Read Chapter 27: The Vault's Location

Margaux worked by candlelight at Élodie’s stripped-down desk, her breath fogging in the February chill. The locket lay open between them, its twin halves gleaming with a fresh layer of silver filigree that pulsed faintly, like a heartbeat caught in metal.

“The spell is memory-infused,” Margaux said, not looking up from her work. Her wand moved in tight, precise circles over the broken hinge. “It remembers the shape of what it was meant to hold. Your grandmother’s magic was keyed to blood, but this repair is keyed to intent.”

Élodie sat on the edge of her bed, knees drawn to her chin. The dormitory felt smaller now, emptier, the walls stripped of her posters and photographs by order of the disciplinary board. Only Margaux’s presence kept the room from feeling like a cell.

“Intent,” Élodie repeated. “Whose intent?”

Margaux finally looked up. Her face was pale, shadows carved beneath her eyes. She’d been helping Élodie for three nights straight, sneaking past curfew, lying to her own housemaster about where she was going. The strain showed.

“Yours. What you want the locket to do.” She set down her wand and held the locket up. Light caught the repaired hinge, and for a moment Élodie saw her own reflection in the polished silver—young, tired, desperate. “Try it now.”

Élodie took the locket. Its weight was familiar, warm from Margaux’s handling. She turned it over, tracing the engraved symbol on its face—the same symbol that had been slipped under her door, summoning her to the clock tower.

But she wasn’t going to the clock tower. Not yet.

Bastien had told her the vault was hidden in the old observatory, sealed behind blood and memory magic. The locket was the key. But the observatory had been condemned for decades, its doors boarded shut, its domed roof crumbling into the gardens below. If the vault was there, it had been forgotten by everyone except Veritas.

“What do I want it to do?” Élodie whispered.

The locket grew warm in her palm. The symbol on its face shimmered, then shifted—rotating slightly, like a compass needle finding north.

Margaux inhaled sharply. “Where is it pointing?”

Élodie looked down. The symbol hadn’t just shifted. It had rearranged itself into a pattern she recognized from Bastien’s map—the path through the Catacombs Club’s tunnels, the one that led beneath the university grounds toward the abandoned observatory wing.

“It’s showing me the way,” she said.

The observatory was harder to reach than Bastien had implied. The Catacombs Club’s tunnels were safe—their members had mapped every stone, every cistern, every collapsed passage—but the final stretch required climbing through a rusted maintenance shaft that opened into the observatory’s basement.

Élodie emerged covered in dust and cobwebs, her hands scraped raw from the climb. Margaux followed a moment later, dropping to the floor with a muffled curse.

“If I die down here,” Margaux muttered, brushing filth from her sleeves, “I’m haunting you.”

“If I die down here, I’m haunting you first.”

The basement was pitch black. Élodie raised her wand, but the light sputtered—her magic was still unreliable, still raw from the memory-draining ordeal in Delacroix’s office. Margaux’s wand flared brighter, casting long shadows across the walls.

The observatory had been beautiful once. Even now, Élodie could see the bones of it—the curved walls, the remnants of painted constellations fading above their heads, the brass fittings that had once held telescopes aimed at the night sky. But time and neglect had taken their toll. Water stains streaked the plaster. A tree root had punched through one wall, thick as a man’s thigh. The air smelled of mold and old paper.

“Where’s the vault?” Margaux asked.

Élodie held up the locket. It was burning hot now, the symbol on its face pulsing with a light of its own. She followed its pull across the basement, past a collapsed bookshelf, past a shattered globe of the stars, to a section of wall that looked entirely ordinary.

“Here,” she said.

Margaux examined the wall. “It’s just brick.”

“It’s not.” Élodie pressed the locket against the mortar. For a moment, nothing happened. Then the wall rippled, like the surface of a pond disturbed by a stone, and the bricks began to shift—rearranging themselves into an archway that hadn’t been there before.

Beyond the archway was a room.

