The Freemasons are a fraternal secret society, devoted to philanthropy and the spiritual development of its members. It is also a recruiting ground for the Guardians of the Veil, who use the layered initiations and rituals to gain influence over the Sleepers who participate in the organization, and to guide the Awakening of Sleepwalkers and potential mages.
For most Sleepers, Freemasons are simply a benevolent order devoted to charity, with some strange rituals attached. Some, though, find the symbolism and mysticism appealing and, if they are diligent and worthy, the Guardians guide them gently to other, deeper secret societies. This method seems to be fairly successful in recruiting the occasional Sleepwalker or new mage from the masses into the Guardians.
In Boston, the Freemasons are controlled mostly by the [[Emerald Scroll] cabal, though the Dead Wrens have started or taken over a few lodges for the The Free Council, leading to a divergent series of initiations and influences.
