Fibulus

Fibulus is a term used in speculative fiction and tabletop role-playing games to denote a class of fibrous constructs with applications ranging from materials science to bioengineering. There is no single canonical definition; different authors deploy the term to explore ideas of self-assembly, adaptability, and integration with other systems.

In technology-oriented settings, Fibulus fibers are depicted as modular, self-assembling strands that can form sheets, lattices, or conduits. They are often imagined to transmit energy or information, deliver medicinal payloads, and respond dynamically to environmental cues to repair damage or reinforce structures.

In biology-inspired narratives, Fibulus may appear as a filamentous organism or a living composite that grows by extending interwoven filaments. Such depictions emphasize themes of cooperation, resilience, and the convergence of biology with materials science.

Etymology: the name is likely derived from Latin fibulus, a small pin or rivet, chosen for its associations with fiber, connection, and assembly. In fiction, Fibulus appears across varied settings and is not tied to a single canonical source.
