Celaena said nothing. It would have been easy to dismiss it as a bit of carnival dramatics, except she was seeing it for herself.

“So,” Yellowlegs said, remaining standing as well, despite the aged wooden furniture scattered around them. “Questions.”

Even though the air in the wagon was chill, the burning oven somehow made it instantly warm—warm enough for Celaena’s layers of clothing to be uncomfortable. She’d been told a story once, on a hot summer night in the Red Desert; a story about what one of the long-lost Ironteeth witches had done to a young girl. What had been left of her.

Gleaming white bones. Nothing more.

Celaena glanced at the oven again and angled herself closer to the door. Across the small sitting area, more mirrors waited in the gloom—as if even the light of the fire couldn’t reach them.

Yellowlegs leaned closer to the grate, rubbing her gnarled fingers in front of it. The firelight danced along her iron nails. “Ask away, girl.”

What had Dorian wanted to know so badly? Had he come inside this strange, smothering place? At least he’d survived. If only because Yellowlegs wanted to use whatever information she’d gleaned from him. Foolish, foolish man.

Was she any different, though?

This might be her only chance to learn what she needed to know, despite the risk, despite how messy and complicated the aftermath might be.

“I found a riddle, and my friends have been debating its answer for weeks. We even have a bet going about it,” she said as vaguely as she could. “Answer it, if you’re so clever and all-knowing. I’ll toss in an extra gold coin if you get it right.”

“Impudent children. Wasting my time with this nonsense.” Yellowlegs watched the mirrors now, as if she could see something Celaena couldn’t.

Or as if she’s already bored.

Some of the tightness in her chest loosening, Celaena pulled the riddle from her pocket and read it aloud.

When she was done, Yellowlegs slowly turned her head to Celaena, her voice low and rough. “Where did you find that?”

Celaena shrugged. “Give me the answer and I might tell you. What sort of objects does this riddle describe?”

“Wyrdkeys,” Yellowlegs breathed, eyes glowing. “It describes the three Wyrdkeys to open the Wyrdgate.”

Cold slithered down Celaena’s spine, but she said, with more bravado than she felt, “Tell me what they are—the Wyrdkeys, the Wyrdgate. For all I know, you might be lying about the answer. I’d rather not be made a fool of.”

“This information is not for the idle games of mortals,” Yellowlegs snapped.

Gold gleamed in Celaena’s palm. “Name your price.”

The woman studied her from head to toe, sniffing once. “Nameless is my price,” Yellowlegs said. “But gold will do for now.”

Celaena set five extra gold coins down on the hearthstone, the heat from the flame singeing her face. Such a small fire, but she was already slick with sweat.

“Once you know this, there is no unknowing it,” the witch warned. And from the gleam in Yellowlegs’s eyes, Celaena knew that the old woman hadn’t bought her lie about the bet for one heartbeat.

Celaena took a step closer. “Tell me.”

Yellowlegs looked toward another mirror. “The Wyrd governs and forms the foundation of this world. Not just Erilea, but all life. There are worlds that exist beyond your knowledge, worlds that lie on top of each other and don’t know it. Right now, you could be standing on the bottom of someone else’s ocean. The Wyrd keeps these realms apart.”

Yellowlegs began to hobble around the sitting area, lost in her own words.

“There are gates—black areas in the Wyrd that allow for life to pass between the worlds. There are Wyrdgates that lead to Erilea. All sorts of beings have come through them over the eons. Benign things, but also the dead and foul things that creep in when the gods are looking elsewhere.”

Yellowlegs disappeared behind a mirror, her uneven steps echoing along. “But long ago, before humans overran this miserable world, a different sort of evil broke through the gates: the Valg. Demons from another realm, bent on the conquest of Erilea, and with the force of an endless army behind them. In Wendlyn, they fought against the Fae. Try as the immortal children might, they could not defeat them.

“Then the Fae learned that the Valg had done something unforgivable. They had taken a piece of a Wyrdgate with their dark magic, and split it into three slivers—three keys. One key for each of their kings. Using all three at once, the Valg Kings were able to open that Wyrdgate at will, to manipulate its power to strengthen their forces, to allow an endless line of soldiers to pour into the world. The Fae knew that they must stop it.”

Celaena stared at the fire, at the mirrors, at the darkness of the wagon around her. The heat was smothering now.

“And so a small band of Fae set out to steal them from the Valg Kings,” Yellowlegs said, her voice coming nearer again. “It was an impossible task; most of those fools didn’t return.

“But the Wyrdkeys were indeed retrieved, and the Fae Queen Maeve banished the Valg to their realm. Yet for all her wisdom, Maeve couldn’t discover how to put the keys back in the gate—and no forge, no steel, no weight could destroy them. So Maeve, believing that no one should have their power, sent them across the sea with Brannon Galathynius, first King of Terrasen, to hide on this continent. And thus the Wyrdgate remained protected, its power unused.”

Silence fell. Even Yellowlegs’s hobbling steps had slowed.

“So the riddle is a … a map to where the keys are hidden?” Celaena asked, trembling now as she realized just what kind of power Nehemia and the others had been after. Worse, what the king might be after.

“Yes.”

Celaena licked her lips. “What might one do with the Wyrdkeys?”

“The person who holds all three Wyrdkeys would have control over the broken Wyrdgate—and all Erilea. They would be able to open and close the gate at will. They could conquer new worlds or let in all sorts of life to bend to their cause. But even one key could make someone immensely dangerous. Not enough power to open the gate, but enough to be a threat. You see, the keys themselves are pure power—power to be shaped as the wielder wills it. Tempting, isn’t it?”

The words echoed through her, blending with Elena’s command to find and destroy the source of evil. Evil. Evil that had arisen ten years ago, when a whole continent had suddenly found itself at mercy of one man—a man who had somehow become unstoppable.

A source of power that existed outside of magic. “It can’t be.”

Yellowlegs only let out a confirming chuckle.

Celaena kept shaking her head, her heart beating so violently she could hardly breathe. “The king has some of the Wyrdkeys? That’s how he was able to conquer the continent so easily?” But if he’d already done that—then what further plans did he have?

“Perhaps,” Yellowlegs said. “If I were to wager my hard-earned gold, I’d say he has at least one.”

Celaena scanned the dark, the mirrors, but saw only versions of herself looking back. She heard nothing but the crackling of the fire in the oven and her own uneven breathing.

Yellowlegs had stopped moving.

“Is there anything else?” Celaena demanded.
