Adventure of Tancred du Forietan

Sister Ilse lunges for the blade, her fingers shaking with panic and purpose as the vault’s cold bites deeper into the bones. Her voice cracks as she cries that the debt must be paid in full, or the house will devour them all.

Tancred keeps the blade just out of reach. The blackened names in the ledger seem to drink the amber light, and the altar answers with a low, hungry thrum.

Ilse flinches at Natasha’s smile, then reaches again, not for mercy, but for the hilt. Her eyes are wide and empty, as if she is watching something behind Tancred rather than him.

The chamber goes still for one terrible beat. Frost creeps over the carved stone, and the du Morvannoux crest glows faintly beneath Tancred’s hand, waiting for a choice the house can taste.

Tancred speaks the name into the vault, but the altar remains cold and silent. The amber light flickers and dies, leaving the chamber in a suffocating, absolute stillness.

Tancred snaps his arm across Sister Ilse's reach and drives her back from the blade. She stumbles hard against the frost-slick stone, breath catching in a thin gasp.

The room answers with a dull shiver. Frost spiders farther over the carvings, and the altar gives off a faint, fragile hum from somewhere deep in the stone.

Tancred turns with the broken ancestral blade still in hand and catches a narrow seam in the masonry, half-hidden behind the altar's shadow. Bone-white ash dusts the ledge beneath it, as if old records once rested there.

He forces the seam open. A cramped recess yields a warped iron clasp and a strip of dampened parchment, both chilled stiff with age.

As Tancred pulls the parchment free, the ember-light in the blade dips lower, and a sharp crack runs through the floor beside his boots. He has the proof and a new way to press the vault, but the jolt sends a thin split through the stone at his feet.
