because i need to make more of these, I guess.
Random info about various voidsent that I have been using in RP:

Colloquially known as “gnats”, the lowest order of voidsent resemble vilekin with horns and human-like teeth. They come in a range of sizes – mostly they are tiny, about the size of horseflies, but examples have been found that are the size of a fully grown chocobo. Gnats of all sizes manifest more or less spontaneously around concentrations of active void energy.

Puddings occasionally spring forth from places of immense filth and corruption. Though they have what amounts to a face, they are not sentient. They can, however, repeat sounds perfectly, including voices – more than one unwary adventurer has followed a friend’s cries for help in the darkness, only to find himself face to face with the blank eyes of a voidsent screaming in his friend’s voice.
Their tasty-sounding taxonomy was coined by an Ishgardian voidmath with an extremely peculiar sense of humor.

A common subject of the reverence of void cults all over Eorzea, mind flayers must be summoned into the corpse of a sentient being. The corpse undergoes a hideous metamorphosis, its head being entirely consumed and replaced by the mind flayer’s squid-like body, and regrowing any flesh it has lost in the process of decay. In general mind flayers are arrogant creatures – they seem to delight in the adoration of mortals and prefer to inhabit the bodies of kings and emperors.
The resemblance between the head of a mind flayer and certain kinds of earthly sea creatures is a hotly debated topic among scholars. Limsan academics, familiar with the horrors of the water, have proposed that voidgates open naturally deep within the ocean; an outlandish Sharlayan theory holds that squids and octopuses are simply the detached heads of actual mind flayers, grown feral and beastlike.

Atomoi are bizarre beings that appear only rarely in creation. Even among scholars of the void there is much superstition and very little solid information about them.
An atomos’s gaping maw is capable of swallowing anything small enough to fit inside it, and it is driven by a ravenous hunger that cannot ever be sated. When swallowed, the victim does not actually end up inside the atomos itself – thus its unending hunger. Instead, the atomos’s maw is a gateway to either absolute annihilation, or some kind of strange stasis-universe inaccessible from the outside. Some powerful voidsent use atomoi as living prisons for their most hated enemies.
It is possible that the phenomenon known as “Ozma”, which the Mhachi used to obliterate the city of Nym, is derived from research into the properties of the atomoi.
