center of the chamber. Toward the Heartstone.
The Heartstone pulsed. Faster now. It had noticed.
"Pip!" Maximus shouted. "Don't you dare —"
"Shut up, Max!" She barrel-rolled under a tendril, laughing — actually laughing, wild and bright. "Hey! Morikk! Your brother says hi!"
The fog roared — a sound like the world ending — and lunged, its whole mass condensing into a spear of black aimed at her heart.
Pip went straight up.
The spear missed her by a hair — and kept going, carried by its own momentum, straight toward the Heartstone.
The Heartstone reached.
It wasn't a hand. It was a pull — the air itself bending, light bending, the song underneath everything suddenly audible, a single vast note. The fog spear stopped mid-air, writhing — and then it began to unravel, threads of black and green peeling away, streaming into the crystal heart.
"NO!" Morikk's voice — raw, terrified, his for the first time. "I AM ITS CHILD — IT CANNOT —"
But it could. The Heartstone had made him. And now it was taking him back.
The fog thrashed, tore at the stone, at the air — a tendril caught Pip, yanked her toward the pull —
Maximus moved. Violet fire. He caught her wrist a heartbeat before the Heartstone took her too, and hauled — both of them tumbling across the basalt as the last of the fog streamed screaming into the crystal.
Silence.
The Heartstone pulsed — once, slow — and went dim. Sated.
Where the fog had been, the floor was gone. A chasm split the chamber, black and bottomless, its edges still glowing with violet heat.
Pip lay on the basalt, gasping, her light flickering. She looked up at Maximus. Grinned, bloody and triumphant.
"Told you," she wheezed, "I was his nightmare."
