Organized crime in the shape of the old courtly order. Not a resistance.
The Syndicate is organized crime — primarily fae and their mortal associates — that has replaced the old courtly order as the operating framework for unnatural society in the mortal world. It is not a resistance movement. It traffics in magical goods, artifacts, people, and lachryms: crystallized units of suffering used as supernatural currency. It causes real harm to the communities it operates in.
Where it came from
When the faerie courts fell — gradually through the 18th and 19th centuries, catastrophically in the 1940s — they did not vanish. Their old hierarchies, their patronage networks, their methods for moving artifacts and information, all of it survived in a more compromised form. The Syndicate is what those networks turned into once they could no longer rule openly.
What it trades
The Syndicate's stock-in-trade is anything the regulated economy cannot move: artifacts the Authority would seize, services no licensed practitioner will perform, people the system cannot or will not protect. Most prominently, it runs the lachrym trade — pressing operations, distribution networks, the illicit markets where larks change hands.
It does business with NextGroup. It is policed by the Authority. It does not fight the Unnatural Front and is not allied with them; the two organizations occupy adjacent niches and occasionally conflict over them.
The register
The Syndicate is not a sympathetic underdog and not a cartoonish villain. It is the form unnatural society took once forced underground, and like any shadow economy it both serves the communities that have no other recourse and predates on them.
