Darling's office was a chaos of movement and noise. Screens flickered with streams of data, graphs overlaid with layers of unreadable symbols, and an ominous pulsating wave that seemed to match the rhythm of his own heartbeat. Darling sat hunched over his terminal, his glasses smudged, his tie loosened, his fingers flying over the keyboard.
The harmonizer lay disassembled on the desk beside him, its scorched casing gutted to access its intricate core. Darling muttered to himself as he worked, the words half-formed, tumbling out like loose cogs from a malfunctioning machine.
In the corner, Trench stood with his arms crossed, his expression unreadable. He'd been watching Darling for hours, his patience wearing thin as the scientist buried himself deeper in his work.
"Darling," Trench said, his voice sharp. "Talk to me. What are you seeing?"
Darling flinched at the interruption, his head snapping up. His bloodshot eyes met Trench's, and for a moment, he said nothing. Then, as though a dam had broken, the words poured out.
"It's all connected, Director," Darling said, gesturing wildly to the screens. "The resonance, the anchors, the rift—it's not just a system. It's a signal. A transmission."
Trench frowned. "From where?"
Darling turned back to his screen, pulling up a map of the Oldest House overlaid with the resonance patterns they'd recorded. "At first, I thought it was coming from the anchors themselves. They're focal points, sure, but they're not the source. The signal is… external."
"External?" Trench repeated, his tone sharp. "Are you saying this is coming from outside the House?"
"Not just outside the House," Darling said, his voice trembling with excitement and fear. "Outside our dimension."
The words hung in the air like a thunderclap. Trench stared at Darling, his expression hardening. "Explain."
Darling spun his chair to face him, his hands gesturing frantically. "The resonance patterns aren't random. They're too precise, too structured. And when I filtered out the noise, I found… a code. A message. Someone—something—is trying to communicate with us. Or… invade us."
Trench stepped closer, his towering presence looming over Darling. "What does the message say?"
Darling hesitated, licking his lips. "It's fragmented, but I've pieced together enough to understand the intent. The resonance isn't just destabilizing the Oldest House—it's creating pathways. Dimensional bridges. Whoever's sending this signal, they're trying to open a door."
"A door to what?" Trench asked, his voice low.
Darling swallowed hard. "To their world. To their… reality. The rift in the Foundation was just the beginning. The anchors weren't just stabilizing the House—they were keeping it separate. And now, those barriers are breaking."
Trench's jaw tightened. "How long do we have?"
Darling shook his head. "I don't know. The signal is accelerating, and the resonance is growing stronger. If we don't stop it soon, the House will collapse—and take our reality with it."
For a moment, neither man spoke. The hum of the Oldest House seemed louder now, as though it, too, was listening.
Finally, Trench straightened, his voice steady. "What do we need to do?"
Darling hesitated, then said, "We need to trace the signal to its source. If we can find where it's coming from, we might be able to shut it down."
"And if we can't?" Trench asked.
Darling's face was pale. "Then we'll be fighting on their terms."
Hours later, Darling's breakthrough came with a flash of insight. The resonance wasn't just a signal—it was a map. The patterns formed a three-dimensional structure, a labyrinth of interconnected pathways that spanned dimensions.
Darling stared at the hologram on his screen, his breath catching in his throat. "Director," he said, his voice trembling. "I've found it."
Trench stepped forward, his eyes narrowing as he studied the projection. "What is it?"
Darling pointed to the center of the structure, a pulsing point of light. "The source. It's… an entity. A sentient being that exists outside our reality. The signal is coming from it, directing the resonance, breaking down the barriers between dimensions."
Trench's expression darkened. "And it's trying to come here."
"Yes," Darling said. "But it's not just trying to enter our world. It's trying to merge them—to collapse the boundaries entirely."
Trench's jaw clenched. "How do we stop it?"
Darling hesitated, his hands shaking. "The only way to sever the signal is to reach the source. But that means going… there."
Trench stared at the hologram, the weight of the revelation pressing down on him. "You're saying we have to cross into its world."
"Yes," Darling said, his voice barely above a whisper.
The room fell silent. Trench turned to face him, his expression hard but resolute. "Then that's what we'll do."
Darling blinked, his eyes wide. "Director, this isn't just another Threshold. We don't know what we'll find—or if we'll survive."
Trench placed a hand on Darling's shoulder, his grip firm. "We don't have a choice. If we don't stop this thing, there won't be a Bureau left to save."
Darling nodded slowly, his fear tempered by Trench's unwavering determination. "I'll prepare the equipment."
As Darling returned to his terminal, the Oldest House seemed to shift around them, its walls creaking and groaning like a living thing.
