• What Doesn't Kill You Now Just Assimilates You Later
    Feb 20 2026

    A retired cop takes a security job at a classified desert research facility — and discovers something buried far older than humanity was ever meant to find. When a massive stone “wall” is excavated and brought inside, it begins to grow… and assimilate.

    After the story, we explore the real science behind biological assimilation — from deep-sea anglerfish that permanently fuse with their mates, to documented cases of human chimerism where two individuals become one body.

    What doesn’t kill you doesn’t make you stronger.

    It assimilates.

    Trigger warning: body horror

    (FYI: The name of the anglerfish’s lure is an “esca”.)
