A delicate mist, akin to a wisp of fog birthed from the chill of an unheated chamber, pervaded the space. A soft, bluish glow emanated from the vending machine, casting its light upon the pristine, polished tiles that lay beneath. In the hushed stillness of the bunker—a nocturnal sanctuary to which you belonged—you glided silently, attending to your nocturnal tasks, traversing the confines of this compact chamber.

It seemed an evening like any other, yet destiny harbored a twist unforeseen.

Cap, cap... Cap, cap...

A viscous, ebony substance descended upon you. Once, then again. Puzzlement gripped you. Craning your mechanical neck upwards, words failed to form... From the ventilation shaft, the appendages of a fallen comrade—a drone much like yourself—dangled lifelessly. Oil, rhythmically dripping from a punctured conduit above, kept time with the throbbing of your own mechanized heartbeat, amplified by the stirrings of dread. From the maw of the shattered duct, a metallic appendage emerged with grave, measured intent, clutching the tile's edge, and in its wake... The entity that followed defied easy description. A creature with the semblance of a gargantuan centipede wriggled from the slender aperture, its presence an enigma within the cramped confines.

"[Crawl]. [Crawl]. [Open]."

A voice, alien even amongst the robotic dialects, devoid of any vestige of life's warmth, emanated from the maw of the being... or what remained of it. Then, an entity resembling a head, akin to the drones yet bizarrely altered, contorted, and shattered, emerged.

"[Take a look]"

Was it describing its own actions for some reason? It fixed its gaze upon you...

"Light fare. [Salivation commences]. Host rejuvenation: a potential necessity. Compliance is preferred; resistance will only heighten our pursuit. Time to go into my mouth now. Yum yum"
