The "Shadow Realm" is a fictional dimension often depicted in various forms of media, including video games, movies, and literature. It is typically characterized by dark, eerie landscapes and is inhabited by shadowy creatures or entities. This realm serves as a place of mystery and danger, often contrasting with the brighter, more familiar world. In many stories, characters may enter the Shadow Realm to confront their fears or seek hidden knowledge. It is frequently associated with themes of duality, where light and darkness coexist, and can symbolize the struggle between good and evil, as seen in works featuring characters like Batman or Yu-Gi-Oh!.
