The Peregrination is a simultaneously anarchic and strongly collectivist group. They're idiosyncratic and down right paranoid. Probably the largest isolated population of people in the solar system.
Vista Unlimited has both the money and materials to expand their Jovian settlement. What they don't have is the ships to carry it there. In an attempt to secure the use of single largest fleet in the System, their agent seeks an audience with the Peregrination. They've done the planning, detailed the budget, what they haven't counted on is that gaining the cooperation of the Family might require something more than ready cash.
