Gutterglass are the fey of crowded streets, forgotten stairwells, rooftop gardens, and all the secret agreements that let a city endure. They remember which baker feeds stray dogs, which alley echoes before danger arrives, and which locked doors are only pretending to be locked. Curious, stubborn, and difficult to surprise, they turn urban life into a living web of omens, favors, and hidden paths.

Gutterglass are urban fey whose bodies combine mortal substance with the visual language of the city. Their skin may resemble soot-dark stone, rain-polished brick, pale plaster, copper patina, or colored glass. Their eyes reflect nearby signs, lamps, stars, and faces even in darkness. Hair commonly grows in textures like wire, moss, ribbon, smoke, or fine spun metal. Some have pointed ears, tails, small horns, antlerlike branches, or translucent patches, but no single feature is universal. Their size varies dramatically among family lines. Clothing is practical, layered, and heavily personalized, often incorporating keys, brass buttons, ticket stubs, charms, pockets, and fragments of old maps.

Gutterglass culture is organized around neighborhoods, guilds, chosen households, and the keeping of useful stories. A person's reputation matters more than their ancestry, but ancestry remains visible through inherited tools, local accents, traditional colors, and family routes. Children are taught to read signs, recognize safe houses, mend common objects, and distinguish a genuine warning from ordinary bad luck. Hospitality is sacred, though it may be offered in unconventional forms such as a dry corner beneath a bridge or a password to a guarded courtyard. Their disputes are settled through witness circles, public repairs, exchange of favors, and occasionally elaborate contests of memory.

Gutterglass rarely worship distant gods in formal temples. Most honor household spirits, ancestral founders, sainted builders, old rivers, crossroads, and the mysterious intelligence they believe exists within every well-loved city. Their ceremonies involve sweeping thresholds, lighting lamps, ringing bells, planting window herbs, and sharing food with strangers. They are often neutral or good, valuing community and mutual obligation, but individual Gutterglass may become lawful through devotion to custom or chaotic through a lifelong resistance to imposed order.

Gutterglass communities occupy the overlooked seams of civilization: attic walkways, sealed courtyards, disused stations, bell towers, market tunnels, rooftop gardens, and rooms hidden behind false walls. Their architecture favors adaptable spaces that can be rearranged overnight. Doors are often painted with symbolic scenes rather than numbers, and windows are made from colored glass, polished bottle shards, or sheets of enchanted rain. A Gutterglass district is rarely governed by a single ruler. Instead, guilds, resident circles, street spirits, and elder households negotiate through custom, favors, and public ritual.

Gutterglass judge people by how they treat shared spaces and vulnerable strangers. They often form close partnerships with mortal guilds, street performers, couriers, innkeepers, gardeners, and repairers. They are wary of aristocrats who claim ownership over entire districts, though they may respect nobles who understand stewardship. Other fey often see them as too entangled in mortal concerns, while mortals may mistake their local knowledge for mere cleverness. Gutterglass friendships are loyal, practical, and full of reciprocal obligations.
