Velkar had been beautiful once. You could still see it — in the arch of a half-collapsed gateway, in the spiraling filigree of a support column that had survived while the wall around it fell, in the way the ancient streets still ran perfectly straight despite five centuries of overgrowth pressing in from every side.
Now it was moss and shadow and the whisper of wind through broken towers.
Kael stood at the edge of the ruins and felt the Nexus Core hum against his chest. The Engine was responding to something here — an old signal, a resonance handshake from dormant Architect systems that hadn't been pinged in centuries. Through his visor, the whole site lit up like a blueprint, depth on depth on depth of hidden infrastructure still partially intact beneath the surface.
"There's so much still here," he breathed.
"Architect construction was designed for permanence," Omen said from his coat pocket. "They did not build for decades. They built for geological timescales." A pause. "The secondary depot is two hundred meters in, under what was once the civic center. There will be a staircase beneath a collapsed floor section — look for the hexagonal seal."
They moved in carefully. Lyra walked on his left, one hand in a ready casting position, her eyes tracking the shadows between crumbled walls. The storm charge in her ran higher here — something about the old magic embedded in Velkar's stones was interacting with her bloodline, her power singing against it like two instruments finding the same frequency.
"Do you feel that?" he asked her.
"Like coming home," she said quietly. Then, as if she hadn't meant to say it: "Which is strange. I've never been here."
"The Sigil responds to Architect sites," Omen said. "It was designed to. Navigation and access."
They found the hexagonal seal under a collapsed platform in the remnants of what had been a large open hall — civic center, as Omen had said, with the ghost of murals still visible on the standing walls. Kael placed his palm on the seal. The Engine pulsed. The seal lit up in the same cold blue-white as the sky event three nights ago.
The floor opened.
The depot beneath was pristine. Architect construction, sealed environment — the air that rushed up was stale but the contents were perfectly preserved. Kael descended into a space maybe twenty meters square, every wall lined with component storage: raw circuit-crystal, mana-battery cells, enchantment-weave fabric, micro-etching tools operating at tolerances he'd never imagined were achievable. In the center of the room, a single workbench with a terminal interface.
He could have cried.
"Take what you need," Omen said. "But be efficient. We have perhaps two hours before —"
The sound came from above. Multiple footsteps — heavy, coordinated, the specific rhythm of people who'd trained together. Kael and Lyra exchanged a look and went for the stairs.
There were six of them. Shadow-hulks — Malgrath's mid-tier infantry, human-shaped voids wearing enchanted plate that swallowed light, each carrying a resonance-lance that could punch through standard magic shields. They'd been waiting. Either they'd tracked Kael and Lyra to the ruins, or — worse — they'd known about the depot.
"Spread formation," Lyra said, already moving. "Don't let them bracket you."
The fight was nothing like the scout encounter in Velturn. These things were organized, intelligent, adapting. One of them hit Kael with a resonance-lance discharge that spun him sideways and scrambled his visor's display for three seconds. Another drove Lyra into a corner with coordinated lance thrusts, forcing her to spend energy on defense rather than offense.
But Kael had spent two days reading Architect combat schematics.
He triggered the pulse-glove at maximum frequency, which he'd never done before, and found that at full power it generated a radial burst wide enough to stagger all three of the ones converging on him simultaneously. He followed up with the grapple-line, not as a movement tool but as a weapon — the resonance hook discharged on contact, and when he yanked it back through the formation of shadow-hulks, it tore through their enchanted plate like it was paper.
Two down. He was sweating, his arm aching from the launch mechanism, but he was alive.
Across the hall, Lyra unleashed what she'd been building during the defensive corner — a compressed storm-burst that she'd been cycling tighter and tighter while blocking. It detonated outward in a controlled chain of lightning strikes that leaped between all three of her opponents in sequence, each bolt calculating the path of least resistance and finding it perfectly. The hall filled with the smell of ozone and burnt metal.
Six seconds of absolute silence.
Then Kael counted the unconscious forms. Six. He let out a long breath.
"You compressed that discharge," he said. "For how long?"
"About forty seconds." She was breathing hard. "I've never held it that long."
"That's terrifying and impressive."
"I prefer 'controlled and effective.'"
From his pocket, Omen said, very quietly: "Get back to the depot. Now. And take everything useful. We are no longer the only ones who know this place exists."
Kael grabbed every circuit-crystal cell he could carry. Lyra filled her travel case with enchantment-weave and several sealed modules she recognized from her grandmother's descriptions. They were back above ground in under four minutes.
As they left the hall, Kael looked back at the hexagonal seal, now closed again, the floor restored.
"They knew about the depot," he said.
"Yes," Omen said.
"How?"
A long pause. "Because they have someone who has been to a place like this before. Someone who knows how Architect caches work." Omen's voice was careful. "We should move faster."
They ran.
Behind them, at the edge of the ruins, a shadow stood against the setting sun. Too tall. Too still. Wearing armor that absorbed light like a wound in the air.
It watched them go.
Then it turned, and was gone.
