The morning mist still clung to the trees when the first scream split the sky.

It wasn’t the scream of a human—it was sharper, clearer, and far more ancient. A dragon’s cry, but one unlike any the Riders had ever heard. The sound sent a ripple through the air, making Toothless stiffen beneath Hiccup as they soared above the treetops. A second later, the other dragons jerked mid-flight—Stormfly squawked, Hookfang flared sideways, Barf and Belch tumbled like a broken wheel.

Hiccup’s stomach twisted.

"Something’s wrong," he muttered, gripping Toothless tighter. His dragon growled, low and tense, eyes darting toward the treeline. Hiccup could feel the stiffening of muscle beneath him, the tremble of instinct that screamed: Predator.

From behind a cloudbank, something shimmered. A ghost. A blur of white refracted in the sunlight.

Then—a scream.

High-pitched. Shrill. Like the scraping of metal over ice. It pierced the air with unnatural clarity. Toothless let out a roar of pain, wings faltering as his body locked mid-flight.

"H-hang in there, bud!" Hiccup cried, wrenching the manual override on his tail fin just in time. Toothless spiraled, dazed but steady enough to land hard on a rocky ridge near the coastline.

Astrid was already circling above with Stormfly, eyes wide. “What was that?!”

But Hiccup wasn’t listening. His eyes were locked on the figure descending through the haze.

A woman.

She rode a dragon like nothing Hiccup had ever seen—white as moonlight on fresh snow, its scales glittering with an unnatural sheen. Its wings cut the air like a blade, and every beat shimmered with pearlescent light. Hiccup’s heart lurched as he watched it open its mouth for another cry—and every dragon nearby flinched again, paralyzed with invisible force.

The woman atop the beast was equally striking: long red hair braided down her back, eyes masked by a bone-white visor. Armor laced in golden furs and dragon bone. She held no net, no spear, no harpoon—only a curved dagger strapped to her thigh and the calm composure of someone who didn’t need anything else.

Toothless growled, still unsteady. Hiccup positioned himself between her and his dragon, raising a hand.

“Who are you?” he demanded. “And what kind of dragon is that?”

The woman tilted her head, and Hiccup caught a flicker of something behind the visor. Amusement? Curiosity?

“So it’s you,” she said, her voice hoarse as she ignored his questions. “The famed dragon master.”

The dragon she rode glared with bright, unnatural eyes, one pupil vertical like a viper’s, the other swirling with gold. It was... wrong. Beautiful, but wrong.

“Are you with Viggo?” Hiccup demanded. “Ryker?”

At that, the woman smiled.

“So many questions,” she said slowly, dismounting with eerie grace. “You know I pictured you taller, a few more scars.”

Toothless hissed, but didn’t pounce. Neither did the large dragon behind the woman. The standoff held, stretched tight as wire.

“Let me guess,” Hiccup said cautiously. “You’re here to steal the dragon eye.”

Her head tilted again, and this time she pulled off the visor.

Red lashes. One green eye. One blue.

“Nope,” she said. “I have no interest in that contraption my brothers enjoy obsessing over ”

She walked forward, slow, confident. “They spend all day plotting and scheming because of you. Their obsession is causing them to lose sight of...what truly matters.”

She stopped just shy of Hiccup, just far enough that Toothless’s tail twitched in readiness.

“I’ve read your letters,” she said. “Your treaties. Your declarations. Your idealism. I wanted to see the Dragon Master myself.”

She reached out as if to touch him—and Toothless snarled. She pulled back, unbothered.

“Well,” she said, turning away, “you’ll do.”

“Do... for what?” Hiccup asked, but the question felt small.

She mounted her dragon again with the ease of muscle memory, her back straight.

“To disappoint me,” she said simply. “Or to surprise me.”

Solstice shrieked again, this time not enough to paralyze but enough to disorient. By the time Hiccup and Toothless could see clearly, the skies were empty again.

Later, back at the Edge, the Riders were gathered around a lantern-lit map. Tension buzzed.

“She froze every dragon in the sky,” Astrid said grimly. “Whatever that thing is, it’s not normal.”

“Did you see how she moved?” Fishlegs muttered. “Like a knife in silk. I’ve read about predators like that in scrolls—but never human.”

Hiccup sat in silence, staring at the map, where he had crudely sketched a pearlescent dragon with three question marks beneath it. 

Just then, Trader Johann burst into the room, out of breath and wide-eyed.

“You’ve seen her? The Siren?” he asked. “Tell me it’s not true.”

“What? The Sir- do you mean the rider with the white dragon?” Hiccup asked as he stood to meet the frantic man.

Johann nodded grimly. “Eir. Viggo's Sister, the youngest. She’s the one people don’t talk about.”

“Why?” Astrid pressed.

“Because if Viggo’s the mind and Ryker’s the muscle,” Johann said quietly, “then Eir is the soul. And she... she doesn’t fight you with weapons. She fights you with truths. The ones you don’t want to hear.”

Silence followed.

Hiccup’s hand tightened on the sketch of the dragon in white. The girl who smiled like she already knew him.

And for the first time in a long while, Hiccup didn’t feel like the one holding all the cards.

He felt like prey.
