Chapter 66: The Promise That Remained

Rin didn’t sleep well.

Not because of a nightmare, but because of another memory.

Something much simpler kept him awake. A sentence.

The one you promised.

He stared at the ceiling.

"Who are you?"

Nothing answered. Rin turned onto his side.

"And what did I promise?"

Still nothing. He pulled the blanket over his head.

"This is ridiculous."

A few seconds later, he pushed it away again. Sleep was clearly not interested in cooperating.

Eventually, Rin got out of bed and went to the window. The fortress was quiet. Most of the lights were gone.

Only a few remained in the distant corridors. Then Rin noticed something.

A light. Far beyond the fortress walls. Deep inside the forest.

A faint golden glow. Rin narrowed his eyes.

"...That wasn’t there before."

He watched it for several seconds. The light disappeared.

Rin frowned. He had a terrible feeling about this. Which usually meant he was going to investigate.

He sighed.

"I really need better hobbies."

Rin quietly left his room. He had made it halfway down the corridor when a familiar voice stopped him.

"Where are you going?"

Rin froze. He slowly turned. Kaelith stood near one of the pillars.

Rin stared.

"Why are you awake?"

"I could ask you the same."

"I asked first."

Kaelith smiled.

"Couldn’t sleep."

"Me neither."

Rin looked toward the forest. Kaelith followed his gaze.

"You saw something?"

"Maybe."

"Rin."

"A light."

"Where?"

"The forest."

Kaelith became serious.

"Then we’re going together."

Rin sighed.

"I knew you’d say that."

"Good."

"You really enjoy following me into dangerous places."

"No."

Kaelith paused.

"I enjoy making sure you come back."

Rin looked at him. His face became warm.

"...That’s different."

"Yes."

Rin smiled.

"Fine."

They left together. The forest was quiet. Rin walked beside Kaelith, listening to the wind. Every few steps, he glanced toward the trees.

"Do you hear anything?"

Kaelith shook his head.

"No."

Rin stopped.

"Wait."

Kaelith stopped too. Rin listened. Nothing.

Then—

a faint whisper.

"Don’t follow..."

Rin’s eyes widened. He looked at Kaelith.

"Did you hear that?"

Kaelith frowned.

"No."

Rin’s heart tightened. The voice had been meant for him. He didn’t tell Kaelith what it said.

Instead, he looked deeper into the forest.

"Maybe we should go back."

Kaelith looked at him.

"You don’t mean that, no?"

Rin sighed.

"No."

"I thought so."

They continued. The farther they went, the colder the air became. Then Rin saw something between the trees.

A small stone. Ancient. Covered in moss.

A symbol had been carved into it. The same symbol from the ruins.

Rin approached. Kaelith stayed beside him. Rin touched the stone. Nothing happened.

He waited. Still nothing. Then a tiny crack appeared.

The stone opened. Inside was a small silver object.

Rin picked it up. It looked like a key.

Kaelith frowned.

"What does it open?"

"I don’t know."

Rin turned it over. There was a tiny inscription.Only one word.

HOME.

Rin stared.

"Home?"

Kaelith looked at him.

"Do you remember it?"

"No."

Rin genuinely didn’t remember. He closed his fingers around the key.

Something about it felt incredibly sad. Not frightening.

Sad. Like someone had been waiting for this object to be found.

They returned to the fortress before dawn. Rin hid the key inside his desk.

He didn’t want anyone else asking questions yet. Not because he distrusted them.

He simply didn’t know what he had found and he had learned something important.

Sometimes a mystery needed to remain small before it could become understandable.

He went to breakfast. Sol was already there. He looked at Rin.

"You were outside."

Rin stopped.

"How do you know?"

"You have leaves in your hair."

Rin touched his head.

"...Oh."

Sol sighed.

"Where did you go?"

"The forest."

"Why?"

"I couldn’t sleep."

Sol stared at him. Rin waited. Sol wasn’t accusing him of anything. He was simply worried.

"I found something."

Sol’s expression softened.

"What?"

Rin hesitated.

"A key."

"Do you know what it opens?"

"No."

Sol nodded.

"Then don’t try to force it."

Rin smiled.

"You’re starting to sound like Kaelith."

"Someone has to."

Rin laughed. Sol pushed a plate toward him.

