Agent Graves is the leader of a group known as "The Minutemen", a group of seven men (plus one "Agent") who serve as the enforcers and police of a clandestine organization known as "The Trust". The Trust was originally formed by the heads of 13 powerful European families who controlled much of the Old World's combined wealth and industry. The Trust made an offer to the kings of Europe by which they would leave the continent and their considerable influence and holdings, in exchange for complete autonomy in the still unclaimed portion of the New World. When England ignored this proposition and colonized the Roanoke Island late in the 16th century, the Minutemen were formed. The original Minutemen, seven vicious killers, eradicated the colony and all of its inhabitants, leaving behind only the cryptic message "Croatoa" as a warning, reclaiming the land for the Trust. Since this time, the Minutemen's charge has been to protect the 13 Houses of the Trust, serving as their force against outside threats and more frequently as police of the internal conflicts between the Trust families themselves. The groups' interactions are often facilitated by a person holding the title "Warlord" for the Trust, who serves as the Houses' liaison to the Minutemen.
