The sphere rotated. A single ruby, the size of her thumbnail, flared to life in midair. It was perfect—no, it was too perfect. The Matrix’s simulated light bent around it in a way that violated known optics.

Friya had been staring at the Matrix’s output for three hours. The commission was impossible: a crown for the Sun Prince, set with a thousand stones, each one needing to channel light into a single, blinding point. The 9’s simulations kept failing. On the fifteenth holographic render, a stone in the back arc always went dark. Always the same stone.

By dawn, the Matrix 9 was a silent, dark sphere. Friya held a single, flawed ruby in her palm—a ruby that whispered old jokes and cutting techniques from three decades past.

Her blood went cold. Only one artificer ever used that mark. Kaelen, who had disappeared thirty years ago, the same year the Matrix 9 was completed. He had been her teacher. He had also been accused of treason—of hiding a message inside the machine's logic.

The inspectors found her sitting on the workshop floor, the crown design replaced by a single word burned into every holographic pane:

She spoke the old command words, the ones from the original Gemvision codex. "Matrix, show me the maker's mark."

Tonight, the Dawnhold cathedral-workshop was silent, save for the low thrum of the Gemvision Matrix 9. The machine was a wonder of crystalline computation: a sphere of interlocking diamond lenses, each one a processor, each one humming with the light of a captive star shard. It could visualize any gem, any cut, any setting in perfect, glowing holography.

Friya hated the name. "Fri" — a clipped, cheerful abbreviation for a woman who felt anything but. She preferred her full designation: FRI-7, Senior Artificer of the Dawnhold Guild.

The ruby’s interior swirled. A tiny, perfect glyph appeared: .

"Matrix," Friya said, her voice steady. "Run protocol Dawnhold. Authorization: FRI-7."

And Kaelen’s face appeared in the central facet. Not a recording—a ghost of code, a consciousness woven into the gem-light.

"You sabotaged the simulation," she said.
