"By the Emperor, Nicodemus, can you stop gloating for long-enough to actually do something?"
"Oh, sorry. Let me just use my 'blasphemous parlor tricks" to turn back time so that I can warn you not to go this way. Oh, wait, I DID tell you not to. Remind me again what it is you said."
"Nicodemus, we don't have time for this."
"I think it was something like 'We have no need for your blasphemous parlor tricks, heretic. I'm totally sure that just praying really hard and having ridiculous haircuts will save us from this entire horde of Tyranids that we just walked right up to.'"
Living ammunition slammed into the crumbling masonry that sheltered the psyker and three remaining Sisters of Battle. There must have been a few hundred assorted beasts arrayed against the dwindling squad, from a mob of lowly termagants to a pair of mighty carnifexes. The horde advanced slowly, unconcerned or possibly entirely unaware of the meager casualties they sustained from the sporadic bursts of fire from the Sisters' bolt guns.
"How were we supposed to know that that distress call was a trap?"
"I don't know, because I told you that I could sense no living humans, present company excluded, within thirty kilometers? Maybe because there was no way that anyone but the Emperor Himself could still be alive at the epicenter of the infestation?"
"For the love of the Emperor, will you stop complaining and put that warp-fouled brain of yours to use?"
"Of course, I'll just shoot them with my fucking mind bullets, why didn't I think of that? Oh wait, I'm a telepath, Sila. I can't do that. Would you like me to attempt diplomacy?"
Sila prayed for forgiveness as the psyker rambled and cursed. Two of her Sisters had fallen moments ago, presumably dead and digested. If she had just heeded Nicodemus' advise, they may well still be alive. She had been ordered to treat the psyker as one of her own, yet the Sister Superior allowed her zeal and ingrained prejudice to cloud her better judgment. Now, because of her incompetent leadership, they would all die in this Emperor-forsaken hive.
She took a moment to check on her remaining Sisters, confirming the precariousness of their situation. Atella was down to her last magazine and Mae, who had just been ordained a few days ago, looked as though she was on the verge of tears. Nicodemus, for his part, looked about as crazed as usual. As their leader, their lives were in her hands. She struggled to form a plan, but the weight of guilt and long-denied fear of death paralyzed her.
"Sila, I have an idea."
The psyker's voice snapped her back to reality, the noise of battle returning with a startling roar.
"With enough power, I can temporarily disrupt their synapses and throw the horde into chaos. They will still be dangerous, but they should lack the coordination to give organized pursuit. If we act quickly, we may be able to escape before they can reorganize."
"There are hundreds, if not thousands of them; there is no way that you have that much power."
"There are...certain methods I can use. It's not exactly safe, but-"
"You can't do that! If your powers go wild-"
"We die? Yeah, I'm pretty sure that that's going to happen either way. It's our only chance. I'm going to give you gals a head start, but I'm going to do it whether you run or not. You have five seconds before I start glowing and shooting fire out of my eyes."
With a nod, Sila and her squad took off as quickly as their power armored legs could carry them. Adrenaline and fear fueled their escape, though none could say whether the fear came more from the horde of ravenous beasts or the mostly normal human who was probably about to explode into a soul-searing fireball of otherworldly energy. She chanced but a mere glance back, her last sight of the psyker obscured by a growing ball of baleful purple light that cast unnatural, twisted shadows. At least that answered which she was more afraid of.
The Battle Sisters tore around the corner of the ruined street, desperate to put as much distance between themselves and the impeding disaster as possible. Their feet pounded the ruined pavement, the cratered and scorched ground shattering under their weight. Around them lay nothing but rubble, the aftermath of a week-long bombardment from the PDF's mobile artillery corps. Even without any discernible landmarks, Sila's auto-navigator plotted the fastest route to their predetermined rally point, 7.9km away and firmly inside Imperial territory.
