Spiritin

Spiritin is a term used in speculative fiction and certain metaphysical discourses to denote a non-physical life energy that animates living beings and connects them to a broader spiritual or informational realm. In many settings, Spiritin is described as an essential vitality, capable of interaction with consciousness, memory, and emotion. The concept is often employed to explain phenomena such as healing, precognition, or spectral travel, with Spiritin represented as detectable only indirectly through effects rather than directly measurable by conventional instruments.

Definitions of Spiritin vary. Some writers treat it as a universal field akin to a physical energy, while others view it as a personal reservoir that individuals can sense, channel, or cultivate. In role-playing games and fantasy literature, Spiritin may be channeled through rituals, artifacts, or trained disciplines, and can be depleted or strengthened by practice, moral choice, or conflict.

Status and criticism: Spiritin is not recognized or verifiable by mainstream science; claims about its existence or properties are considered speculative or fictional. It is commonly used as a narrative device or world-building element to explore themes of life, agency, and connection beyond the material world.
