Chapter 357: The Bell That Answered

Alexandra’s hand stopped against Kumoe’s fur.

"The foreign bell?"

"We believe so."

The Lower Belfry had remained unresolved since their first expedition. They had restored the upper resonance network, sealed the corrupted spawn points feeding into the inhabited district, and stopped the Bell-Eater Cantor, but nothing below had been cleared. Darkness still remained beyond the lower gates, along with a bell whose note belonged to no known Sairren.

Mireva traced three points beneath the city.

"After you escaped the market, three lower bells rang in sequence."

Katherine leaned over the map. "Could your stolen route-song in the market have caused it?"

"Maybe." Mireva glanced briefly toward Rias. "I don’t know."

Rias said nothing. The absence of a correction seemed to satisfy Mireva more than praise would have.

"The first bell used an old return call," Mireva continued. "The second attempted the same call and failed the final resonance. Badly. None of our route-keepers would have accepted it."

Her claw moved to the lowest point.

"The third rang once."

Martin waited. "And?"

"Nothing."

"It just rang?"

Mireva nodded. "Then waited." Martin looked at the lower mark, and judging by everyone else’s expressions, he was not the only one who disliked that answer.

"Waited for what?"

"We don’t know."

Mireva moved her claw to another sealed route. "This morning, one lower seal opened for less than one breath."

Martin’s attention snapped to her. "Did anything cross?"

"No."

Rias replaced the route map with an evidence image.

[Residue recovered from Lower Belfry Seal 4.]

[Foreign metal particulate detected.]

[Tool contact confirmed.]

The image showed dark metallic flakes caught around a bronze locking plate. Rias enlarged one section.

"The particulate does not match the seal. Something made physical contact with the mechanism from the other side."

Alexandra’s eyes narrowed. "So someone is down there."

"Something using a tool was down there."

Alexandra looked at her. Rias held the look, and after a moment, Alexandra let it go.

Cassandra activated Hungerline and kept her eyes on the sealed routes. Nothing appeared, and several seconds passed before she spoke.

"I have no Hungerline."

Katherine looked toward her. "Meaning there’s no Dark Force nearby?"

"No." Cassandra shook her head. "It means I cannot detect a Dark Force monster whose hunger has been redirected toward anything on this platform. Hungerline tells me nothing about people below us."

Rias made a note without comment. Cassandra caught the movement and almost smiled before returning her attention to the map.

Martin studied Seal 4. "We should inspect it."

"No."

Mireva answered before he finished turning toward her. Martin frowned. "If something is testing the lock from below, waiting gives it more time."

"And opening sealed paths because someone wants us afraid gives them exactly what they may be waiting for."

Mireva moved around the table until she stood opposite him. "These routes were sealed before my grandparents were born. Some because of Dark Force corruption. Some because the structures failed. Others because nobody knew what remained beyond them."

She tapped three separate sections. "If I know which route is being breached, I can respond to that route. Until then, I will not open the Lower Belfry because an enemy rattled one lock."

Martin looked at the map again. She was right. If the enemy was probing them, tearing through every old seal would only expose more paths.

"All right."

Rias closed the evidence image. "We monitor the seals. The next physical change gives us our target."

Mireva nodded. Alexandra glanced toward the residential bridges. "What about the people living above them?"

"Upper shelters are prepared. Every family received an evacuation assignment today."

"How do you trust those routes if someone can reproduce your bells?"

"We don’t."

Mireva pointed toward the small tuning forks Martin had noticed beside the homes. "Nothing important is transmitted by open call anymore. Children receive touch-sign instructions. Adults use physical route markers. Couriers move in pairs."

Elisebeth looked across the city. "You changed your entire emergency system in a day?" Mireva was quiet for a moment before answering.

"We watched children walk toward the wrong bell once."

Elisebeth’s expression changed. "Right." Mireva did not need to explain further.

Martin looked over the inhabited district again. Guide lines now carried physical patterns instead of relying solely on sound. Wardens checked markers before allowing anyone onto restricted bridges, and even young Sairren touched small plates near the entrances before crossing between districts.

They had adapted quickly. Martin respected the hell out of them for it, and hated that they had needed to.

Wingbeats approached from the eastern bridge. A young Sairren runner landed on the platform with a narrow bronze case hugged against his chest and went straight to Mireva.

"Fourth watch is complete."

She turned to him. "Anything?"

"No movement at the seals."

Some tension left her shoulders, but the runner remained where he was. His claws tightened around the case instead of lowering it.

Mireva noticed. "What happened?"

"The lower bell rang again."

Every conversation on the platform stopped. Mireva’s wings shifted once behind her. "Which one?"

The runner swallowed. "None of ours."

He placed the bronze case on the table. Inside lay a thin tuning strip, and nobody touched it.

For several seconds, nothing happened. Then the strip vibrated once, followed by a second pulse. The third was so faint Martin felt it through his boots before he heard anything.

The resonance came from below, controlled and deliberate. Mireva snatched one of the upper tuning forks from its rack and struck it against the bronze platform. The true Sairren note traveled through the restored network and descended toward the sealed lower routes while everyone watched the map.

One second passed. Then two. Nothing answered.

Mireva slowly lowered the tuning fork. The lowest sealed relay flashed black, and a bell rang beneath the city. One clean note returned through the bronze.

Katherine’s fingers tightened against the edge of her tome. "That sounded exactly like yours."

Mireva did not answer. The fine feathers along her cheeks had gone still.

Alexandra rose from beside Kumoe. "Mireva?"

"It wasn’t copied badly."

Her voice had lowered. Rias stopped writing while Mireva stared at the lower relay.

"The timing was right. The return pressure was right. Every harmonic was where it belonged."

The map changed.

[Unknown Route Contact Established.]

[Lower Belfry Seal 4: External access request.]

Rias immediately opened a recording window while the young runner took one step backward. A second notice appeared.

[Sairren route-song recognized.]

Mireva stared at it. When she spoke again, there was no attempt to hide the fear in her voice.

"We never gave anyone that pattern."

Metal scraped somewhere far below them, and Mireva’s head snapped toward the floor. Another sound followed, slow and heavy. A locking mechanism inside the Lower Belfry began to turn.
