<P> Griffin McElroy served as the show's primary host and Dungeon Master for the show's first campaign, the Balance Arc . The campaign concluded with episode 69 in August 2017 . Following the wrap up of this three - year campaign, the McElroys decided to work on smaller "experimental arcs" in order to give themselves time to work on their next overarching story line . Each of these arcs takes place in their own game worlds separate from those explored in the other campaigns . The second campaign, Commitment, features Clint McElroy as the Game Master . The third campaign, Amnesty, has Griffin returning as game master . The fourth campaign, Dust, features Travis in the role of game master . </P> <P> There are two additional mini-arcs available to Maximum Fun donors . The first is "The Adventure Zone (K) nights", DMed by Travis, which features a steampunk - inspired world containing warring political and religious factions . Lin - Manuel Miranda guest starred in the second of the 2017 bonus episodes . The second is "The Adventure Zone Elementary", in which the group plays a fan - created one - shot RPG entitled "Four Sherlock Holmeses and a Vampire Who is One of the Aforementioned Sherlock Holmeses", which is DMed by Justin . </P> <P> Following Dust, the McElroys announced that Season 2 would continue the story introduced in Amnesty . </P> <P> Advertisements from corporate sponsors and paid messages from listeners, "Jumbotrons", are read by Griffin in the center segment of the program . Fans tweeting about the show using "#thezonecast" may be selected to become the namesakes for various non-player characters in the story lines . This trend has continued with the experimental arcs . During the Balance Arc fans could also suggest items to stock a "Fantasy Costco" for the characters to buy between quests . The Fantasy Costco has been partially revived in the Amnesty Arc to give fans a way to interact with the show . </P>
