The Library Has Teeth

Breakfast ended with three apples, a discussion about whether I was allowed to carry a saddlebag, and Apple Bloom asking if human beings had cutie marks.

“Not exactly,” I said.

“What did they have?”

“Bad knees. Credit scores. In my case, a neurological condition that made stairs an exciting tactical problem.”

Apple Bloom considered this. “That sounds worse.”

“It had fewer horses.”

She seemed unconvinced.

Twilight waited by the farmhouse gate with a stack of books strapped across her back. Shining Shield stood beside her, scanning the road with the patient suspicion of a guard who had not slept enough. Applejack came as far as the lane, though she insisted she was only heading out to check the west orchard.

I suspected the west orchard had been invented for emotional reasons.

“Call if anything goes wrong,” Applejack said.

“I’ll try to make the call before the explosion.”

“That’d be neighborly.”

Then I followed Twilight toward Ponyville, with Shining on my other side and my tail doing something behind me that I hoped was a dignified swish rather than an anxious metronome.

The road looked different in daylight than it had under timberwolf pursuit. That was true of most things. The trees were still trees, the distant rooftops still belonged to a settlement that had no business existing outside a screen or a child’s book, but now there were carts, fences, birds, and ponies carrying baskets. Ordinary life had resumed around the impossible.

I had seen things.

That sentence arrived with such force that I nearly said it aloud. Instead, I looked ahead as the library came closer: a broad old tree with windows set into its trunk and a blue door beneath a leafy crown.

“In one of them, that’s gone,” I said.

Twilight glanced over. “What’s gone?”

“The tree. In one version of the story.” I waved a hoof at the library. “This isn’t that, and I’m glad for it. I like the tree, its books, and the people that live in it.”

Shining’s ears tilted back. “You’ve seen this place before?”

“Not this place. A version of it. Long story.”

Twilight studied me with the expression she wore whenever a sentence had just become research material. “We can add that to the interview.”

“Please don’t call it an interview. I’m already worried there will be a lamp.”

“There won’t be a lamp.”

“That’s exactly what someone with a lamp would say.”

The library’s door opened before we reached it. Spike leaned out, holding the notebook from the farm beneath one arm.

“Twilight! I got the reference shelves cleared.” He looked at me. “Also, I alphabetized the transformation books by author instead of subject, which means I may have made things worse.”

“That depends,” Twilight said. “Did you alphabetize by first name or surname?”

Spike’s face fell. “I’m going to fix it.”

I moved aside to walk next to him. “You play imagination games? Roll dice, stuff happens?”

He blinked. “Sometimes. Why?”

“I was a designer of books like that, among my other jobs.” I tapped the notebook with my horn, missed it, and tapped the floor instead. “Tabletop games. Adventures, rules, maps, people arguing about whether a door is trapped.”

“That sounds awesome.”

“It was. Also, people argued about whether doors were trapped even when the doors clearly had teeth.”

Spike grinned. “Did you make the rules?”

“Some of them. Mostly I made sure the rules gave people interesting ways to make terrible decisions.”

Twilight pushed the door open wider. “That sounds very relevant to magical research.”

“It really isn’t.”

“Everything is relevant to magical research if you organize it correctly.”

The inside of the library smelled of paper, wood, and the faint sweet trace of something baking. Books filled shelves built into the tree’s walls. Stairs curved upward around the trunk. Sunlight fell through the high windows in green-gold patches.

I stopped just inside.

The place was familiar enough to hurt and different enough to be real. I knew the shape of it from memory, but memory had never included the creak beneath my hooves, or the dragon muttering about catalog systems, or the way Twilight’s magic lifted six books at once and carried them toward a table.

Fiction had always been a map. I had forgotten that maps did not include weather.

“David?” Twilight asked.

“I’m fine.”

It was not entirely true, but it was close enough to useful.

Shining took up position beside the door. “I’ll remain here.”

“Because you trust me?”

“Because the door is a good defensive position.”

“Ah. Romance is alive.”

He gave me a flat look. “Don’t make me regret agreeing to your jokes.”

Twilight set three books on the table. Their titles were written in curling Equestrian script, which I could read without knowing why. That was another item for the mental list of things I did not understand.

