Chapter 23 — Hidden Ink, Binding Blood

That part of my story belongs to her.

I only learned what happened much later, from the notes she left behind and the things Cassian finally admitted when there was no point hiding anymore.

By then, every secret had already done its damage.

It started with blood.

Cassian came back from scouting with a cut along his ribs and the kind of expression he used whenever he wanted everyone to believe something hurt less than it did.

Seris took one look at him.

"Sit."

"I'm fine."

"You're bleeding on the floor."

"Still technically fine."

She pointed at the chair.

Cassian sat.

I was outside checking the road, which meant he had no one to help him argue.

Unfortunate for him.

Seris cut away the torn side of his shirt and cleaned the wound.

"How did this happen?"

"Branch."

She stared at him.

"A branch stabbed you?"

"Very aggressive tree."

"Cassian."

He sighed.

"Scout patrol."

"Council?"

"Didn't stop to ask."

The cut wasn't deep, but something around it bothered her.

A faint silver mark ran beneath his skin.

Not from the blade.

Older.

Seris leaned closer.

"What is that?"

Cassian looked down.

His whole body went still.

"Nothing."

She touched the mark.

He flinched hard enough to nearly knock the bowl from her hand.

"That's not nothing."

"Seris."

The mark flashed.

Only once.

A circle.

Three intersecting lines.

Then it vanished beneath his skin.

Seris knew the pattern.

She'd spent weeks reading First Crown records.

It was a Council cipher.

Not written in ink.

Written into him.

Cassian stood too quickly.

"We need to move."

"Sit down."

"I'm serious."

"So am I."

His eyes met hers.

For a second, something passed between them.

Fear.

Not of her.

Of what she'd just seen.

Cassian pulled his shirt closed.

"Forget it."

Seris folded her arms.

"You've known me for years."

"I know."

"So you already know how likely that is."

Despite himself, he almost smiled.

Then the sound of my voice carried from outside.

Cassian looked toward the door.

"I'll explain later."

He left before she could stop him.

Later.

Another dangerous word.

Seris waited until night.

We sheltered in the remains of an old courier house after rain made the northern road useless. Half the roof was gone, but the basement stayed dry.

Cassian took first watch.

I slept near the stairs.

Seris pretended to sleep.

When Cassian changed watch with me before dawn, she noticed him slide something beneath a loose floorboard.

He left.

She waited.

Then lifted the board.

Inside was a strip of black paper covered in silver symbols.

Council cipher.

The same pattern she'd seen beneath Cassian's skin.

Seris stared at it.

Then whispered, "You idiot."

The message itself was short.

SAFEHOUSE SEVEN REMAINS AVAILABLE.

ANCHOR STATUS CONFIRMED.

ARCHIVE COPIES SECURED BELOW FOUNDATION.

She read the last line twice.

Then looked around.

Courier houses had false foundations.

Old spies loved them.

Seris loved old spies.

She found the hidden latch beneath the fireplace.

A section of stone lifted.

Stairs disappeared underground.

She should've woken me.

She didn't.

Maybe she was scared I'd confront Cassian before she knew the truth.

Maybe she was scared there wouldn't be a truth she could survive knowing.

The room below smelled like dust.

Shelves lined every wall.

Most were empty.

One wasn't.

Letters.

Dozens.

Some carried Ortheon's seal.

Others carried Cassian's.

Seris opened the first.

My travel route to Halcyon Crossing.

The second listed the inns I avoided because crowds gathered there.

The third contained my preferred watch rotations.

The fourth described how exhaustion made my magic unstable.

Her hands started shaking.

She kept reading.

Zyrion responds quickly to civilian distress.

He is more likely to abandon strategic objectives if children are at immediate risk.

He refuses protective escorts when he believes they restrict civilian movement.

He sleeps poorly after large engagements.

He will prioritise Seris Elowen and Cassian Vale over his own safety.

Seris stopped.

Her name sat there in Cassian's handwriting.

Not a Council guess.

Not an enemy's observation.

His.

She grabbed another letter.

A private conversation.

Words I'd said beside a campfire years earlier.

I want somewhere nobody knows my name.

Another.

His refusal of the Crown is absolute. Direct force will make him resist harder.

Another.

Do not threaten Seris. He will stop thinking strategically.

That one had been underlined by someone else.

Seris went pale.

Sunfall Plaza.

The masked attackers.

Her.

She finally understood.

Cassian hadn't arranged it.

But he'd handed them the weapon they used.

She kept searching.

