Kingdom of Ash (Throne of Glass #7) by Sarah J. Maas

He hadn’t told Manon it was likely a suicide mission, too. He’d barely talked to her at all since the forest clearing. They’d left with the dawn, when she’d announced to Glennis and the Crochans what she planned to do. They could fly to the Ferian Gap and return to that hidden camp within the Fangs in four days, if they were lucky.

She’d asked the Crochans to meet them there. To trust her enough to return to their mountain camp and wait.

They had said yes. Maybe it was the grave the Thirteen had dug all day, but the Crochans said yes. A tentative trust—just this once.

So Dorian had flown with Asterin. Had used each frigid hour northward to slowly alter his body.

You want to go to Morath so badly, Manon had hissed again before they’d left, then let’s see if you can do it.

A test. One he was glad to excel at. If only to throw in her face.

Manon knew of a back door that only the wyverns took into the Northern Fang, along with any human grunts unlucky enough to be bound to this place. Asterin and Manon had left the Thirteen farther in the mountains before approaching, and even then they’d stopped far away enough from any scouts that they’d spent hours hiking on foot, taking Asterin’s mare with them. Abraxos had snarled and tugged on the reins, but Sorrel had held him firmly.

The two mammoth peaks flanking the Gap grew larger with each passed mile. Yet as he approached the southern side of the Fang, he hadn’t realized how massive, exactly, they were.

Large enough to hold an aerial host. To train and breed them.

This was what his father and Erawan had built. What Adarlan had become.

No wyverns circled in the skies, but their roars and shrieks echoed from the pass as he strode for the ancient gates that opened into the mountain itself. Behind him, led by a chain, Asterin’s blue mare followed.

Another trainer bringing back his mount after a trip for some air. The few guards—mortal men—at the gates barely blinked as he appeared around a rocky bend.

Dorian’s palms turned sweaty within his gloves. He prayed the shifting held.

He would have no way of knowing, though he supposed few here would recognize his natural face. He’d picked coloring close enough to his own that should the tapestry within himself unravel, someone might dismiss the altering of his skin tone, his eyes, as a trick of the light.

Narene huffed, yanking on the reins. Not wanting to go near this place.

He didn’t blame her. The reek from the mountain set his knees wobbling.

But he’d spent years schooling his expression against the headache-inducing perfumes his mother’s courtiers wore. How far away that world seemed—that palace of perfume and lace and lilting music. Had they not resisted Erawan, would he have allowed it to still exist? Had they bowed to him, would Erawan have maintained his ruse as Perrington and ruled as a mortal king?

Dorian’s legs burned, the hours of walking taking their toll. Manon and Asterin lurked nearby, hidden in the snow and stone. They no doubt marked his every move while he inched closer to the gates.

His parting words with Manon had been brief. Terse.

He’d dropped the two Wyrdkeys into her awaiting palm, the Amulet of Orynth clinking faintly against her iron nails. Only a fool would bring them into one of Erawan’s strongholds. “They might not be your priority,” Dorian said, “but they remain vital to our success.”

Manon’s eyes had narrowed as she pocketed the keys, utterly unfazed at holding in her jacket a power great enough to level kingdoms. “You think I’d toss them away like rubbish?”

Asterin suddenly found the snow to be in need of her careful attention.

Dorian shrugged, and unbuckled Damaris, the sword too fine for a mere wyvern trainer. He passed it to Manon, too. An ordinary dagger would be his only weapon—and the magic in his veins. “If I don’t come back,” he said while she tied the ancient blade to her belt, “the keys must go to Terrasen.” It was the only place he could think of—even if Aelin wasn’t there to take them.

“You’ll come back,” Manon said. It sounded like more of a threat than anything.

Dorian smirked. “Would you miss me if I didn’t?”

Manon didn’t reply. He didn’t know why he expected her to.

He’d taken all of a step, when Asterin clasped his shoulder. “In and out, quick as you can,” she warned him. “Take care of Narene.” Worry indeed shone in the Second’s gold-flecked black eyes.

Dorian bowed his head. “With my life,” he promised as he approached her mount and grasped the dangling reins. He didn’t fail to miss the gratitude that softened Asterin’s features. Or that Manon had already turned away from him.

A fool to start down this path with her. He should have known better.

The guards’ faces became clear. Dorian embraced the portrait of a tired, bored handler.

He waited for the questioning, but it never came.

They simply waved him through, equally tired and bored. And cold.

Asterin had given him a layout of the Northern Fang and the Omega across from it, so he knew to turn left upon entering the towering hallway. Wyvern bellows and grunts sounded all around, and that rotting scent stuffed itself up his nose.

But he found the stables precisely where Asterin said they’d be, the blue mare patient while he loosely tied her chains to the anchor in the wall.

Dorian left Narene with a soothing pat to her neck, and went to see what the Ferian Gap might reveal.