"Eat."

Rin stared.

"You people are obsessed with feeding me."

"Yes."

Rin picked up the fork.

"Fine."

Later that morning, Selena found Rin in the library.

"You wanted to see me?"

Rin nodded.

"I need help with something."

She sat down.

"What?"

Rin placed the silver key on the table. Selena examined it.

"I’ve never seen this."

"Neither have I."

She turned it over. Then stopped.

"Wait."

"What?"

She pointed at the bottom.

"There are letters."

Rin leaned closer. Very faint. Almost erased.

E... L...

Only two letters. Rin frowned.

"Does that mean anything?"

Selena shook her head.

"No."

Rin put the key away.

"Okay."

Selena watched him.

"You’re not going to ask more?"

"I don’t know enough yet."

She smiled.

"You’re learning."

Rin laughed.

"Everyone keeps saying that."

That afternoon, Kaelith was in his office. Rin entered without knocking. Kaelith looked up.

"You’ve learned something."

Rin smiled.

"How did you know?"

"You have that expression."

"What expression?"

"The one you get when you’ve found another problem."

Rin laughed.

"Fair."

He placed the key on the desk Kaelith stared at it.

For several seconds, he didn’t speak. Then his fingers touched the edge.

The moment they did—

Kaelith’s expression changed. Rin immediately noticed.

"Kaelith?"

Kaelith pulled his hand back.

"I..."

He looked confused.

"What?"

"I don’t know."

Rin waited. Kaelith stared at the key.

"I saw a door."

"What kind of door?"

"Wood."

"Where?"

"I don’t know."

"What else?"

Kaelith closed his eyes.

"There was someone standing beside me."

Rin’s heart beat faster.

"Who?"

"I couldn’t see."

"Anything else?"

Kaelith frowned.

"A voice."

"What did it say?"

Kaelith opened his eyes.

"It said..."

He paused.

"...’Come home.’"

Rin stared at him. The key, there was an inscription.

HOME.

A strange feeling passed through Rin. He didn’t know why.

But suddenly, the key didn’t feel like a random object anymore. It felt like something connected to both of them.

Rin slowly picked it up.

"Maybe this belongs somewhere."

Kaelith nodded.

"Maybe."

That night, Rin returned to the forest. Kaelith was beside him.

They followed the same path.

Past the old tree. Past the stream. Past the stone where Rin had found the key.

Then Rin noticed something. The path continued. He had never noticed it before.

They followed it. Eventually, they reached a clearing. In the center stood an old stone arch.

Rin stared.

"There."

Kaelith looked at it.

A small golden symbol was carved into the center. Rin took out the key. It began glowing.

Kaelith stepped closer.

"Try it."

Rin raised the key but there was no lock.

Instead, the key floated from his hand.

It moved toward the symbol.

Then—

click.

The arch lit up. A doorway appeared. Not a physical door.

A shimmering opening. Beyond it was darkness.

Rin stared. Kaelith moved closer.

"Should we go in?"

Rin looked at him.

"Absolutely not."

Kaelith smiled. Rin laughed.

"Why are you smiling?"

"Because you’re finally learning."

Rin looked back at the doorway.

"Tomorrow."

"Tomorrow?"

"We’ll investigate it tomorrow."

Kaelith nodded.

"Agreed."

Rin started walking away. Then he stopped. A whisper came from inside the doorway.

This time, Rin clearly heard it.

"You came back."

Rin froze. He turned. The doorway remained open. Kaelith looked at him.

"What happened?"

Rin stared into the darkness. He could feel something inside.

Something old. Something waiting.

And for the first time... the voice didn’t sound threatening.

It sounded relieved.

Rin finally whispered:

"I think someone was waiting for me."

Kaelith looked at the doorway.

"Then tomorrow, we’ll find out who."

Rin nodded.

They walked back toward the fortress together. Behind them, the doorway slowly closed.

But just before it disappeared, a final whisper reached Rin.

"Not yet, my child."

Rin stopped. His heart tightened.

My child?

He looked back.

Nothing remained. And for the first time, Rin wondered whether the forest wasn’t trying to lure him somewhere.

Maybe it had been protecting something. Maybe it had been protecting him.

But from what? And from whom?

Rin didn’t know.

Not yet.
