Uynml

A small creature that spends most of it's time flying, Uynml, sometimes called Kiteworms or Shriekkites, nonetheless sends shivers down the spines of any person unfortunate enough to run into one. Purple, hairless worm-like body of approximately three feet long with bat-like wings with membranes that have a distinct, wave blue pattern to them, which have a wing span of approximately five feet, while a single small claw juts out from the front of each wing. Two small feet with four clawed toes, clearly designed for gripping on rocky cliffs faces, the inside walls and ceilings of caves or the bark of trees. The rear of the creature has a thick tail, which is known to swell up after the creature has eaten a large amount of food. The head of the creature has three small, black eyes which shine faintly lime green in darkness, in addition the creature has  a pair of pointed, downwards curving large ears jut from just behind the eyes of the creature. It's mouth has two mandibles on either side of it, while the mouth itself is covered in sharp, shark-like teeth, when fully open the mouth appears to be jawless, and on the inside is a tongue with three mandible-like grabbing appendages on it's tip. The creature can be seen licking the air like a snake, as this is how it smells. Finally, but certainly not the least, just where it's head connects to it long neck, the creature has a pair of small horns, the purpose of which is unknown.

A terrifying predator of the night sky.
A deadly, fast flying predator, the uynml is clumsy and slow on the ground, but in the air, it is at it's element, as fast as a griffon or a dragon in flight, they soar high above the ground with their wings. They are primarily carnivores, but have been observed eating fruit from trees and mushrooms when it is safe for the to do so. Most active at night, the uynml gather in caves, the underside of cliffs or inside hollow trees by day. They avoid bright lights, and are especially afraid of fire, however they have been known to react with aggression when disturbed by torch-wielding travelers. 

Their bodies seem to possess a vitality beyond it's apparent frailness, as wounds close quickly and a lost limb will quickly regrow. This regenerative ability is combined with their ability to produce a small amount of lightning from their bodies, the exact method which they do so is subject to much speculation as their bodies tend to quickly decompose. By far their most terrifying ability, however, seems to be their ability to communicate telepathically with one another and other creatures around them. However, this where their lack of intelligence becomes apparent. as reports state that they have only ever sent simple message just as "danger", "intruder", "kill", "eat" and "move", suggesting that this telepathy is largely instinctual, thus not protruding to high cognitive functions.

Another of their abilities seems to be their magical ability to generate a psychic glare from their eyes, which has been known to stun and weaken the wills of their would-be attackers or predators. This ability however has a limited range as such they are not often seen using it.

Malicious, if a tab simple.

The sounds they make can simply be described as "highly disturbing", various sounds they make sounding like deep pained moans, until provoked at least, when they start making ear-piercing shrieks of anger and fury. A group of uynmls is thusly called a shriek. As aggressive they are, they can, barely, be controlled by a skilled ranger, probably due their lack of intelligence preventing them from being tamed or being taken on as companions.

Another key thing that has been noted about them is their maliciousness, as in they in particular seem to delight in the spilling of blood and tearing of chunks of flesh off from still conscious and alive victims. They have been known to use their ability to produce lightning to paralyze their opponents only to swoop in and start tearing of chunks of flesh in the most painful ways possible. This cruel nature seems suggest they are the creation of some twisted wizard or perhaps even a demon. The idea of "flying lightning spewing deathworms" certainly seems to fit the part. Simple-minded as they are however, their lack of focus on anything other eating, sleeping and reproduction, as well as the occasional bath of self-cleaning, does indeed make them more a kin to animals than anything else. This does not mean that they are not capable of surprisingly cunning tactics however, as they have been known to ambush parties of adventures or other groups of people, flying silently then suddenly attacking with a terrifying shriek. In general, if you detect a group of them, the best thing to do is flee in the other direction, and preferably, away from any dark spots, even though a singular one is not to be underestimated, as they have been the end of many a overconfident adventurer.
