The Red Queen's assassins are on their tails as their small group of survivors flees through the maze of flesh. Lesser tentacled creatures scatter and hide, forewarned of the danger by the fear and pain coming their way.
Their group is a trio of tentacle-princesses, and a retinue of several of their smartest tentacle orbs, a handful of seducers, and lagging behind, a ball of floating flesh, undulating in terror.
One of the princesses looks behind her and shouts in a burst of psychic energy, "Talance, shink, you have to shrink! Smaller and faster! Hurry!"
The ball of flesh, the youngest among them, obeys, streamlining and catching up with the retinue. From how developed her mind already is, she is likely to develop into a proper changeling in time. If they survive.
There is a terrible rumbling, and a psychic scream of pain as the walls of the tunnel behind them suddenly rip apart in a magical explosion. The scream is deafening, explosions progressing up the tunnel in a rapid sequence. A massive deluge of blood, bone, and charred flesh collapses in on them... and just barely misses.
The passage is sealed off, with them on one side and the assassins on the other.
"Quiet," the tentacle princesses command in unison. "Let them think we're dead."
Even Talance is smart enough to understand, and close her mind down, hiding her psychic presence in the still-echoing scream of pain.
After enough time, they risk moving on. They can't go back, even if they could find the way, they'd just be killed. Tentacles find and penetrate orifices as the three princesses cling together in an orgy-huddle, passing the feeling of orgasm between them in a circle.
Up.
The only choice. These distant, unmapped reaches of the Red could sustain them, but if they're to have any hope of rescuing their lost lovers and companions from the machinations of the Red Queen, they can't just settle down here in these outskirts. The surface world is their only option.
Fleshcrafting a new tunnel that burrows up through the dead matter to reach sky will be the easy part.
