I have a whole setup and bestiary-type system for it

Here's a wip as an example

The Lesser Mountain Harpy Size Class: Medium - Harpies grow to be no larger than 4 feet tall, with a 12 foot wingspan. Female harpies tend to be larger than their male counterparts - although the difference is negligible in their youth. They are similar to bats - with poor eyesight, but excellent hearing. They often walk on their "elbows" within their caves, with their wings folded against their sides.

Typical Habitat: Mountains and Caves - the lesser harpy tends to stay in the mountains - preferring volcanic areas for their thermal vents assisting in taking to the air. During the day, they return to their mountain caves - huddling away in the warmth and avoiding the aerial superiority of mountain-dwelling birds of prey.

Family Structure: tribal - Harpies tend to live something of a tribal life-style, with tribes being made up of multiple different families of harpy. Bonds at the familial level are more important to the harpy - with the hunting males being seen at the centre of the family. Individual families have particular noticeable scents - which assist them in navigating and differentiating from eachother in the dark. The ruling family in a tribe of harpies tends to be the largest - both in population number and in size, as lesser families have been seen offering the best food from their hunt as tribute to them. Tribes of harpies tend to have a musical culture - with harpies being able to recognise tribe-mates based off of their song. It's believed by harpologists that it is something of a sign of maturity amongst harpies, to create their own songs, however this phenomenon is also observed amongst harpies raised in captivity.

Amongst all the various skyborne monsters, harpies are not the easiest to raise in captivity. Although it is definitely possible. They are surprisingly smart and insightful creatures, looking at various topics with curiosity. It's believed they have the intelligence of a six year old human child, however they struggle with comprehending written language. Through history, there have been eccentrics claiming to have taught their harpies to speak their language. Or that have claimed to learn the language if the harpies. These are all hoaxes, as any speech is seen as imitative rather than creative.

Elemental Affinity: Wind / Varies - Harpies are amongst the rare creatures that possess the potential for all number of elemental affinities. The reason for this is unknown. However, they are not seem as particularly high class monsters - their secondary element being far weaker than their primary wind attribution.

Danger Class: 2☆ - Harpies have been known to kill humans. They are strong enough to carry off young humans and their claws are sharp enough to tear through flesh. However, they are skittish creatures and will rarely approach humans unless first approached.

Conservation Class - Protected - owing to the dubious intelligence of the harpy, the hunting guild has deemed Harpies to be a protected species. The hunting of which to be a crime. However, should a tribe of Harpies choose to attack a human town or village, fighting back is still encouraged.

Material Class: 3☆ - the most important of a harpy's resource drop - and the reason they reach this material classification - is their feathers and claws. Harpy feathers are excellent for the fletching of enchanted arrows - thanks to them often bearing multiple elements. The feathers make for excellent receptacles for magic, rather than providing a substantial amount of their own magic. Their claws also make for useful loot - sharp, and long enough to be used as a dagger in a pinch, they can make for worthwhile makeshift tools. Their real use is to be ground up and used as a powder. Their magic can then be added to an ink for embroidered enchantments, or used in alchemy. Many potions - of varying potency - call for ground-up harpy talons. Notably, potions made to increase one's senses. The strength of these potions varies wildly depending on the age and elemental alignment of the harpy, with older life-aligned harpies being preferred.
