Universal Culture

Sleep

Most Ptithian beds are round with circular pillows near the top placed in stacks, allowing them to raise their upper body and account for wing folding space and tails. There is also a tendency to have messy beds, with extremely poofy or fluffy blankets rather than sleek sets. Comfort and warmth are valued over a tidy aesthetic.
There also is no such thing as a "bed set", the whole "mattress cover, sheets, blanket, quilt, pillowcases, etc". A mattress is a mattress, and anything can be thrown on top of it to adjust for sleeping temperature conditions. Royals and rich will steer towards matching, aesthetically pleasing things though. Other sleeping arrangements include... on the floor, usually on a rug/ big floor pillow pile/ big bean bag/ hammocks/ lofted window cushion, etc.

Relationships

Although ptithians have unique cultures with their own relationship quirks, Ptitheros is still a highly connected world, and some relationship standards are shared globally. In general, ptithians do not have marriage nor do they propose. Instead, the transition from girl/boyfriend - fiancé - spouse, partner, etc., is based purely on time. The idea of having to sign a document to declare partnership is foreign and absurd to them.
Because there is no marriage, there are also no weddings. However, partnership celebrations still happen. These celebrations have no standard, the couple makes these parties into whatever they want.

Taboo

Any magic abilities involving flesh, such as blood or bone magic are considered taboo to the majority of Ptithians. Most monsters; vindiagos, windiages, phantom echoers, mokvels. Vampires and cannibals. Lindosts and all the parasitic, teeth, and eye symbology that comes with them.

Fame

There are famous/infamous names across Ptitheros, such as Vaia, an infamous monster hunter in the Wyndgale region. Royals and leaders are household names. There can be popular entertainers in a region who get hired more often because of the status, but Ptitheros does not have anything similar to classic celebrities, especially not in terms of lifestyle.
However, gossip about well-known names and past ones does circulate. Often local fame drives this banter, and it is not uncommon for rumors, good and bad, to make their way through those who enjoy stirring drama or form obsessions. With flight and callrunes, hearing gossip is hard to escape for anyone living anywhere besides the foreign wilderness.

Daily Technology

Ptithians use an array of aura-based technology in their daily lives. They do not live the classic medieval fantasy, instead, it is much more like an arcane sci-fi. From runes that regulate room temperature and fridges, kitchen appliances, GPS devices, energy storage similar to batteries, sound players and production, photography cameras, radios, and callrunes; a runic device that works like a highly simplified touchscreen system.
Callrunes are the most recognizable piece of newer technology. They allow video calling, voice calling, document storage of all sorts of files and messages, and can serve the purpose of older radios but can display a screen. Its only downfall is that everything must be real-time due to the nature of aura-signatures.
There are higher forms of technology, but they are not privy to daily use by the majority of Ptithians.
Ptithians have weights and obstacle equipment, treadmills and similar machinery too, but nothing close to computerized equipment, as all their technology follows a biohull, steampunk-y theme. Although, said exercise equipment would not be super common, particularly found on the space station and at training centers in cities for professionals. This is because Ptithians spend so much time outside and burn energy naturally simply living their life.
Scientific and artistic expos occur in the major cities. These expos display everything from upcoming technology, art galleries, book launches, relic and museum displays, scientific discoveries, and more.

Textiles

Fabrics for a variety of things include animal skin, leather, fur, wool, and all the usuals. Plus, plant fiber, leaves, cotton, silk, and various mixed materials made from the aforementioned items and extra agents (chemical or magic). Such as spacesuits, which are made from tampered windiage skin, chemicals, and enchantments. Ptithians are well-equipped to make many unique materials and alternatives to modern synthetic fabrics. As long as there is no plastic involved, as they do not make or use plastic in any way.
Because they never created plastics, all modern equivalent items that have use other materials. Fabric bags, glass containers, paper products, tempered animal skin, etc, there are many substitutes in their society and they are good at getting creative with the enchantments they have at their disposal.

Illness

Ptithians take illness seriously, doctors and anyone in the healing profession are valued highly because of how complex the information is when it comes to healing someone from any sort of ailment, both physical, mental, or arcanological. The specialties are often viewed as a triangle, as a healthy Ptithian is balanced between their physical health, mental health, and aura system health. Having one doing downhill can lead to problems in other corners of the triangle.

Economy

Ptitheros is a predominantly capitalist economy that stretches all kingdoms, creating a highly intertwined money system, workforce, and ease of transfer when it comes to working anywhere for any reason. There is no modern "big business", nor monopolies, only small businesses with the largest being the rare merchant family found in cities. Guilds can be argued, but they are mostly founder-funded or charity.
A large variety of occupations exist, many needed in all kingdoms, whereas some are more specialized. Jobs that require complex education are highly respected and artisans are valued for their skills too, as Ptithians believe natural talent is a myth and anyone is capable of being good at a skill with enough practice.
College is generally not expensive in Ptitheros, although some highly specialized education routes can get a bit pricey. When a kingdom needs more Ptithians in a specific occupation, education for said job is often offered for free/paid for by the kingdom in order to bring in those specializations.

Communication and Transportation

Ptithians have no trouble communicating long distances, not even space poses a problem. They have access to callrunes, radio lines, recorded sound, file transfer, and more.
Transportation is easy too. From flying routes and grounded trade routes all across the continent, snapp taxis, trustworthy mount companions, blimps, small and large ships, and even the occasional aura-train.

Recreation and Leisure

Time off and play is plentiful and necessary to have a happy society. Ptitheros is full of outdoor recreational activities and opportunities at leisure. From hiking, flight hiking, spelunking, various sports, gladiator battles, fishing, trophy hunting, rock hunting, mountaineering, skiing, and more. To accommodate the recreational activities, business pops up to provide places to stay and places to relax. From guided tours, hotels, lodging buildings, cabin sites, campsites, beach boardwalks and private zones at lakes, grottos, beaches and more. On-the-move "hotels" on blimps and trains are also a fun vacation option.
