The installation began at dawn.

Rox accompanied her—coat pulled tight, brows furrowed—but silent. He knew better than to interrupt her now.

They placed the first stones in the castle’s monument, where the circle would center. Mer carefully set each one in its cradle, the stone slot lined with sigils and heat-sealed to avoid frost damage.

Then, with a spell, she and Rox vanished.

In a flicker of light, they appeared at the next location, and then the next. Each time, they placed stones with deliberate reverence, as if tucking magic into the bones of the land itself.

When they returned to the castle, snow was falling harder, curling against the windowpanes. But above the world, the barrier activated.

A low, golden pulse surged outward from the central monument.

Lines of light extended to the other four towers—like threads drawn across the kingdom—and then curved upward and down, until the glow formed a perfect sphere of protection.

It sparkled softly, like light under a frozen lake.

Mer stood just outside the monument, breath curling in the cold air.

“This barrier is spherical,” she said, voice calm. “Not just covering above—but beneath as well. If they dig under, they’ll still be blocked.”

Rox, watching with wide eyes, murmured, “This is incredible, Master.”

She turned to him, a small smile touching her lips. “Want to test it?”

He blinked. “I thought you’d never ask.”

He stepped just outside the barrier and began to chant. Dark magic flared in his palms. He hurled a sharp bolt toward the castle—the golden sphere shimmered, catching it like a net and dissolving the attack on contact.

He grinned.

“Again,” he muttered.

This time, a burst of explosion magic, loud enough to shake the frost from nearby trees. But the barrier didn’t flicker.

Rox laughed. “Oh, this is beautiful.”

Mer nodded.

Then his face turned thoughtful. “But what about intruders? What if someone slips in without using magic?”

She tilted her head. “Good question. That’s its one weakness. It’s tuned to react to magic energy and monster aura. Anyone completely mundane—or hidden—might pass through.”

Rox frowned. “So it’s not perfect.”

“It’s not meant to be,” she said. “It’s the first line. The rest… is still on us.”

He gave a low whistle and looked up at the barrier. The light moved like a slow heartbeat, pulsing from the monuments inward.

Mer looked down at her gloved hands.

The black veins had receded.

But her magic still hummed.

And around them, for the first time in weeks—Ravenrow was quiet.

---

The people of Ravenrow whispered her name with awe.

The Duchess.

The one who had created the golden barrier that shielded them from the horrors of winter migration. Since the monuments rose and the barrier enclosed their lands like a golden heartbeat, a quiet peace had returned. The guards began to smile again. Families gathered around fires instead of clutching weapons. Children played in courtyards. And all around the province, people spoke of Mer’s intelligence, of how she had saved them without shedding a drop of blood.

In a small village near the edge of Ravenrow, snow dusted the rooftops and the pine trees swayed gently in the wind. A little boy played outside, dragging a wooden sword through the snow like he was a knight.

“Don’t go too far,” his mother warned, stepping away from her laundry line. She drew a line in the snow with her foot. “Stay on this side of the yard.”

He nodded with exaggerated seriousness. She smiled and turned back to her drying clothes.

But when she turned again—

Her son was gone.

And in the distance, she heard him scream.

She ran.

Her heart froze when she saw it: a gelatinous black mass, low to the ground but moving fast. A blob with no eyes or limbs—just an endless, drooling mouth. It had swallowed the boy’s leg up to the knee, his tiny boot dangling from the edge of its shifting form.

The mother screamed and lunged forward. Her own leg was caught as she yanked the boy free—just in time. Her shoe remained behind, devoured, sizzling in the creature’s mouth.

They ran. Behind them, the blob lurched forward, too fast for something that shouldn’t even have muscles. But when it reached the barrier, it hit an invisible wall—and shrieked.

The sound was unnatural. A scraping echo, like metal bending in a storm.

Then, like a signal, monsters emerged from the woods—dozens. They gathered around the blob, circling, eyes fixed on the barrier’s flickering edge.

Then they attacked.

Claws. Fangs. Acid. Fire. Lightning.

The barrier held.

It pulsed with gold and white, deflecting every blow. The monsters growled in frustration. But the blob did not grow discouraged.

It grew hungry.

Suddenly, it turned—not toward the barrier, but toward the other monsters.

Its mouth stretched unnaturally wide and it began swallowing them.

One by one. Two at a time. A blur of motion and snapping jaws.

Some monsters tried to escape. Others fought. But the blob absorbed them, dragging them into its body until its shape turned pitch black, bloated, seething. When it turned back to the barrier, it towered above the houses, as tall as the village rooftops.

And it slammed its massive form against the barrier with a boom that echoed across the hills.

---

A villager jumped on his horse and rode hard toward the main road. He didn’t stop for breath, shouting before he even reached the soldiers patrolling nearby.

“A monster! A giant one! Krieg village—it’s trying to break through!”

The soldiers followed instantly.

When they arrived, their spines turned cold.

The blob loomed—monstrous, pulsing, eyes now forming in patches across its body like hungry mouths. Every time it slammed against the barrier, the golden light flickered.

---

Back in the castle, a knight burst through the doors, armor dripping snow.

“Your Grace—there’s a monster, larger than anything we’ve seen. The barrier’s holding, but barely. We’ve tried magic—it’s not working.”

Cecil stood, already calling for his armor.

“Where?”

“Krieg village.”

“Ready the horses. I’ll go ahead.”

As the knight ran to assemble the unit, Rox was already moving. He found Mer in the greenhouse, adjusting the positioning of mana stones with cold-reddened fingers.

He didn’t hesitate. “My lady, Krieg is under attack.”

She froze. The crystal in her hand dimmed.

Mer didn’t speak. She simply stood, dropped the stone into her pouch, and walked out.

In minutes, she was back—in trousers and shirt, hair tied up, sword at her back, and a handful of enchanted mana stones tucked beneath her cloak. Rox waited at the central monument.

“Where?” she asked, calm as frost.

“Krieg.”

She whistled, sharp and clear.

Didy appeared almost instantly, sprinting like a shadow. She stopped before Mer, tongue out, tails curling. Rox flinched. He still hadn’t gotten used to the beast.

Mer climbed onto Didy’s back and looked down at him.

“Find Cecil,” she said.

And vanished in a shimmer of magic.

Rox groaned. “Why does she always leave me behind?”

He found a horse and followed with the nearest soldiers.

---

Mer appeared just beyond Krieg village’s monument. She could hear the shouts of knights, the whistle of spells, and the screaming of the blob as it slammed again and again into the barrier.

She urged Didy forward.

Snow burst beneath her paws as she ran toward the edge of the village.

And then—Mer saw him.

Cecil, his long blue hair wet with sweat and snow, stood with the vanguard. Around him, blue fire hounds circled, flinging themselves at the beast. Arrows streaked through the sky. Spells rained down.

The blob took it all.

And only grew stronger.

It roared, more massive now, dozens of feet tall, rippling with absorbed energy. Magic only seemed to feed it.

Mer’s heart clenched.

They were doing everything they could.

But this monster wasn’t like the others.