The first book concerned accidental transformations. Most involved badly brewed potions, enchanted clothing, or spells cast by amateurs who had confused pronunciation with confidence. The second described teleportation failures. The third was a thin, battered volume titled *On Threshold Phenomena and the Passage Between Boundaries*.

“That one sounds promising,” I said.

“It may be mostly theoretical,” Twilight warned.

“Those are my favorite kind of theories. They have not yet had a chance to disappoint anyone.”

We began with the transformation records. Twilight read quickly, turning pages with her magic while Spike copied references into his notebook. I watched diagrams of ponies becoming birds, furniture, clouds, and, in one alarming case, a very angry soup tureen.

Nothing answered the question of how a human woke up as a unicorn.

The teleportation book was worse. It described distance, location, and the magical equivalent of making sure the destination was not occupied. The language was precise, but every example assumed the caster began and ended in the same world.

Then Twilight opened the threshold book.

The illustration on the first page showed two circles joined by a narrow, luminous bridge. Lines of magic curled around the bridge like threads tied to an anchor.

My horn prickled.

“I’m stopping,” I said.

Twilight immediately closed the book. No argument. No reaching for a measuring crystal. Just closed it.

The prickling faded to a pulse.

“What did you feel?” she asked.

“Recognition. Maybe. Not a memory exactly.”

“May I reopen it?”

I looked at Shining by the door, then at Spike, who had stopped writing. “One page. Slowly. Tell me before you show me anything.”

Twilight nodded. “The book discusses rare crossings between magically distinct regions. It says a traveler may retain an echo of the passage if the crossing is incomplete, interrupted, or anchored to a strong personal memory.”

My mouth went dry.

“Anchored how?”

“An object, a place, a name. Sometimes a sensation.” She turned the book so I could see the page without touching it. “The text says the anchor can determine what the traveler remembers first.”

The MRI machine came back to me: the hard table under my spine, the tunnel of white noise, my old body lying still while something impossible waited just beyond comprehension.

“What does ‘incomplete’ mean?” I asked.

Twilight’s eyes moved across the paragraph. “It doesn’t say. The next section is missing.”

“Of course it is.”

Spike leaned over the table. “Missing as in torn out?”

“No,” Twilight said. “As in the author never finished it.”

I laughed once, without much humor. The resonance in my horn gave a faint answering thrum.

The book’s diagram brightened.

Not the ink. The lines beneath it. A second bridge appeared between the circles, thin as a hair and pointed toward the margin. Then the light snapped off, leaving a dark scorch mark on the paper.

Shining moved from the door.

“I’m all right,” I said quickly. “No pain. No sparks.”

Twilight’s expression had gone very still. “The response occurred before I cast anything.”

“Meaning?”

“Meaning the resonance may not only remember your crossing. It may recognize descriptions of the kind of crossing that brought you here.”

That was not an answer. It was, however, a direction.

I lowered myself into a chair. My legs felt steady, but I did not trust them enough to make a point of standing.

“Can we find more books?” I asked.

“Yes,” Twilight said. “But we’ll need to be careful. If the resonance reacts to written patterns, repeated exposure might trigger stronger memories.”

“And if it does?”

“We stop.”

The simplicity of it mattered. She had said it before, and now she said it again in the place where all her knowledge lived. Stop was not failure. Stop was part of the plan.

Spike closed his notebook. “I can search the old maps and travel records. Maybe there are reports from ponies who saw something similar.”

“Thank you,” I said.

He shrugged, suddenly embarrassed. “You made books for people like me. Seems fair.”

Twilight began marking references with slips of paper. Shining returned to the door, though he kept one eye on the scorch mark.

I looked around the library—the tree, the books, the impossible people living inside a world I had once only watched from a distance.

The mystery had not opened into a door. It had opened into a page with the ending torn away.

Still, pages were better than darkness.

I reached for a blank sheet of paper with my horn. It wobbled, rose, and settled in front of me.

At the top, I wrote three words.

ANCHOR. THRESHOLD. RETURN.

Then I added a fourth beneath them.

SURVIVE.

This time, the quill did not fall.
