Chapter 435: The Garden Beneath The City

Lily had placed the recovered container beneath three examination lamps. Aren hovered beside her, visibly impatient.

"Are you going to open it?" Aren asked, leaning over her shoulder. "Or explain every scratch on the lid first?"

Lily moved his hand away from the seal. "I identified the inventory mark yesterday. I promised Kai we would examine the contents together, not let you pry it open alone."

Kai arrived with Sera. "I see the morning has started peacefully."

"Very peacefully," Lily replied. "Aren has only asked me the same question six times."

"Seven," Aren corrected. "You ignored the first one."

Lily lifted the lid. Inside lay a circular metal plate with narrow teeth, the Aegis inventory mark, and a diagram of the Archive site’s lower foundations.

Kai bent closer. "A key?"

"An access plate," Lily explained. "It belongs to a maintenance chamber below the Archive. The entrance wasn’t listed on the plans we recovered from the main site."

Sera studied the diagram. "So somebody stored a key to a hidden room beneath a different building."

"The shelter may have been a supply station," Aren said. "Someone kept the plate without knowing what it opened. Nexus forgot what it opened."

Kai smiled. "Then we should find out whether the room is worth all seven of Aren’s questions."

...

The guarded Archive site admitted them through secured maintenance corridors, with permission from the Nexus Association. The isolated central network remained untouched.

Aren led them down an ordinary stone staircase. Cool air replaced the surface heat, and seamless pale stone replaced modern concrete.

"People walked above this place for generations without knowing it existed," Sera observed.

Aren ran his fingers along a faded marking. "That’s what I love about ruins. Every time someone says we’ve found everything, there’s another door."

Lily stopped at a circular recess in the final wall. She fitted the access plate into it and turned the outer ring by hand. Metal teeth clicked, and a heavy door slid aside.

Warm air flowed through the opening, carrying the scent of rain and flowers.

Kai looked at Lily. "That is not what I expected from a maintenance chamber."

Beyond the doorway, an enormous garden stretched beneath a ceiling so high that its edges disappeared into a haze of blue light.

Trees with silver trunks rose from islands of deep green moss. Their leaves shone in shades of turquoise, gold, and violet, casting moving patterns over the paths below. Pale flowers climbed stone arches, and long strands of luminous vines hung over still pools.

Above them, a transparent dome displayed a night sky filled with stars. A luminous moon drifted behind thin clouds. Though underground, Kai caught himself searching for the horizon.

A narrow waterfall descended from a terrace covered in white blossoms. It sent ripples across a pool reflecting the stars. As the water settled, the reflected constellations shifted into unfamiliar shapes, as though the garden were displaying a sky from another age.

Small metal birds perched among the branches. One tilted its head and released a clear, musical note. Others answered from across the garden until the chamber filled with a delicate chorus.

Aren stood with his mouth slightly open. "I’ve spent years looking through Aegis ruins. I’ve never seen anything like this."

Lily approached a tree, careful not to touch its leaves. "The lighting, irrigation, and temperature controls are still operating on independent equipment. This entire ecosystem has been preserved without relying on the central network."

Sera turned beneath the artificial sky. "They built somewhere beautiful just to keep plants alive."

Kai glanced at her. "You sound surprised."

"I imagined the Aegis only building machines and dangerous towers," Sera admitted. "Someone must have come here simply because they liked it."

She caught Kai’s arm and gave him a teasing look. "You know, this would have been an impressive place for our date yesterday."

"Should I apologize for discovering it a day late?" Kai asked.

"Only if you refuse to bring me back."

"Provided Lily doesn’t turn it into a research laboratory first."

Lily looked over her shoulder. "I can hear you. And I’m not putting a laboratory in the flower beds."

...

Blue stones lit beneath their feet. Ahead, two bridges appeared to lead to the same island, one much shorter.

Aren pointed toward the shorter route. "That should take us to the control pavilion."

Lily checked a small floor diagram beside the path. "According to this, it should take us to the eastern terrace."

Sera looked between the bridges. "They both end at the same tree. Unless the garden has a terrible sense of direction."

Kai tested the first step. The stones shifted, and the bridge seemed to lengthen.

Starbreaker’s Worldline Navigation identified the bridge’s existing connection to a side terrace, despite its misleading appearance. It could identify the route, not change it.

"The short bridge doesn’t reach the island," Kai said. "It bends toward the terrace. The longer one is connected to the pavilion."

