Lore — Myths, secrets, and the hidden history of the world
The lore refers to the body of knowledge, rules, and foundational elements that define a fictional universe. It encompasses everything that exists in the background of a narrative: the history of the world, its internal laws, beliefs, power systems, geography, as well as the invisible principles that ensure its coherence. The lore is not necessarily presented directly; it may be suggested, fragmented, or implicit, yet it consistently structures the world in which the characters evolve.
The term lore originates from Old English and literally means “knowledge” or “transmitted wisdom.” It was originally used to describe a collective form of knowledge, often oral, tied to traditions, myths, and foundational narratives. In the genres of fantasy, science fiction, and imaginary worlds, the word has become established as a way to describe this deep layer of information that gives a fictional world its depth and credibility.
Concretely, lore involves the construction of a coherent universe: the rules that govern it—such as the laws of the magic system or technology—the limits of what is possible or impossible, the origins of peoples, conflicts, or civilizations, as well as the internal logic that connects these elements together. It also includes recurring descriptions, historical references, value systems, and the invisible mechanisms that explain why the world functions in one way rather than another.
In a work of fiction, lore is not merely a backdrop; it forms the conceptual framework upon which events unfold, characters make choices, and the narrative evolves. The articles gathered here explore different aspects of this notion, examining how lore is conceived, structured, and used in fantasy and isekai universes, in close relation to worldbuilding and mythological foundations that give these worlds their depth.
This section brings together articles related to lore, focusing on how fictional universes are built, structured, and made coherent. The associated texts explore various facets of this concept, including rule systems, internal continuity, fictional traditions, and conceptual frameworks that serve as foundations for narratives.