They were probably well outside the range of the enemy's bio-sensors, but there was no reason to slow down. An ambush could come from anywhere at any time, particularly on the outskirts of battle where lictors and genestealers preferred to hide in wait. She scanned every patch of rubble, both with her eyes and her infra-vision sensors and knew that her Sisters were doing the same. No foe, visible or invisible, could approach from air or ground without their knowledge.
Each step brought them closer to safety, a mere 3.5km of open road separating them from their rendezvous point. Despite the relatively easy terrain, Sila briefly lost her footing, staggering forward as she reached out to her sisters to stabilize herself against their armored bulk. Her hands found nothing but air where she knew her squad mates to be, though that was soon to be the lowest concern on her mind. She was falling. Not to, but rather through the ground as she watched the road crumble and crater around her, sinking as though pulled down from below. The startled screams of her fellow sisters directed her vision straight down to something she would rather not have seen.
An enormous, spined biomorph hung below her, its chitinous talons grasping the edges of the hole through which she had just fallen. It was easily 30m long, its body twisted into hanging coils like a snake. Its maw splayed open, four independent jaws connected by skin-like webbing and covered in countless teeth. From its throat came a thick mass of tentacles, the longest of which were already wrapped around the legs of the other Sisters, pulling them in. Sila acted quickly, detaching her mag-locked bolt gun with practiced ease. She was not quick-enough, however, and found herself disarmed a moment later as grasping tentacles closed around her body.
The beast's grip was tight and offered no movement as the Sister Superior struggled to escape its grasp. As she was pulled closer, an ever-growing host of tentacles sought to restrain her movement, covering every available inch of her power armor until she saw naught but black. She had already seen her squad mates disappear into the cavernous maw, their ultimate fate shrouded by the horrific mass of mouth parts. At the very least, she knew that they had avoided the beast's teeth and hoped that she would be as lucky. If it intended to swallow them alive, perhaps she had a chance to cut her way out from inside. She would find her answer soon as she felt her legs pinned together by the creature's throat.
Inch after inch of her slid down the beast's slick throat, a crushing pressure she could feel even through the thick ceramite plates that protected her from an untimely death. Its grip tightened as her waist was engulfed, its strength matching against her armor's and coming up the victor. So great was the pressure that it became increasingly difficult to breathe. Her armor splintered and cracked under the creature's assault, her helmet's warning lights and alarms informing her of nothing she could not already feel herself. Her vision grew dark as she fought for breath, already ingested up to her chest. With her arms pinned by her side and the servos of her power armor burnt out, her last line of defense was sure to become her sarcophagus. With a final prayer to the Emperor, Sila closed her eyes and waited to die.
Her awareness returned slowly, as though intentionally hiding from her situation. Sila knew little more than that she was not yet dead, and that she did not seem to be in the creature's stomach. Her skin was wet but cool and definitely not being digested. A slight, pulsing breeze against her skin confirmed that she was now without her armor and likely entirely naked. Every inch of her body throbbed in dull pain, particularly around her waist and chest. A sluggish mental inventory told her that she had likely broken at least a few ribs, but her lungs still seemed to be working perfectly fine, even if breathing deeply was incredibly painful.
A strange, fleshy warmth engulfed her arms and legs, restricting their movement. She struggled briefly, though her broken ribs quickly reminded her of their presence. She was too weak to move much anyway. With some effort, she forced her eyes open, straining against both the darkness and her growing headache. Dim red light revealed a world of wet, pulsating flesh. Her arms and legs disappeared into the wall, spreading her limbs into a rough "x" shape, leaving only her torso and head free. To her left, she could barely make out the full-bodied form of Atella, similarly bound and still unconscious. To her right lay the still-maturing Mae, breathing slowly in her bindings. Sila let out a sigh of relief. At the very least, they were still alive.
"Sister Superior?"
A weak voice pierced the silence of the room, turning her attention to the opposite side of the chamber. A cold chill ran down Sila's body as her mind recognized the voice. This had to be Hell. She must be dead and just now realizing it. There was no other way she could be hearing that voice.
