Ratfolk
Ratfolk are Gildglade's most literal social mirror: creatures altered by Golden corruption until individual Memory gives way to the pack, then organized into subterranean markets, councils and a theology of the Swarm.
The City Beneath the City
Ratfolk are born from the same Golden ecology that Gildglade insists on calling prosperity. The formal taxonomy names the Golden Curse as their origin and describes bodies in which Time still functions but is distorted by Gold. Individual Memory is replaced by pack Memory; Function contracts toward survival; Will, in the strict table, is absent. The source summarizes the condition with a brutal phrase: formatted freedom. Ratfolk are not simply giant rats that learned speech. They are an example of what happens when a living system is made to remember collectively while every individual decision is bent toward the survival of the whole.
The urban description makes the metaphor physical. Rats beneath Gildglade breathed Golden Dust and gnawed Gold until, in the city's own joke, they learned to speak. Their colonies reproduce the city above: streets, markets and even a council. This is not incidental comic relief. Gildglade itself is a machine of appetite, exchange and collective ritual, and the ratfolk duplicate those forms without the polite language that humans use to disguise them. The joke that 'ratfolk are us, only more honest' works because their society exposes the same logic in stripped form: consume, bargain, organize, survive.
Their faith is the Prophecy of the Swarm. The Swarm is not described as a personal god but as collective Will, interpreted by Prophet-Alchemists in underground congregations. Its effects are practical: plague mists, poisons, voices that spread panic, tunnelling and sabotage. Military surveys estimate millions of ratfolk and emphasize that their danger lies not in the strength of one body but in the ability of a swarm and disease to consume a garrison without conventional battle. The Wars of the Dungeons with the molefolk make this hidden civilization impossible to dismiss; sometimes entire surface blocks collapse into conflicts already raging below them.
Yet the philosophical source contradicts the strict taxonomy in a productive way. The table says ratfolk have no Will; the Will-of-Errors chapter says they possess collective Will - a distributed greed in which each rat is part of a common hunger - and asks whether that is truly inferior to a human individual dissolving into a crowd. This conflict belongs in the Codex because it reaches the center of Aurelion's personhood problem. If Will must be individual, the swarm is a mechanism. If a choice can belong to a many-bodied subject, then the city beneath Gildglade may be a person on a scale the city above is unwilling to recognize.
