A visual aid employed during tabletop role-playing games, primarily within the Dungeons & Dragons framework, designed to represent a subterranean environment intended for combat encounters. This cartographic depiction typically illustrates terrain features such as walls, chasms, and obstacles, alongside a grid or other system for tracking movement and positioning of player characters and non-player entities. For example, a game master might use such a representation to depict a winding cavern network where adventurers confront goblins guarding a treasure hoard.
Its importance stems from its ability to provide spatial clarity and tactical depth to encounters. By visualizing the battlefield, participants can make informed decisions about movement, positioning, and the use of abilities. Furthermore, these representations contribute to immersive storytelling, allowing players to better understand and engage with the game world. Historically, such tools have evolved from simple hand-drawn sketches to elaborately detailed, professionally produced maps, reflecting the increasing sophistication of the role-playing hobby.
