Planar travel refers to the ability to move between different dimensions or planes of existence. In many fantasy settings, such as those found in tabletop role-playing games like Dungeons & Dragons, various planes can include realms like the Elemental Plane of Fire or the Shadowfell. Each plane has its own unique characteristics, inhabitants, and rules. Traveling between these planes often requires specific spells, artifacts, or portals. Characters may seek to explore these alternate realities for adventure, knowledge, or to escape dangers in their own world. Understanding the nature of each plane is crucial for successful navigation and survival.