It was small, circular, lined with shelves. But the shelves weren’t filled with books. They were filled with jars—glass jars, each one containing a swirling cloud of silver light. Hundreds of them. Thousands. They cast a soft, ethereal glow that made the room feel underwater.

“Memories,” Élodie breathed.

Margaux stepped closer, peering at the jars. “Whose?”

Élodie didn’t answer. She was already moving deeper into the room, drawn by something she couldn’t name. At the center of the circular space stood a single pedestal, and on the pedestal lay a book.

It was bound in dark leather, cracked with age, its pages yellowed and fragile. No title graced its cover. But when Élodie touched it, a shock ran up her arm—the unmistakable jolt of magic recognizing magic.

She opened it.

The handwriting was cramped, rushed, the ink faded to a pale brown. It was dated—not with days and months, but with events. *The day the dean accepted my dissertation. The night we first argued about the archives. The morning I discovered what she’d done.*

“Lucien’s diary,” Élodie said.

“Bastien’s ancestor?” Margaux asked.

“The founder’s brother.” Élodie turned the pages, her fingers trembling. The entries grew more agitated as she read—references to experiments, to sacrifices, to a ritual that was meant to preserve the university’s magic forever. And then, near the end:

*I have confronted her. I have shown her the evidence—the empty jar, the missing student, the blood on her hands. She did not deny it. She only smiled and said that some sacrifices are necessary for the greater good.*

*I told her I would expose her. I told her I would take the charter to the council and show them what she had become.*

*In response, she did this to me.*

The writing broke off. The next entry was barely legible, the letters smeared and uneven, as if written in great pain.

*I do not remember my own name. I do not remember my sister’s face. She has taken it all from me, the way she takes everything—my memories, my magic, my future. But I have hidden this diary where she cannot find it. I have hidden the true charter where she cannot read it.*

*If you are reading this, you are one of us. You carry the blood of the founder’s line. And you must know the truth:*

*The Dean is one of us.*

Élodie’s breath caught. She looked up at Margaux, whose face had gone very still.

“The Dean,” Margaux said slowly. “Which Dean?”

Élodie turned the page. The final entry was only two lines, written in a hand that was no longer shaky, but absolute:

*The Dean is one of us, and she is immortal. She was there at the founding. She is still there now. And she has been erasing everyone who ever discovered the truth.*

“No,” Margaux whispered. “That can’t be right. Dean Faubert has only been at the university for twenty years. Everyone knows that.”

Élodie stared at the words. The locket was cold now, its warmth gone, as if it had given her everything it had to give.

“Lucien wrote this,” she said slowly. “Before he was erased. He says the Dean’s immortal. Which means she doesn’t have to be the same person.” She swallowed. “She just has to look like one.”

Margaux’s eyes went wide. Outside the vault, deep in the university’s heart, a bell began to toll—the midnight hour, marking the beginning of the next day. The day Élodie was supposed to meet Bastien in the clock tower.

But everything had just changed.

The Dean was one of them. The Dean was *her*—the sacrifice, the ritual, the immortal who had been feeding on students for centuries. And Delacroix, the man who had been manipulating Élodie since the beginning, was her agent.

The diary trembled in Élodie’s hands.

“We have to warn Veritas,” Margaux said.

“No.” Élodie looked up, her mind racing. “They’ll think we’re lying—we don’t even know who the Dean is. Not really. No face, no name, no proof except this.” She held up the diary. “And the diary’s memory-magic is corrupted. Anyone can dismiss it.”

“Then what do we do?”

Élodie thought of Constance—the raven-spy who had stolen her sphere. Thought of Delacroix—the professor who had been playing her from the beginning. Thought of Bastien—the stranger who had shown her the truth but kept his own secrets close.

“We need the sphere,” she said finally. “Delacroix wanted it. The Dean wants it hidden. Whatever’s inside it has to be powerful enough to destroy them both.”

Margaux’s hand found hers. “Then we take it back.”

Élodie squeezed her fingers. Outside the vault, beyond the ruined observatory, the university slumbered in its ignorance. And somewhere in the dark, the immortal Dean was watching, waiting, and remembering.
