Gutterglass Rooks are clever city-dwellers who remember every road, rumor, and rooftop worth knowing. They build their lives in the vertical spaces others ignore, turning gutters into gardens, towers into neighborhoods, and discarded glass into family history. A rook adventurer may be a courier, investigator, exile, archivist, burglar, architect, or simply someone who has finally followed a mysterious route beyond the city walls.

Gutterglass Rooks are feathered beast-folk with expressive corvid faces, compact beaks, bright eyes, and hands capable of delicate work. Their bodies vary widely. Some are small and wiry, with long fingers and narrow wings folded along their arms. Others are broad-shouldered and heavy, with dense plumage, powerful legs, and short gliding membranes between their limbs. Feathers range from matte black and charcoal to blue-black, violet, green, silver, or white-flecked patterns. Many decorate themselves with beads, copper wire, colored glass, or ribbons that identify family and district. Their voices can be musical, rasping, or startlingly precise.

Rook society is organized around neighborhoods rather than bloodlines. A household may include relatives, apprentices, lodgers, rescued strangers, and beloved animals. Every district maintains a route keeper who records safe passages, blocked streets, local feuds, and places where help can be found. Rooks communicate with spoken language, posture, feather displays, rhythmic taps, and a layered slang called Rook Cant. Their festivals are nocturnal and architectural, featuring rooftop lanterns, choral mimicry, memory contests, and races through decorated alleys. They consider a person's reputation less important than the trail of obligations they leave behind.

Gutterglass Rooks favor practical household gods, saints of crossroads, spirits of rain, and ancestral figures associated with particular streets or buildings. Many leave offerings of polished glass, warm bread, or handwritten memories at public shrines. Their communities value mutual aid and personal freedom, so many rooks lean toward good or chaotic alignments, though ambitious civic leaders and exacting archivists are common exceptions.

Gutterglass Rooks thrive in old cities where towers, alleys, bridges, and market roofs create layered habitats. Their homes are narrow and vertical, with many entrances, concealed shelves, rooftop perches, and windows designed for watching the street. Rook districts often feature colored panes set into gutters or walls. These pieces are both decoration and civic record, marking births, deaths, disasters, treaties, and neighborhood boundaries.

Other peoples often regard Gutterglass Rooks as suspiciously observant, while rooks tend to regard everyone else as dangerously unaware of their surroundings. They are valued as couriers, scouts, translators, entertainers, investigators, and urban guides. Their reputation for theft is partly deserved, though most rook communities distinguish sharply between taking property and rescuing abandoned objects. Rooks are especially protective of overlooked workers and displaced families, but they can be wary of aristocrats, secret societies, and anyone who tries to control movement through a city.