Then she found the invitation.

The original invitation to the House of Still Waters.

Not the copy we'd received.

This one had notes in the margin.

VALE HAS CONFIRMED ATTENDANCE.

SUBJECT TRUST REMAINS HIGH.

ELOWEN WILL PRESENT EVIDENCE.

ACTIVATE COVENANT ON ENTRY.

Seris sat down.

For a while, she couldn't move.

Cassian had known.

Maybe not everything.

Enough.

More than enough.

She wanted to hate him.

That would've been simpler.

Then she found the final file.

It wasn't paper.

A thin crystal tablet rested inside a lead case.

She touched it.

Magic unfolded across the room.

A human-shaped diagram appeared.

Cassian.

Silver lines ran through his chest, spine, wings, and Soul Crown.

At their centre sat the same cipher she'd seen beneath his skin.

EMERGENCY COVENANT ANCHOR: CASSIAN VALE.

Seris stopped breathing.

She read.

The ritual at the House of Still Waters required three conditions.

Instability.

Threat to civilian life.

And approval from a bonded anchor recognised by the subject.

Cassian's signature glowed beneath the final line.

Then she saw the part he hadn't known.

ANCHOR LINK SHALL REMAIN ACTIVE UNTIL COVENANT FULFILMENT.

She read further.

The Council hadn't merely used his permission.

They'd bound Cassian to the First Crown.

If the ritual activated again, they could channel Crown authority through him.

His body had become a living key.

Worse, forcefully breaking the connection could kill him.

Seris covered her mouth.

"Idiot."

This time, the word broke.

Cassian hadn't just helped build my cage.

He'd locked himself into it with me.

A floorboard creaked upstairs.

Seris killed the crystal display.

Footsteps.

Cassian.

She put everything back except three letters and the crystal tablet.

Then climbed upstairs.

Cassian stood near the broken window.

He saw her face.

Then the papers in her hand.

Every bit of colour left his.

"Seris."

She held up one letter.

"How long?"

He said nothing.

"How long, Cassian?"

His eyes moved toward the stairs where I slept.

"Keep your voice down."

Her expression twisted.

"You're worried he'll hear us now?"

"Please."

"Don't."

He flinched.

Seris stepped closer.

"You wrote down his weaknesses."

"I was trying to help."

"You told them about me."

"I didn't know they'd use it like that."

"You told them he stops thinking when I'm threatened."

"I KNOW."

The shout escaped him.

Upstairs, I shifted in my sleep.

Both froze.

Cassian lowered his voice.

"I know."

Seris stared at him.

Then placed the crystal tablet against his chest.

The hidden cipher beneath his skin lit silver.

His face changed.

"You found that too."

"They bound you."

"I know."

"No, you don't."

Her voice shook.

"This doesn't end when you decide to walk away. You're still connected."

Cassian looked toward the floor.

"Then don't tell him yet."

Seris almost hit him.

"Are you insane?"

"Probably."

"He deserves the truth."

"I know."

"Stop saying that!"

Cassian finally looked at her.

There were tears in his eyes.

"If you tell him now, he'll try to cut the bond."

Seris went still.

They both looked toward Epitaph resting beside me upstairs.

The blade that severed contracts.

Oaths.

Magic.

Souls.

"If he cuts it wrong," Cassian whispered, "the Crown takes my heart with it."

Seris hated that she understood.

Hated even more that I would've tried anyway.

Probably without hesitation.

"What do you want?"

"One conversation."

"With him?"

Cassian shook his head.

"With you."

She stared.

"Tomorrow. Away from Zyrion."

"Why?"

"Because you deserve every answer before he decides whether I live long enough to give them."

Seris folded the letters.

"No."

Cassian's face fell.

"I'm choosing the place."

He blinked.

"You'll come alone. No Council. No messages. No tricks."

"Agreed."

"And if you lie to me once, I tell him everything."

Cassian closed his eyes.

"Fair."

Seris walked past him.

Then stopped.

"Cassian?"

He turned.

She looked at the man who'd once stolen pastries with us.

The man who'd promised to break my cage.

The man who'd become part of its lock.

"I really hope there's something left for you to explain."

She went upstairs.

Cassian stayed below.

I slept through all of it.

That's the part that hurts most.

While Seris uncovered every letter written behind my back, I was only a few steps away.

Close enough to reach.

And somewhere beneath the silence, the truth waited between us like another blade, one none of us yet understood would soon be drawn against someone we loved.

Still completely in the dark.
