Gutterglass are the quick-handed citizens of the overlooked city, a people of attic paths, cellar doors, rooftop gardens, and whispered favors. They know which baker leaves out yesterday's bread, which watch officer can be trusted, and which ancient tunnel still runs beneath the courthouse. To outsiders they may seem suspicious, fussy, or perpetually distracted. In truth, Gutterglass understand that cities are living creatures, and survival depends on noticing when one small thing has gone wrong.

Gutterglass are compact beast-folk with rounded ears, expressive whiskers, nimble hands, and coats ranging from soot-black and russet brown to cream, silver, brindled gray, and mottled gold. Their features suggest a blend of small urban mammals, most commonly martens, civets, raccoon-like climbers, and long-bodied alley hunters. Their eyes are large and reflective, their teeth are sharp but unobtrusive, and their tails vary from sleek and tapering to broad and ringed. They dress for movement, favoring layered vests, soft boots, hidden pockets, and bright scraps of cloth that identify neighborhood, trade, or family affiliation.

Gutterglass society is organized around households, block associations, trade circles, and neighborhood councils rather than distant rulers. A household may include blood relatives, married partners, apprentices, retired elders, and friends who simply needed a place to stay. Hospitality is treated as a practical duty, but it comes with expectations: guests help with chores, respect household boundaries, and contribute what they can. Children learn local geography through games, songs, and supervised errands. Adults exchange favors through an elaborate system of courtesy tokens, written promises, and remembered debts. Their festivals celebrate repairs, new businesses, safe returns, and the opening of public spaces. The most serious social accusation is not dishonesty but abandonment.

Gutterglass religion is domestic, civic, and ancestral. They honor hearth spirits, patron saints of trades, the remembered dead, and personified virtues such as Shelter, Fair Measure, and the Open Door. Some leave offerings beneath bridges or at crossroads, while others maintain tiny shrines inside cupboards and chimney niches. Their communities tend toward lawful or neutral traditions because agreements, schedules, and shared responsibilities keep crowded neighborhoods alive, but individual Gutterglass may be compassionate rebels, ambitious opportunists, or fierce defenders of personal freedom.

Gutterglass communities occupy the overlooked spaces of cities: attic walks, disused cisterns, bridge chambers, cellar streets, and narrow homes built into the backs of larger buildings. Their architecture favors layered access, shared courtyards, foldaway furniture, rooftop paths, and doors that can be opened from either side. A proper Gutterglass home contains several ways out, not because its occupants expect disaster, but because a city is always changing. Public spaces are bright, communal, and meticulously maintained, while private rooms are often compact, warm, and full of labeled drawers.

Gutterglass are woven into the life of almost every large settlement, though they are rarely the people depicted in official histories. They serve as messengers, shopkeepers, archivists, repairers, guides, cooks, investigators, and caretakers. Many other peoples regard them as dependable neighbors, while wealthier citizens sometimes mistake their communal customs for servility or assume that every Gutterglass knows every secret in the city. Gutterglass maintain strong ties with humans and other adaptable peoples, trade extensively with craft-focused communities, and are often wary of aristocracies that treat neighborhoods as disposable.
