“It did not go well for the half-breeds,” he said after a moment. “Many were offspring of unwanted unions. Most usually chose to stay with their human mothers—their human families. But once the wall went up, amongst humans, they were a … reminder of what had been done, of the enemies lurking above the wall. At best, they were outcasts and pariahs, their children—if they bore the physical traits—as well. At worst … Humans were angry in those initial years, and that first generation afterward. They wanted someone to pay for the slavery, for the crimes against them. Even if the half-breed had done nothing wrong … It did not end well.”

He approached the doors, which opened on a phantom wind, as if the mountain itself lived to serve him.

“And the ones above the wall?”

“They were deemed even lower than lesser faeries. Either they were unwanted everywhere they went, or … many found work on the streets. Selling themselves.”

“Here in Velaris?” My words were a bare brush of air.

“My father was still High Lord then,” Rhys said, his back stiffening. “We had not allowed any humans, slave or free, into our territory in centuries. He did not allow them in—either to whore or to find sanctuary.”

“And once you were High Lord?”

Rhys halted before the gloom that spread beyond us. “By then, it was too late for most of them. It is hard to … offer refuge to someone without being able to explain where we were offering them a safe place. To get the word out about it while maintaining our illusion of ruthless cruelty.” The starlight guttered in his eyes. “Over the years, we encountered a few. Some were able to make it here. Some were … beyond our help.”

Something moved in the darkness beyond the doors, but I kept my focus on his face, on his tensed shoulders. “If the wall comes down, will …?” I couldn’t finish the words.

Rhys slid his fingers through mine, interlacing our hands. “Yes. If there are those, human or faerie, who need a safe place … this city will be open to them. Velaris has been closed off for so long—too long, perhaps. Adding new people, from different places, different histories and cultures … I do not see how that could be a bad thing. The transition might be more complex than we anticipate, but … yes. The gates to this city will be open for those who need its protection. To any who can make it here.”

I squeezed his hand, savoring the hard-earned calluses on it. No, I would not let him bear the burden of this war, its cost, alone.

Rhys glanced to the open doors—to the hooded and cloaked figure patiently waiting in the shadows beyond them. Every aching sinew and bone locked up as I took in the pale robes, the hood crowned with a limpid blue stone, the panel that could be lowered over the eyes—

Priestess.

“This is Clotho,” Rhys said calmly, releasing my hand to guide me toward the awaiting female. The weight of his hand on my lower back told me enough about how much he realized the sight of her would jar me. “She’s one of the dozens of priestesses who work here.”

Clotho lowered her head in a bow, but said nothing.

“I—I didn’t know that the priestesses left their temples.”

“A library is a temple of sorts,” Rhys said with a wry smile. “But the priestesses here …” As we entered the library proper, golden lights flickered to life. As if Clotho had been in utter darkness until we’d entered. “They are special. Unique.”

She angled her head in what might have been amusement. Her face remained in shadow, her slim body concealed in those pale, heavy robes. Silence—and yet life danced around her.

Rhys smiled warmly at the priestess. “Did you find the texts?”

And it was only when she bobbed her head in a sort of “so-so” motion that I realized either she could not or would not speak. Clotho gestured to her left—into the library itself.

And I dragged my eyes away from the mute priestess long enough to take in the library.

Not a cavernous room in a manor. Not even close.

This was …

It was as if the base of the mountain had been hollowed out by some massive digging beast, leaving a pit descending into the dark heart of the world. Around that gaping hole, carved into the mountain itself, spiraled level after level of shelves and books and reading areas, leading into the inky black. From what I could see of the various levels as I drifted toward the carved stone railing overlooking the drop, the stacks shot far into the mountain itself, like the spokes of a mighty wheel.

And through it all, fluttering like moth’s wings, the rustle of paper and parchment.

Silent, and yet alive. Awake and humming and restless, some many-limbed beast at constant work. I peered upward, finding more levels rising toward the House above. And lurking far below … Darkness.

“What’s at the bottom of the pit?” I asked as Rhys came up beside me, his shoulder brushing mine.

“I once dared Cassian to fly down and see.” Rhys braced his hands on the railing, gazing down into the gloom.

“And?”

“And he came back up, faster than I’ve ever seen him fly, white as death. He never told me what he saw. The first few weeks, I thought it was a joke—just to pique my curiosity. But when I finally decided to see for myself a month later, he threatened to tie me to a chair. He said some things were better left unseen and undisturbed. It’s been two hundred years, and he still won’t tell me what he saw. If you even mention it, he goes pale and shaky and won’t talk for a few hours.”

My blood chilled. “Is it … some sort of monster?”

“I have no idea.” Rhys jerked his chin toward Clotho, the priestess patiently waiting a few steps behind us, her face still in shadow. “They don’t speak or write of it, so if they know … They certainly won’t tell me. So if it doesn’t bother us, then I won’t bother it. That is, if it’s even an it. Cassian never said if he saw anything living down there. Perhaps it’s something else entirely.”

Considering the things I’d already witnessed … I didn’t want to think about what lay at the bottom of the library. Or what could make Cassian, who had seen more dreadful and deadly parts of the world than I could ever imagine, so terrified.

Robes rustling, Clotho aimed for the sloping walkway into the library, and we fell into step behind her. The floors were red stone, like the rest of the place, but smooth and polished. I wondered if any of the priestesses had ever gone sledding down the spiraling path.

Not that I know of, Rhys said into my mind. But Mor and I once tried when we were children. My mother caught us on our third level down, and we were sent to bed without supper.

I clamped down on my smile. Was it such a crime?

It was when we’d oiled up the floor, and the scholars were falling on their faces.

I coughed to cover my laugh, lowering my head, even with Clotho a few steps ahead.

We passed stacks of books and parchment, the shelves either built into the stone itself or made of dark, solid wood. Hallways lined with both vanished into the mountain itself, and every few minutes, a little reading area popped up, full of tidy tables, low-burning glass lamps, and deep-cushioned chairs and couches. Ancient woven rugs adorned the floors beneath them, usually set before fireplaces that had been carved into the rock and kept well away from any shelves, their grates fine-meshed enough to retain any wandering embers.
