The setting of Dungeons and Dragons, known as the Forgotten Realms, is incredibly vast. While many campaigns that take place in the Forgotten Realms are centered on the Sword Coast, the setting itself offers a wider continent and several other planes of existence. Such a massive setting can become overwhelming, even within campaigns that take place over hundreds of hours. One of the ways that stories like Baldur's Gate 3 manage this is through focusing on a small area, while bringing in lore from other parts of the world.
