Chapter Two: The Echo of Distant Thunder

The bunker smelled of ozone, sweat, and the thin, copper tang of old blood. Vox-Officer Tamm sat hunched over his console, fingers dancing across the cracked keys, coaxing life from the dead air. The only light came from the flickering runes of his panel and the distant glow of fires eating the underhive. Outside, the city screamed. Inside, Tamm whispered into the void, a prayer on a stolen frequency. Sergeant Vela Kross ducked through the doorway, her lasgun slung across her back. A fresh gash ran from temple to jaw, sealed with field glue. She looked at Tamm, then at the mute speaker grille. "Anything?" Tamm shook his head, not pausing. "The Secundus signal died an hour ago. But I heard something else. A ghost. A pattern." "A pattern?" Kross moved closer, peering at the oscilloscope. "Not Imperial. Not xenos either. It was… rhythmic. Like a heartbeat." He tapped the console. "I think it's a Navy long-range burst. Scrambled, but real." Hope was a dangerous thing in a besieged hive. Kross had learned that twelve years ago, on a mud world where hope had been a slowly leaking wound. But she saw the light in Tamm's eyes—the same light that refused to die. "If it's Navy, they're not coming here. They're running for the Mandeville point." "They might relay," Tamm said stubbornly. "Someone has to hear. Someone will remember." A low rumble shook the bunker. Dust trickled from the ceiling. Kross grabbed for her lasgun. "That wasn't artillery. That was something closer." Seconds later, a ragged corporal burst in. "Sergeant! They've breached the secondary barricades! Xenos in the chemical tunnels—they're heading for the hab-domes!" Kross was already moving. "Tamm, keep the signal alive. If we fall, you're the last voice." She didn't wait for a reply. The corridor outside was a half-lit nightmare: bodies piled against sandbags, las-bolts trading with claws in the smoke. Kross took her squad—what remained of them—and pushed into the tunnels. The genestealers moved like oil through water, fast and silent until they struck. She emptied a clip into a screeching creature, its limbs scything through her closest trooper. The fight was a blur of sound and blood. Back in the bunker, Tamm heard it through the static: a voice, faint, clean, laced with interference. "...this is Navy frigate *Steadfast*… hailing any Imperial assets in Hive Tertium…" His heart slammed against his ribs. He keyed the vox, his voice cracking. "*Steadfast*, this is Hive Tertium, vox-officer Tamm. We are under siege. Genestealer uprising. No reinforcements. It is—" A crash behind him. The bunker door buckled. "—it is an honour to serve the Emperor!" He shouted into the mic, even as claws splintered the steel. "We held the line! Tell them we held!" The door burst inward. Genestealers poured through the gap. Tamm grabbed a laspistol from a fallen guardsman, fired twice, and reached for the vox again, his last words swallowed by static as a talon pierced his chest. But the signal kept transmitting. And somewhere in the void, the *Steadfast* recorded a fragment: *"…we held…"*
