THE EXILED MATE OF A RUTHLESS KING 👑

FAULT LINES

Seren

Seren had always loved the quiet hours before the castle woke.

The North was still wrapped in pale blue light when she finished breakfast, a book open in her lap, her boots kicked off beneath the table. Snow drifted lazily past the tall windows, and for a moment, everything felt…steady.

She was halfway through a chapter when hurried footsteps echoed down the corridor.

“Miss Seren?”

She looked up instantly.

A young healer stood in the doorway, breathless. “The emergency ward needs help. We’ve had an influx—children, mostly. Panic injuries. We could really use you.”

The book was forgotten in seconds.

“I’m coming,” Seren said, already on her feet.

Helping wasn’t a choice. It never had been.

She moved through the halls with purpose, sleeves rolled up, hair pulled back as she crossed into the hospital wing. The air was already thick with fear crying children, frantic parents, healers moving too quickly to hide their nerves.

Seren stepped in like she belonged there.

“Alright,” she said calmly, voice carrying without shouting. “You—bring me clean water and cloth. You, stay with that child and keep them talking. No one moves alone.”

The chaos bent around her.

She knelt beside a little boy with a gash on his arm, murmuring reassurance as her hands glowed faintly, healing magic knitting flesh with practiced ease. She remembered another child, years ago. Leo. Lysander’s brother. Blood on stone. Fear everywhere.

This was who she was.

A horn sounded somewhere distant.

Then the lights flickered.

Healers froze.

Another horn but closer this time. Deeper. A warning.

“Lockdown!” someone shouted.

The doors slammed shut with a heavy clang as protective wards activated. The air grew colder. Outside the ward’s windows, fog rolled in unnaturally fast, thick and silver, pressing against the glass.

Seren’s heart skipped but she didn’t panic.

“Everyone stay here,” she ordered. “Children in the center. No one opens anything until we’re cleared.”

She caught her reflection briefly in the glass eyes bright, jaw set.

Cassius will handle this, she told herself.

He always did.

Cassius

Cassius was mid-discussion over border logistics when the room went dark.

Not the lights his instincts.

The bond went taut.

Danger.

“Report,” he snapped, already standing.

A guard burst in. “Breach in the Arctic Crownland perimeter. Fog spells deployed. Multiple hostile signatures—rogues.”

The word hit like ice in his veins.

“Axel,” Cassius said sharply. “With me. Callan—find Seren. Now.”

Callan was already moving. “On it.”

Cassius didn’t wait.

The moment he hit the outer grounds, the fog swallowed everything. It dampened sound, distorted distance, muddled lesser wolves’ senses.

A clever attack.

Too clever.

Shapes lunged from the mist.

Cassius shifted mid-stride.

His wolf exploded into the world—massive, dark, lethal. The first rogue didn’t even scream before its throat was torn out. Another came from the side. Cassius met it head-on, snapping bone, slamming bodies into stone.

They tried to overwhelm him.

They failed.

Even when one dropped to its knees, hands raised, sobbing apologies—

Cassius hesitated only long enough to see the lie in its eyes.

It lunged.

His wolf snapped its neck with a single brutal twist.

No mercy.

Not today.

Axel fought beside him seamlessly, blades flashing, movements precise. Within minutes, the fog began to thin. Bodies littered the snow.

The wards hummed back to life.

The danger passed.

Cassius shifted back, blood on his hands, chest heaving.

“Status,” he demanded.

Axel touched his comm. “Threat neutralized. Still confirming internal lockdowns.”

Callan’s voice crackled in, tight. “Cassius—we’re having trouble locating Seren. The hospital wing went dark during the breach.”

Something inside Cassius broke loose.

“Open it,” he ordered, already moving. “Now.”

Seren

The doors finally unlocked with a heavy click.

Relief rippled through the ward.

Seren finished binding the last wound, murmuring encouragement to a trembling mother. Only then did she feel it—the sudden, overwhelming pull.

Cassius.

She turned just as he stormed in.

For a heartbeat, they only stared at each other.

Then he crossed the room in three strides, hands framing her face, forehead pressed to hers.

“Are you hurt?” he demanded, voice rough.

“I’m fine,” she said quickly, hands gripping his arms. “Are you?”

He didn’t answer.

He kissed her.

Hard. Desperate. Like he needed proof she was real.

She kissed him back without thinking, heart racing, For a moment, nothing else existed—no fog, no threats, no past.

Just them.

When he pulled back, his hands lingered on her cheeks…then dropped.

The warmth vanished.

His jaw locked. His eyes went cold—not cruel, but distant.

“We’re going back to the castle,” he said flatly.

Seren blinked. “Cassius—”

“You should not have been here,” he continued, already turning. “During an active threat.”

Her chest tightened.

“I was helping,” she said carefully. “They needed me.”

He didn’t look at her.

“That doesn’t matter,” he replied.

And suddenly she understood.

This wasn’t anger.

It was fear—old, buried, clawing its way to the surface.

Fear of loss. Fear of history repeating. Fear of loving someone enough to lose them.

As they walked side by side through the clearing halls, Seren watched him shut himself down piece by piece.

And for the first time, she wondered:

Is this what loving him will cost?
