Espionage and Intelligence in Khorvaire
"It's said the Last War was fought as much by spies as by armies." — Korranberg Chronicle
The Last War transformed intelligence work from a crown's luxury into a survival necessity. Every nation with the means to do so built networks of agents, informants, and covert operatives; every Dragonmarked House of consequence either ran one or sold access to one. When the Treaty of Thronehold ended open warfare in 996 YK, it imposed strict limits on standing armies, banned new warforged creation, and froze territorial claims. It said nothing about intelligence services. The omission was deliberate. Every signatory understood that the war of secrets would continue—it simply wouldn't require banners, declarations, or acknowledgment.
The Korranberg Chronicle calls what followed the Shadow War: a clandestine struggle among surviving agencies that has continued unabated in the years since the Mourning, just outside public view. The contested borders, collapsed institutions, and intelligence voids left by Cyre's destruction made Khorvaire fertile ground for this work. Where soldiers enforce policy through visible force, intelligence operatives rewrite the conditions that generate policy. Their success leaves no trace. Their failures become next week's scandal.
State Services
The major nations each maintain dedicated intelligence apparatuses, funded through national treasuries and answerable to their respective sovereigns.
King's Dark Lanterns (Breland) — The intelligence division of the King's Citadel, widely regarded as one of the finest agencies on the continent. Over 500 agents operate within Breland's borders; roughly a fifth that number work abroad. They answer ultimately to King Boranel ir'Wynarn, though field operations are coordinated by the changeling Captain Vron and regional knights marshal. Branch offices operate in Sharn, Starilaskur, and Xandrar, with a smaller presence in Stormreach.
Royal Eyes of Aundair — Aundair's intelligence service draws on the nation's deep tradition of arcane scholarship. Nearly every Royal Eyes agent operates with some magical advantage; the agency excels at divination, spycraft, and wand-and-dagger operations targeting rival nations and notorious criminals.
The Argentum (Thrane) — Originally a ministry of the Church of the Silver Flame tasked with acquiring and studying magical artifacts, the Argentum was repurposed during the Last War as Thrane's intelligence agency and has not reverted since.
The Dark Cabinet (Karrnath) — Created by Regent Moranna after the Shadow Schism severed Karrnath from the Serpentine Table of House Phiarlan. Karrnath's national reach was never fully restored; the Dark Cabinet fills the gap alongside House Thuranni's assassination work.
The Trust (Zilargo) — The secret police of the Triumvirate, the Trust is more deeply embedded in Zil society than any comparable agency elsewhere. Known domestically for maintaining order through an omnipresent web of informants and ruthless targeted elimination, the Trust is also active across Khorvaire—a fact that surprises most outsiders, who underestimate gnomish intelligence capabilities. The gnomes hold that knowledge is the greatest weapon of all.
House and Private Services
Dragonmarked Houses and independent organizations pursue intelligence for profit, house interest, or private ambition rather than national mandate.
Serpentine Table (House Phiarlan) — The covert intelligence arm of House Phiarlan, unknown to most outside the house and invisible even to many of its own lower-level operatives, who collect and pass information without ever learning how it is used. Phiarlan's entertainment networks provide unparalleled access to nobles, merchant lords, and closed rooms across the western Five Nations.
House Thuranni — Where Phiarlan produces the better spies, Thuranni produces the better assassins. Operating primarily in eastern Khorvaire from its headquarters in Regalport, the house has positioned itself as the preferred instrument for Karrnathi crown wetwork operations since the Shadow Schism. Baron Elar d'Thuranni rules the house, and is widely believed to have engineered the Schism himself.
House Medani — Through its affiliated Warning Guild, Medani occupies the counterintelligence and investigation end of the market: bodyguards, inquisitives, threat assessment, and the kind of discreet inquiry that powerful clients prefer not to conduct through official channels.
