The Ethereal Angler
Within the realm of the Endless Flesh, there exist many weird and violent organisms, most of them are predatory and, when not gorging on the gargantuan bounty that is their environment, they turn their attentions and their appetites on each other. Some develop defensive strategies that are very effective, and quite bizarre, and a perfect example of this is the Ethereal Angler.

Nestled like great blisters on the membranous walls of the Endless Flesh, many thousands of Ethereal Anglers soak in noxious, nutrient rich fluid, surrounded by torpid tadpole offspring, barely moving at all as they cast their mind out across the multiverse, hunting psychically for their prey.

Physically, the Anglers are nightmarish conglomerations of spider-like legs, crab-like eye stalks, squid-like tentacles and tremendous fangs unlike any earthly animal, all of this fronts a weak and bloated sack of organs which comprises the rest of it's body, somewhat akin to the slug-like abdomen of the Hermit crab.
One of it's front appendages ends in a bulbous, brain-like organ that allows it to project it's conciousness across the dimensional viel, seeking sentient victims.

Once the Angler finds a suitable being, it inserts a subtle psychic suggestion into the creature's mind, that compels it into performing an act of perversion.
This can be anything that would necessitate the target going off somewhere alone, with very little chance of anyone disturbing it.
When it gives in and acts on this unnatural craving, the Ethereal Angler strikes.

In the illustration, we see a farmer alone in his barn, about to do something very unsavory with his livestock, when there is a rending tear in reality and a horror from beyond bursts through, in a fountain of the foulest slime, great claws and tentacles lunge at the farmer and snatch him into fangs like elephant tusks, where he is quickly, silently dispatched and pulled back into the dimensional breach, to add fresh nutrient's to the Anglers cyst-like lair.

In the pool of slime that remains behind, most of the maggot-like offspring of the Angler will die, but one or two may latch onto nearby prey, and feed on them, in the manner of a leech.
After some time, they will burrow into the host and form a cyst of their own, going through many states of development, until they are strong enough to find the psychic signature of their own kind, and transport themselves across the dimensional barriers, to return to the Endless Flesh.
