The Gutterglass Basin is a broad, rain-dark lowland where canals, ruins, workshops, and living architecture spread across several days of travel. It is the ancestral homeland of the Gutterglass, urban fey whose bodies echo the materials and visual language of cities. Prosperous trade districts stand beside flooded foundations and neglected alleys, creating a region where every road may conceal a market, shrine, feud, or forgotten entrance.
