The Argentum is the intelligence agency of Thrane, and answers directly to the Council of Cardinals. It was originally founded hundreds of years ago as a branch of the Knights Templar dedicated to handling dangerous magical artifacts. Thrane's transition into a Theocracy during the Last War led to the Argentum being restructured to handle intelligence and counterintelligence responsibilities.
This change in focus from protecting Khorvaire at large from supernatural threats, to protecting the interests of Thrane, is contentious among members of the organisation. The addition of mundane threat management to the organisation's portfolio is seen by some members to be a distraction from their true mission.
Unlike many other intelligence agencies, the Argentum allows it's members to leave. Should an agent leave the organisation, or have their membership revoked, they are subjected to a geas that prevents them from divulging the organisation's secrets, but are otherwise free to leave and live the rest of their lives.
