The campaign is set within the world of a tabletop role-playing game known as Bunkers and Badasses, with Tiny Tina serving as a game master, sometimes deciding to modify the game world to add in a boss, an enemy or a NPC. The world is fantasy-themed, with skeletons, orcs, treants and dragons featuring as enemies, along with appearances by other Borderlands characters as residents in this world (such as Handsome Jack, who is portrayed as its villain, the Handsome Sorcerer).
