Huarti drives the curse deeper, and the dark script on the wall thickens like old blood. The hidden channel shudders, then seals into a hooked tether, making the breach answer only here.

Shadow-smoke leaks from the false door and sinks into the stone, not escaping but binding. The castle groans once, then grows still, as if it has been forced to remember its master.

Huarti twists the remaining force into a stricter knot. Any stray essence, any loosened ward, any trespasser's trace is dragged into the tether and held at the point of origin.

The overwritten ward-pattern pulses black-red across the wall, then settles into a permanent seal. The passage is no longer a wound, it is a collar, fixed to Huarti's command.

Beyond the seal, something on the far side shifts once, testing the bond. The hidden channel stays shut, but its pull is alive now, waiting for Huarti to decide what else to bind.

Huarti eases his hand from the wall, and the seal stays shut without his grip. The black-red script breathes once, then stills.

A faint silver thread unspools from the stone, then slips free, carrying only a soft, clean spark. It rises like a released breath and vanishes into the dark.

The hooked tether loosens its hold on the harmless traces, and they fall away from the castle as if remembered and forgiven. What remains is only the hostile residue, clenched tight at the far side.

The wall answers with a deep, muffled thud. Somewhere beyond it, the hidden channel strains, but nothing living is carried with the pressure now.

A few pale motes drift out through a hairline seam, then scatter. High in the gloom, a pair of guardian seagulls wheel past the broken arch and vanish.

The castle settles into a prison of its own making, the false door fixed like a collar. From inside the stone, the far side gives one last testing pulse, waiting on Huarti's next command.
