Pynnoci

Pynnoci is a fictional term used in speculative fiction and tabletop role-playing games to denote a class of memory-keeping systems—either physical devices, social practices, or both—designed to preserve and transmit knowledge across generations in an imagined world.

In some depictions, a pynnoci is a crystalline or glass-like device that records memories or learned data as light patterns or molecular configurations. Operators, called pynnocists, calibrate the device and extract memories for teaching or testimony. Pynnoci archives are often protected by codes or ritual seals to safeguard personal privacy and communal history.

In other settings, pynnoci refers to a ritual practice of preserving memory through communal recitations, performances, and encoded storytelling. Elders or designated memory custodians lead gatherings in which knowledge is passed to younger members through mnemonic structures, artifacts, and shared songs. The practice emphasizes accuracy, lineage, and consent in memory transmission.

The word "pynnoci" appears in multiple fictional languages and settings; its exact origin is usually unspecified within works, with authors treating it as a timeless concept rather than a real term. The concept is commonly used to explore themes of memory ethics, data ownership, and intergenerational responsibility, as well as tensions between privacy and communal knowledge.

Related concepts in fictional settings include memory palaces, oral tradition, digital archives, and memory crystals.
