An information broker's establishment in Chicago's Gold Coast, operating behind the facade of a rare book dealer, where the real currency is data and the clientele are people who need to know things that aren't publicly available. The Registry is run by a woman known as the Archivist — her real name is either unknown or irrelevant — who has spent two decades building the most comprehensive private intelligence network in the GLMZ. Membership requires a referral from an existing member, a vetting process that takes six weeks, and an annual fee of 10,000 Quanta. In return, members gain access to a private reading room where the Archivist will answer any question she can, broker introductions between members, and facilitate information exchanges that benefit the network.

The space itself is genuinely a rare book shop — the Archivist's cover is also her passion, and the collection is remarkable. The reading room is behind the shop, through a door that requires biometric confirmation, and it contains exactly what you'd expect: a comfortable room with good chairs, good lighting, and an encryption level that would make a military intelligence service envious. The Archivist doesn't trade in gossip or rumor — she deals in verified intelligence, sourced and cross-referenced, and her reputation for accuracy is the foundation of the entire operation. Lying to the Archivist is not prohibited by any rule; it simply results in permanent expulsion from a network that most members consider indispensable.
