The Graybreakers are an international thieves guild that has operations on almost every continent on the planet, from its guild headquarters in Arcanum to the far reaches of the Dune Sea of Mamara.
Initiation
Members of the guild forsake their past identity for the surname "Graybreaker," giving their total allegiance to its unseen Operators in exchange for wealth, power, or status.
The Graybreakers are highly skilled and admittance into the guild is highly selective. To become a Graybreaker, an initiate must undergo rigorous tests of fitness, each of which has death as the consequence of failure. Once in the guild, there is no exit: those who try to return to their previous identities are hunted down and assassinated.
Inside the Guild
Graybreakers perform all sorts of jobs within the guild, from simple larceny and complex heists to smuggling treasure and performing assassinations. There exists a code of honor among Graybreakers that is recognized internationally, as well as a secret cant only members understand. Members of the guild abide by strict terms of engagement when dealing with other branches. Most Graybreakers aspire to become an Operator, but the identity of the Operators that govern the guild is the most well-kept secret of all.
Graybreakers and the Syndicate
Notably, the Graybreakers are considered to be a part of a larger "Syndicate," a world-spanning shadow government that represents the collusion between non-governmental corporate charters, merchant guilds, mercenary armies, and other independent organizations like the Retainers.
