Read Chapter 27: The True Key

The blast threw Iona against the stone wall of the library. Dust and shattered mortar filled her lungs as she coughed, ears ringing, the world tilting sideways. The hearth where she had been mixing herbs had erupted outward, and in its place gaped a dark opening—a steep stone staircase descending into blackness.

Lachlan was beside her before she could blink, his hand on her arm, his face pale and strained. He had been too weak to stand a moment ago, but adrenaline had moved him. "Iona. Are you hurt?"

"I'm fine." She shook her head, tasting grit. "The locket—"

It lay on the floor, still warm, its face split cleanly along a seam she had never noticed. The silver casing had opened like a bloom revealing its center: a complex brass mechanism, gears and pins arranged in a pattern that matched the stonework of the hearth. The explosion had not destroyed it. The explosion had been the lock disengaging.

She crawled to the edge of the opening and peered down. Cold air breathed up from the stairwell, carrying the smell of old earth and iron. Faintly, impossibly, she heard water running somewhere far below.

"What have you done?" Lachlan's voice was hoarse. He was staring past her, at the stairs, and for the first time since the chapel she saw something other than pain in his eyes—something like wonder.

"I didn't know," she said. "I was following the ritual steps. The locket was supposed to be the anchor. It just... opened."

Duncan's boots thundered in the corridor. He burst through the door, shotgun in hand, chest heaving. "What the hell was that? The roof came down over the east wing—" He stopped at the sight of the gaping hearth, the open stairwell. "Jesus. The crypts. They're real."

Iona looked between the brothers. "You knew there was a vault?"

"I knew there was a rumor," Duncan said, lowering the weapon. "Our grandmother used to say the real treasure wasn't in the house above ground. She said the Blackwood fortune was buried where the moon never shines."

Lachlan swayed on his feet. Iona caught him by the elbow. He was burning up again—the fever that had crept through his blood since the failed transfer ritual was tightening its grip. His face was slick with sweat in the candlelight.

"You need to rest," she said.

"There's no time for rest." He nodded at the stairwell. "Whatever is down there, it's been sealed since before my father was born. If it's a way to stop this—"

"Then it'll still be there in ten minutes while I get you stable." She turned to Duncan. "Help me get him seated. And bring lanterns. Strong ones. We're going down."

The stairs descended deeper than any cellar Iona had ever seen. Forty steps took them past the foundation line; sixty more and the air grew heavy with the pressure of depth, the stone walls weeping with condensation. Duncan led with a gas lantern held high, and Iona followed with an arm looped around Lachlan's waist. He leaned on her more than he would ever admit, his breathing ragged but his jaw set with stubborn pride.

At the bottom, the stairwell opened into a chamber that made her stop in her tracks.

The ceiling arched twenty feet overhead, supported by carved pillars depicting wolves in various states of change—some running on four legs, others standing half-upright, others fully human with wolf heads resting on their shoulders like mantles. The carvings were old. Older than the house. Older than maybe the village itself.

Shelves lined the far walls, crammed with leather-bound books and rolled parchments and wooden boxes sealed with wax. In the center of the chamber stood a stone table. On it rested a steel chest, unrusted despite the damp, its surface etched with the same interlocking knotwork that decorated the locket.

"The hoard," Duncan breathed. "Mother always said it was a myth."

Lachlan detached himself from Iona and walked to the table. His hand trembled as he touched the chest, and Iona saw the wolf flicker behind his eyes—the golden edge of his iris catching the lantern light. He didn't lift the lid. He just stood there, chest heaving, as if the effort of resisting the change was consuming him from inside.

Iona joined him. She eased the lid open.

Inside were documents. Hundreds of them, bundled with twine and labeled in a precise, old-fashioned hand. She lifted the top bundle carefully and read the title page: *Charter of the Highland Guardians, Signed at Moira's Stones, 1407.*

She laid it flat on the table and began reading aloud. The document described an alliance of seven pack families who had sworn to protect the Highland villages from "the beasts that walk dark and the men who command them." They were not predators, the charter said. They were shepherds. They took the wolf's blood willingly to guard the boundary against what lay beyond.

"Guardians," she murmured. "Your family didn't just live here. You protected these lands."

Lachlan nodded slowly. "That's the story my grandmother told. I thought it was romantic embellishment."

"It's the truth." She found another bundle, this one newer—dated 1711. A royal decree stamped with the seal of a long-dead Scottish king. It officially recognized the Blackwood pack as the "wardens of the eastern march," granting them authority over the moors and forests in exchange for their service.

