Chapter 3: Rules of the Threshold
The warning bell was still tolling when the floor of the corridor split open beneath them, and Mira had exactly one second to register that the stone had turned to something closer to water before Kade's arm hooked around her waist and hauled her backward onto solid ground.
"Don't step where the light doesn't reach," he said, breathless, as if this were an obvious rule she should already know. "The Threshold gets nervous when two linked wishes are active at once. It starts testing the corridors."
"Testing them how? By trying to eat me?"
"Testing them by making sure only the right feet touch the right stones." Kade did not let go of her arm, not yet, and Mira found she did not particularly want him to. "You're still new to the Ledger. It doesn't fully trust you yet. Give it time."
"Comforting."
"You get used to it," Kade said, which was not comforting either, and finally let go of her arm now that the stone beneath their feet had stopped rippling. "Most first nights involve at least one near miss with the floor. Consider yourself on schedule."
"Is there a brochure for this. Welcome to Veylorien, mind the sentient floor, please do not feed the ancient corridors."
"If there were a brochure, Corvain would have written it, and it would be entirely self serving." A flicker of something almost like humor crossed his face. "Something along the lines of, kindly consider a Ledger Trial before the floor considers eating you instead."
Despite everything, Mira found herself laughing, short and startled, the sound echoing oddly down the corridor's curved walls. "You're funnier than you let on."
"I have very little to work with most nights. I take what amusement I can get."
That was the version of the story she told herself later, the one where she made a joke instead of admitting how close she'd come to falling through the floor of a world she didn't understand into whatever waited underneath it.
They reached the Hollow Archive an hour later, after a walk that took them past the upside down courtyard again, through a narrow stair that spiraled both up and down at once in a way Mira's eyes refused to process correctly, and finally through an arch carved with symbols that looked, unsettlingly, like the same fist shaped handle from the amber door, repeated over and over into the stone.
The Archive itself was nothing like the Ledger's round chamber. Where Corvain's domain had gleamed with polish and gold ink, the Hollow Archive was dim, dusty, and full of shelves that seemed to have been built by someone who had given up on organization several centuries ago. An old woman sat behind a desk made of driftwood, sorting a pile of loose parchment with the unhurried patience of someone who had all the time in any world.
"Warden Thorn," she said, without looking up. "You haven't visited in longer than usual. I was beginning to think you'd finally been reassigned."
"Not yet, Old Maren." Something in Kade's posture eased slightly, the way it hadn't around Corvain. "I need to trace a linked wish. Two entries, minutes apart, same origin point."
Old Maren's eyes flicked up, settling on Mira with an assessment so thorough it felt almost physical. "The girl from the amber door. Word travels fast when the Ledger tolls twice." She set down her parchment. "Linked wishes are old magic, dear. Older than Corvain, though he'd hate to hear anyone say so. Sit. This will take explaining."
Mira sat on a stool that wobbled dangerously and glanced sideways at Kade, who had folded himself onto a similar stool with the ease of long practice.
"A linked wish," Old Maren began, "happens when two people who share a strong bond make a wish on the same door within a short span of time, usually because one is reacting to the other. Fear does it. Love does it. Grief does it. The bond ties the wishes together, so that unmaking one affects the other." She tapped a wrinkled finger against the desk. "If you unmake your wish, girl, and the linked wisher hasn't unmade theirs, the backlash could unmake both of you the wrong way. Badly. Permanently."
"So we have to solve them together," Mira said slowly. "Whoever this second person is."
"You'll need to find them first," Old Maren said. "And with two active entries, the Threshold will keep testing anyone who moves through it, the way it just tested you in that corridor. It doesn't like uncertainty. Linked wishes are the most uncertain thing there is."
Kade leaned forward. "Can you trace the origin point? If it's tied to the same door, the same room, there should be a signature."
Old Maren studied him for a long moment; something passed between the two of them, quiet and complicated, that made Mira feel, for a second, entirely outside a conversation they weren't actually having out loud.
"I can trace it," the old woman finally said. "But it will cost you something, Warden. It always does. And I think you already know what I'm going to ask for."
Kade's jaw tightened. "Not that."
"It's the fairest price I have for something this precise."
"Then I'll find another way."
"Find another way," Mira repeated. "Kade, we don't have another way, or we wouldn't be here. What is she asking for?"
Kade did not answer immediately, and Old Maren, with the patient cruelty of someone very old and very used to watching young people avoid difficult truths, answered for him.
"A year of his remaining memory, dear. Wardens pay in the only coin the Threshold considers valuable. Time, or memory, or both. He's already given more of both than most wardens do in a lifetime, and I imagine he'd rather not give more on your account."
The silence that followed felt very loud.
"No," Mira said. "Absolutely not. We are not doing that."
"We don't have another lead," Kade said quietly, not looking at her.
"Then we'll make one." Mira stood up so fast the wobbly stool nearly toppled. "You told me yourself, back at the Ledger, that every day this stays unsolved costs you something. I'm not going to let you pay for my mistake with pieces of who you are. I got myself into this. I'll get myself out of it without carving anything else off of you to do it."
Kade looked at her then, really looked, in a way that made something in Mira's chest twist unexpectedly.
"You don't even know me," he said, but it came out softer than he probably meant it to.
"I know enough," Mira said. "I know you've been standing at that door for longer than you'll admit, giving pieces of yourself to a place that barely says thank you. I'm not adding to that pile just because it would be convenient for me."
Old Maren, watching this with an expression Mira couldn't quite read, cleared her throat.
"There is one other way," she said, in the tone of someone who had been waiting to see if either of them would think of it first. "Slower. Costs nothing but effort, and a bit of danger, which around here is practically free. The Threshold responds to strong feeling, as I said. If the two of you retrace the path of the wish itself, walking the corridors in the order the Threshold tested them, the echoes of that second wisher's feeling should be strong enough to follow, like a scent. It won't be exact. It won't be safe. But it won't cost either of you a single memory."
"Then that's what we do," Mira said immediately.
Kade studied her for a long moment, something unreadable working behind his eyes, and then, for the second time since she had met him, something that was almost a real smile touched the corner of his mouth.
"You're stubborn," he said. "It's going to get you into a great deal of trouble."
"I opened a cursed door over a history essay. I think we've already established that."
Old Maren snorted, an unexpectedly youthful sound from someone so old, and began gathering a set of small brass instruments from a drawer, the kind that looked like compasses but hummed faintly when she touched them.
"Take these. They'll pull toward the strongest echo of feeling in any room you enter. Follow them, and don't let go of each other's hand once you're inside the testing corridors. If the Threshold separates you, it will treat you as two individual uncertainties instead of one linked pair, and it will be considerably less polite about deciding which of you gets to stay standing."
Mira took the small humming device, its metal warm against her palm, and did not comment on the fact that her heart had done something strange and unhelpful at the words don't let go of each other's hand.
They left the Hollow Archive as the strange gold lanterns in the corridors outside began, for reasons neither of them understood yet, to flicker in a slow, deliberate rhythm, almost like a countdown.
"That's new," Kade muttered, watching the light pulse down the hallway ahead of them.
"Is new bad."
"In Veylorien, dear," he said, echoing Old Maren without quite meaning to, "new is almost always bad."
They had taken perhaps six steps into the flickering corridor when the little brass compass in Mira's palm spun once, hard, and locked, trembling, on a direction that pointed not forward into the Archive's depths, but straight back toward the round chamber they had left an hour before, toward the tall black door marked with a book swallowing its own pages.
Toward Corvain.
