Set in a galaxy-spanning, far-future empire dominated by noble families, secret societies, and intractable trade guilds, the Dune trading card game thrusts players into a malestrom of shifting alliances and hidden agendas for wealth, status , and a seat on the all-powerful Landstraad High Council. Judge of the Change is the first three-month story based expansion arc, following the original Dune novel written by Frank Herbert.

First light glints wanly off the dull metal of the newly arrived House frigates. A drum corps pounds a tight cadence as the new governor and his family emerge to regard Arrakis in the morning light. By midday the fanfare reaches its crescendo, the vigor of its celebration vainly fighting against the dizzying heat of the merciless Arrakee sun. It is an historic moment in Arrakis, the time of a new regime, a time of change and a time of judgement...

Every governor must strike a bargain with the Spice Miners Guild if he hopes to meet his quota and keep his house in the good graces of the Padishah Emperor and the Landsraad Council. The Atreides are no different. Duke Leto's first move as the new governor is to earn the respect and calm the fears of experienced spice men who know all too well the dangers of aiding a sworn enemy of Baron Vladimit Harkonnen.