But then she reached a third document, and her blood went cold.

*Dismissal and Exile of the Ross Branch, 1779.* A dozen pages, written in the same precise hand. Iona read quickly, and the world rearranged itself around her.

The Rosses had not been a rival family stretching back to the old times. They had been *part* of the Blackwood pack—a younger branch, soldiers in the same war. But in 1778, a Ross elder named Callum had discovered a way to draw power from human blood to suppress the wolf's hold. He had taken control of a nearby village's council through fear and force, bending the villagers to his will. The Blackwoods had discovered his scheme and voted to expel the entire Ross line. Callum had fled with his followers, cursing the Blackwoods as tyrants who had forgotten their true nature.

"He wasn't exiled for a blood feud," Iona said slowly. "He was exiled for enslaving humans. The Blackwoods guard the region *against* people like him."

Duncan's face had gone stony. "And for two hundred years, they've been trying to take back what they think they're owed."

"It's not the land they want." Lachlan's voice was distant, almost dreamy. "It's the vault. The knowledge. They want to complete what Callum started."

Iona's hands moved faster through the bundles. Records, charters, correspondence—and then, at the very bottom of the chest, a slender volume wrapped in oilcloth. It bore no title, but the first page was dated 1780, the year after the exile, and written in a woman's hand.

She read three pages before the tears blurred her vision.

*The Clean Blood, or, A Treatise on the Reduction of the Curse.* It was a recipe. Herbs, minerals, precise timings tied to the lunar cycle. A way to build the mortal blood's resistance to the wolf, weakening the hold of the change without destroying it. The writer—a Blackwood healer named Morag—had developed it for her own daughter, whose wolf had consumed her will entirely.

"This is it," Iona whispered. "This is the cure."

Lachlan turned to look at her, and the desperate hope in his eyes nearly broke her open. "It can stop the change?"

"It can give you control. It won't remove your nature. But you'll be able to choose when to turn, not be ruled by the moon."

"Hell," Duncan said. "That's the whole battle right there."

Iona grabbed the book and several bundles of herbs from her pack. Her hands worked fast, grinding the roots and leaves into the iron pot she had brought down from the library. Water from the spring that trickled along the chamber's far wall, lit by the lanterns' glow. The recipe called for patience—an hour of gentle simmering—and she gave it everything she had while the brothers watched in silence.

When the potion was done, it was dark amber and smelled of heather and bitter earth. She poured it into a horn cup and held it out to Lachlan.

He took it without hesitation. Drank it in three long swallows.

For a long moment, nothing happened. He stood still, eyes closed, fist pressed to his sternum. Iona counted her heartbeats. Ten. Twenty.

Then his breathing changed—slowed, deepened. The sheen of fever sweat on his brow began to recede. His jaw unclenched, and his eyes opened to meet hers, clear and human and fully present.

"I can feel it," he said, wonder thickening his voice. "The wolf. It's there, but it's... quiet. Like it's waiting for my word instead of giving orders."

Duncan clapped his brother on the shoulder with enough force to stagger a horse. "You look like you could stand a night watch without collapsing."

"I feel like I could run the moors." Lachlan caught Iona's hand. His grip was warm and steady. "You did this."

She didn't correct him. The potion was only part of it. The vault's knowledge had given her the path.

She looked back at the chest. At the charter of guardianship, and the decree, and the recipe that could change everything.

"Meghan wants to drag you into another war," she said slowly, the pieces clicking into place. "She wants the locket because she thinks it's a weapon—something to wield against you. But it was never a weapon. It was a key. This whole estate is built over the truth of what your family was."

"The truth never mattered to the Rosses," Duncan said. "Power does."

"Then we invite them to see the truth." Iona turned to face Lachlan fully. "The locket's power isn't meant for fighting. It's meant for showing—what we were, what we could be again. If the Rosses see that the Blackwoods were guardians, not conquerors, maybe the feud ends here. In the vault that unlocks everything."

Lachlan looked at the locket, still open in her hand, its brass heart gleaming in the lantern light.

"If this is the key to all of it," he said slowly, "then it was never meant to be kept in one family's hands."

"Then we share it," Iona said. "All of it. The history, the cure, the truth. We stop hiding."

He was silent for a long moment. Then he nodded.

"The Rosses aren't the only ones who've been kept in the dark." Lachlan's voice was quiet, but certain. "The village deserves to know what the Blackwoods were. And what we want to be again."
