Prairieglass are horizon-born wanderers whose clans follow ancient routes across the open world. They read storms in the taste of the wind, remember distant places by the shape of their shadows, and treat every campfire as the temporary center of civilization. A prairieglass adventurer may be a clan outrider, a runaway heir, a sacred route-keeper, a trader seeking a lost homeland, or simply someone who has discovered that the horizon is not the same thing as the edge of the world.

Prairieglass are lithe, long-limbed beast-folk with powerful legs, narrow waists, and broad chests built for endurance. Their faces combine humanlike expressiveness with the features of swift grazing animals: mobile ears, broad nostrils, fine muzzles, and large reflective eyes. Every prairieglass grows a pair of hornlets or antler-like projections from the brow. These structures range from short swept-back prongs to elegant branching crowns, and their surfaces often become translucent with age, catching sunlight like pale glass. Their coats may be tawny, russet, cream, charcoal, brindled, or marked with geometric patches. Hair and mane textures vary widely. Some wear their manes braided with route beads, while others shave elaborate patterns into them. Prairieglass are warm-blooded, herbivorous omnivores with excellent balance and unusually efficient lungs. Their hooves, paw-pads, or split toes differ by subspecies, but all are adapted to long travel over uneven ground.

Prairieglass society is organized around traveling clans, seasonal alliances, and circles of trusted companions. A clan may include blood relatives, adopted outsiders, sworn partners, and the descendants of former enemies. Social status comes from useful memory, dependable action, generosity, and the ability to guide others safely through uncertainty. Their greatest festivals coincide with migration, foaling seasons, meteor showers, and the first rains. Music is carried by drums, reed pipes, throat-singing, and clattering ornaments worn around the ankles. Storytelling is both entertainment and law. A well-told account can preserve a treaty, expose a betrayal, or establish a claim to a disputed spring. Prairieglass children are encouraged to ask questions, challenge maps, and learn at least one craft that can be practiced on the road.

Prairieglass religion centers on the Three Vastnesses: Sky, Grass, and Memory. The Sky represents possibility and change, the Grass represents nourishment and obligation, and Memory represents the invisible road connecting the living to those who came before. Their shrines are usually circles of stones, braided poles, or polished horn fragments placed where the horizon is especially clear. They favor deities and spirits associated with travel, storms, animals, dawn, and ancestral counsel. Prairieglass cultures tend toward neutral and good alignments, valuing personal freedom tempered by responsibility to the clan, though an adventurer may follow any path.

Prairieglass homelands are defined by movement rather than borders. Clan caravans travel with collapsible wind-halls, low wagons, hide tents, and ribbed shelters that can be dismantled before sunrise. Permanent settlements appear near dependable springs or sacred hills, where stone foundations support broad, shaded courtyards. Buildings are low against the wind, painted in route-patterns that record old journeys. Their most important landmarks are not walls but standing stones, lone trees, watering holes, and ridgelines visible from many miles away.

Prairieglass are generally curious about settled peoples, though they often find fixed borders and inherited titles difficult to take seriously. They respect anyone who shares food, keeps a promise, or knows when to yield the road. Farmers and caravaners often value them as guides and weather-watchers, while city dwellers may mistake their directness for rudeness. Prairieglass clans have old rivalries with one another, but outsiders are expected to understand that these disputes are often conducted through elaborate races, competitive storytelling, and ceremonial bargaining rather than open violence.
