Tabletop and digital game projects — tools, generators, and game frameworks.
Tabletop RPG rules and worldbuilding for the Mneme Cepheus Engine system and Under Heaven setting.


== [[Mneme_World_Generator|Mneme World Generator]] ==
== Under Heaven ==


A procedural star system and world generator built as a Progressive Web App (PWA). Designed for tabletop sci-fi RPGs, it produces scientifically grounded systems using recursive logic and dice-based mechanics.
Sci-fi setting covering humanity's expansion from Earth to interstellar civilization (2000-3000 AD).


The core philosophy is simulationist and modular: stellar formation, planetary placement, habitability, and civilisation development are each broken into separate procedural systems that feed into each other.
