In "The Devil Colony" (2011), the SIGMA Force deals with mysterious nanotechnology that may have been mastered by an ancient Native American tribe, with input from the Manasseh. The team attempts to track down a lost map, journeying – among various farflung places – to Fort Knox and the grave of Meriwether Lewis. Rollins refers to secret codes used by Thomas Jefferson and Lewis. The coded message leads Crowe to John Trumbull's painting depicting the presentation of The Declaration of Independence.
