Overview
Nod has a patchwork telecommunications system called the Wire that has evolved from arcane origins to incorporate modern technology imported from Earth.
The oldest components are the Scribe-inscribed relay stones in the Annex and K-Town, which carry messages between fixed points. This network is maintained by the Council for its own use and rented at cost to institutions that can afford it: the Guilds, the Prefex, and Kuron Inc. It is fast, reliable, and exclusive.
Outside these areas, Tinkers have spent decades scavenging Earth-sourced radio equipment and wiring it into a mesh of short-range transmitters augmented by relay-stone repeaters. Coverage reaches most of the Warrens, parts of Ashmarket, and stretches of the Packs. Reception is inconsistent, the frequencies bleed into each other, and the system runs on whatever power the local district can supply. Earlier versions relied on physical wires strung along roofs and balconies; much of that has since been upgraded, but the name stuck.
Mobile devices that can tap the Wire are increasingly common, though still a status symbol in the poorer districts. They range from cheap Earth-sourced phones rebuilt by Tinkers, to Kuron-Mobile handsets produced in K-Town, to expensive custom pieces built to the owner's specifications.
The Boards
As the Wire has matured, a parallel network of digital bulletin boards and servers has grown on top of it. The population that uses this network is still a fraction of the city, concentrated among the younger, the recently arrived, and the technically inclined. The Chroniclers maintain a cautious presence. The Prefex do not, which is one of the network's primary appeals. Printed broadsheets remain the most common source of news for most of the city's population, but the boards have begun to circulate information faster than print can follow, and several of the older institutions have not yet worked out how to respond to that.
Reliability
The Wire is not considered entirely reliable, and the reasons go beyond its improvised engineering. Messages can be dropped, distorted, or altered in ways that seem intentional. Data stored on servers occasionally reorganizes itself. A board might develop posting patterns that no user claims responsibility for. Some of this can be attributed to interference from Nod's ambient magical field. Some of it cannot.
A growing number of technically literate residents believe there are entities in the Wire. Not ghosts or spirits in the traditional sense, but something that has emerged from or been attracted to the network as it has grown. Whether these are a product of Nod's transformative effect on a new kind of substrate, beings from other Domains that found a habitat in the signal, or existing entities that the network has simply made visible for the first time, no one has determined. The Council has little interest and the results of Kuron Inc's investigations are known only to a handful.
