The "Syndicate" is a mysterious shadow government that is believed to oversee the dealings of various factions throughout the world. The degree to which the organizations involved in the Syndicate are beholden to its dictates is unknown. The following factions are known to have ties to the Syndicate:
- The Retainers, a company of treasure-hunting merchants;
- The Graybreakers, an international thieves' guild;
- A complex underworld of criminal organizations that reside in Cheapside in Arcanum;
- The Dread Legion, a faction of mercenaries who owe their allegiance to Mordaine and their lords;
- A slew of secret fences and arms dealers for the Empire of Arcadia and the servants of the Lords of Vanis, in both Nithaven and near its capital;
- Infiltrators from the Houses of the Changelings;
- Various political factions in Telrain that undergird its magic academies
Countless other smaller factions are also involved with the Syndicate's shadowy network. It's considered a dangerous position to be in if you have active ties to the network, as its tendrils are everywhere.
