Earthland

Earthland is a term used in science fiction, fantasy, and speculative fiction to denote an Earth-like world. It can refer to the actual Earth in a narrative that treats the planet as a setting, or to an alternate version of Earth in which history, geography, or biology differ from our own. The name combines Earth and land and is used to distinguish this world from other planets, realms, or dimensions within a story.

In practice, Earthland appears in various ways across media. Some works treat Earthland as a near-future or alternate-history Earth where familiar places exist but with distinct political, social, or environmental conditions. Others depict Earthland as a parallel or mirror world that coexists with another dimension or cosmos. Features commonly explored include recognizable landscapes and cultures, combined with speculative elements such as magical forces, advanced technology, or altered ecological rules.

Because Earthland is not standardized, its portrayal varies by author and project. The concept serves as a backdrop for exploring themes of global identity, cultural exchange, sustainability, and the human relationship with nature, while preserving a sense of familiarity for readers and players.