Aren examined the seams and laughed. "Pressure-sensitive pathways selecting between local spatial connections. No wonder the bridges look wrong. They change where they lead when someone steps onto them."

Sera crossed her arms. "So even the garden wants visitors to take the scenic route."

They chose the longer bridge. A mechanical bird landed beside Kai, inspected his reflection, and chirped twice.

Sera smiled. "I think it likes you."

Kai offered it a finger. The bird ignored him, then flew straight to Aren’s shoulder and began tugging at the strap of his equipment bag.

Aren looked offended. "It likes my tools."

Lily laughed. "It has excellent taste."

...

At the pavilion, Lily found a preservation console still displaying its maintenance records. Her smile faded as she read the measurements.

"The recent ground movement damaged a circulation regulator," she said. "Water is draining from the eastern beds and collecting beneath the seed archive."

Through the glass floor, Kai could see a dark pool rising against rows of sealed storage cabinets. On the far side of the garden, several luminous trees were already losing their glow.

Aren checked the diagram. "The cabinets might withstand flooding. Those trees won’t survive without water."

Lily studied the console. "Resetting the pumps might erase the archive records. We’re not doing that." She looked toward the trees, their branches growing dimmer by the minute. "We can save both. I just need the manual channels working."

Sera looked toward the eastern beds. "Then tell us what to move."

Aren traced the water channels on the diagram. "There’s a manual sluice beside the lower pool. If we close it and open the gravity bypass, the water should return to the planting beds instead of the archive."

"The sluice is behind that damaged wall," Lily said. "Someone must hold its gate while I secure the bypass."

Kai rolled up his sleeves. "That sounds like something I can do."

Sera pointed toward a narrow access walkway above the lower pool. "I’ll take the other side. If the wall shifts, I can keep it from falling onto you."

Aren opened the service panel, and Kai braced against the heavy gate. Water pressed against the metal as he forced it toward its frame.

"Almost there," Kai called.

Sera caught a loose support as it slipped from the wall. "Then make it soon. This walkway isn’t getting any prettier."

Aren found the bypass wheel beneath a layer of mineral deposits. He tried turning it, but it refused to move. Lily knelt beside him and examined the locking pin.

"Don’t force it," she said. "The pin is holding the wheel against the pressure. Lift it first."

Aren adjusted his tool, freed the pin, and turned the wheel. Water rushed into a lower channel. Lily watched the console’s readings through her portable display and directed him another quarter turn.

The pressure against Kai’s gate eased. He seated it fully, and Sera helped lock the retaining bar into place. For a moment the mechanism shuddered, and Sera kept her grip on the bar until Lily confirmed the pressure had dropped.

The water stopped rising below the cabinets.

Water returned to the eastern beds. Dim leaves brightened, droplets gathered on the flowers, and the mechanical birds resumed their song.

Aren leaned against the railing, breathing hard. "I’d like it noted that we saved a garden without fighting anything."

Sera dusted off her hands. "You did fight a wheel."

"It was a remarkably stubborn opponent," Aren replied.

Lily checked the readings one last time. "The bypass is stable. We’ll need technicians to repair the regulator properly, but the plants and the archive are safe."

Kai looked around at the restored lights. "Then let’s make sure they stay that way."

...

The console released its catalog: botanical specimens, cultivation notes, environmental records, and Aegis inventories. Lily checked the backup copy against the original before letting anyone browse. She refused to risk a single page.

Aren read the headings with open delight. "Some of these records describe species nobody has identified in the ruins. There are cultivation instructions, too."

Lily began copying the catalog to an isolated storage device. "And environmental histories. We can learn what these plants needed without taking samples or disturbing the beds."

Sera watched a bird settle among the flowers. "I hope people can visit someday. Not everyone should need a research permit."

Kai looked at the benches beneath the trees and imagined visitors sitting under the artificial stars. "Once it’s safe, I’d like that too."

Aren scrolled farther down the inventory. His expression changed.

"There’s another section," he said. "Restricted storage, beneath the northern terrace."

Lily leaned closer. "What’s in it?"

Aren enlarged the entry. "An instrument assigned to Aegis field surveyors. The catalog lists it as preserved, but access requires a separate authorization."

Kai studied the marked location. Beyond the flowering paths, the builders had locked away something they considered important.

"Then we’ll start with the records," Kai said. "I want to know what those surveyors used it for before we open another door."
