Chapter 10: The Underground World

It took four days for Casimir's network to surface the information, and those four days were spent in an education that Nora hadn't known she was receiving.

Each evening, after she had finished her work in the library, Casimir took her on walks through Prague that seemed to follow logic only he understood. They would emerge from the palace through doors that she hadn't known existed, and they would move through the city's surface world while simultaneously existing in its secret one. He would point out buildings and tell her their histories—not the histories that tourists learned, but the real ones: which blood ran beneath them, which accords had been negotiated in their basements, which families had ruled which territories for how many centuries.

She learned the names of the vampire lords who controlled particular sections of the city. She learned about Dmitri, who had ruled the Eastern Quarter since the seventeenth century and was so old that Prague had begun to grow around his territories like water around stone. She learned about Isabelle, who controlled the river routes and all commerce that moved beneath the Charles Bridge. She learned about the younger lords, ambitious creatures who had existed for only a century or two and were still capable of being reckless.

She met the human administrators who knew what was happening in their territories and kept careful silence. They were marked people, these humans, bearing the scars of negotiated contact with the vampire world. They wore fine clothes and lived in beautiful apartments and asked no questions about how their paychecks appeared or what they had agreed to in exchange for their steady, comfortable existence.

She encountered the merchants who specialized in acquiring rare objects and asking no questions about acquisition methods. One of them was a woman named Petra who ran a bookshop in the Jewish Quarter and who, when Casimir brought Nora to her establishment, simply nodded in recognition and produced from her back room a collection of manuscripts that didn't appear in any official record.

But most importantly, she was introduced to the archivists of the vampire world: individuals who kept records that no human authority would ever see, who understood the city's secret history in the way that historians understood public history, who had built elaborate systems of cataloguing and preservation that paralleled her own work in ways that made her feel suddenly less alone in her obsession with order and documentation.

It was an architecture of complexity that made the Prague municipal archive look like a children's picture book.

Nora found herself taking mental notes of everything, cataloguing the structure of power in the same way she catalogued texts. She asked questions. She listened. She began to understand that knowledge was currency in this world the way it was currency in academic circles, and that Casimir's library had been built as much as a repository of power as a collection of books.

On the fourth evening, as they sat in the library's reading room, Casimir received a visitor. A man of indeterminate age, bearing the marks of someone who'd spent considerable time in Prague's underground world. He and Casimir spoke in Czech too rapid for Nora to follow, but she watched Casimir's expression shift as the man spoke, watched the careful control slip slightly to reveal something like anger, then return.

When the visitor left, Casimir sat in one of the chairs for a very long time without speaking.

"They have your sister," he said finally. "Or they did, three days ago. A faction within the court, minor players, ambitious in the way that ambitious creatures are when they lack the power to back up their ambitions. They took her as leverage, or bait, or weapon. The reports are unclear. But they took her specifically because she was researching the archives, because she had begun to understand the shape of what was hidden beneath the city."

Nora felt her heart rate accelerate. "Where is she? Is she safe? Can we go get her?"

"In a moment," Casimir said. He stood and moved to the shelves at the eastern end of the library, ones that Nora had never seen him access. He pressed something against the wood, and the shelves shifted, revealing a chamber that went very deep into the stone. He descended without looking back to see if she followed.

She followed.

The chamber was vast, roughly hewn, predating even the baroque palace that contained it. And in the center of this chamber, sealed in a way that made the glass box containing Casimir look like a trivial preservation effort, was a vault. Stone. Magic. Multiple layers of warding that made the air vibrate with their presence.

"Two hundred years ago," Casimir said, standing before the vault without touching it, "I learned that there are limits to what a creature like me can become. I learned what happens when power meets hunger, when immortality meets the desire to remake the world according to one's own aesthetics. I learned what happens when one person decides they know better than history what history should contain."

He was very quiet.

"I created something," he said. "Through magic and will and a disregard for the consequences of transformation. I created it with the very best intentions: to protect the city, to defend the bloodlines I cared for, to ensure that certain kinds of power never fell into hands I deemed unworthy. But creation is not protection. It is only creation. And what I created began to want things I had not anticipated it would want. It began to become something other than what I had designed it to be."

Nora understood, without being told, that she was listening to a confession that Casimir had not made to anyone else. That this had been sealed along with the vault.

"I put it here," he continued, "and I sealed it with magics that I spent three decades learning. I sealed it with the understanding that sealing was not the same as destroying, that I was not yet willing to unmake what I had made. But I was also not willing to let it exist in the world. So it sleeps, as I slept. An impasse. A compromise between my desire to protect and my refusal to completely annihilate something that had once meant so much to me."

He turned to look at her, and his eyes were profoundly sad.
