The Obsidian Guild headquarters did not advertise itself.

The structure had been carved into the interior of an old volcanic rise, the stone black and polished to a muted sheen. Windows were narrow and deliberate, admitting light in measured slices that never quite reached the floor. Nothing here was decorative. Everything served a purpose.

Elias Rowe preferred it that way.

He sat at his desk reviewing the Guild's quarterly ledgers, a slim stylus moving with careful precision across the page as he annotated dividend distributions.

The ledger did not track only trade and dividends.

Several columns carried names instead of merchants. Each marked with a small black symbol Elias had added over the years.

Nyxara's name appeared on one of them.

A knock sounded at the inner threshold.

Elias finished the line he was writing before he spoke.

"Enter."

The door opened quietly.

A man stepped inside, travel-worn gray cloak still dusted with the grit of the eastern roads. His hood was lowered, but his face remained the sort that refused to linger in memory. Even the eye struggled to hold it for long.

The posture beneath it was unmistakable—straight-backed, measured. Warden-trained.

Vael Corren had not stood among them in years.

He stopped short of the desk. "I have news."

Elias set the stylus down parallel to the ledger's edge before leaning back. "Go on."

"Blackvein made it to Stillreach and has reached the Axiom Heart."

A hint of a smile touched his dull red lips. "Of course she did."

Elias rose from his chair and crossed to a large stone table in the center of the office. Upon it rested a scale model of Stillreach. Every district had been carved with obsessive accuracy. Concentric rings of streets spread outward from the Stoneward Circle tower at the center. Even the water channels had been etched into the terrain.

He rotated the miniature tower a fraction, aligning it with the etched channels that spiraled outward through the districts.

Stillreach was not the only city represented on the massive table.

Models of other cities surrounded it—some finished, others only half-carved.

Elias slid one of the small crystal rods from the model's base and inserted it into the tower's core.

The miniature shimmered faintly.

A low pulse traveled up through the crystal and into his fingers—precise, measured. Elias held it there a moment longer before releasing it.

"She didn't remove the Axiom Heart when she had the chance," Corren added carefully.

"Why not?"

Corren clasped his hands behind his back. "Unknown. According to my man, the Wardens know she carries the Mark."

"A clash of blades perhaps?"

"Possible. But..."

"Go on."

"Blackvein has aligned herself with someone," Corren said at last.

Elias's hand paused over the model, the tension held so precisely it barely showed. He let the silence stretch before responding. "Name?"

"Torin Cross."

"One of the Meridian Authority's pawns," Elias said, the words flattening. "They will try to make it something it isn't."

"And the Guild?" Corren asked.

Elias tapped the tower with one finger.

"Stillreach demonstrates only partial awakening," he said. "Shield projection. Environmental stabilization. Limited geomantic correction."

His attention shifted, not to the model, but beyond it—to a narrow shelf near the stone wall. Several pages of parchment rested there, their edges torn ragged where they had been removed from an old book in Stoneward Circles tower.

"The Wardens preserve what they understand," Elias said. "And ignore what they do not."

On one of the pages, a single line stood out:

The Axiom Heart, also called the Ember Stone, is star-fall architecture.

Elias adjusted the central rod a fraction.

"The Wardens are outdated."

His gaze settled on Corren. "You know that better than most."

Corren nodded. "It's why I came when you asked."

The crystal's glow dimmed as Elias stepped back.

"With my guidance," Elias said, "it will restructure the world."

Silence settled in the room.

Corren finally asked the question that had lingered between them.

"And Blackvein?"

Elias traced the outer ring of the city with one finger.

"Nyxara Blackvein's parents refused my request to infiltrate Stillreach. They were executed for their lack of vision."

Corren's gaze dropped to the edge of the table.

"Nyxara's potential was recognized long before she ever knew we were watching. And now, she is one of my finest," Elias said.

He steadied the central rod without looking, this one darker than the first.

"She was engineered for loyalty."

"She believes the Mark was an attack. Not a gift," Corren said quietly.

Elias nodded slowly. "If she learns I ordered you to give her the Mark, she will try to kill us both."

Corren had not looked away.

"But she was never meant to remain in Stillreach," Elias continued. "She was meant to crack it open."

He realigned the rod by a hair.

"Prepare my airship," Elias said. "It's time for me to claim Stillreach's Axiom Heart."

Corren inclined his head.

"And Blackvein?"

Elias turned away from the table.

"She will complete what she was made for."

He extinguished the lamp on his desk. Darkness crept slowly across the room.

"Or she will break."
