The Life Engine / Epochs
Epochs
The capability contracts that Worlds are built from.
What this surface promises.
An Epoch is a reusable historical or speculative capability contract. It defines the technology, institutions, professions, goods, transport, medicine, law, culture, language context, rights floor, and transition rules available to a World. Players choose a World; the World binds one of these contracts.
A person shaped by one era, a household across a complete life, or a lineage carrying memory into later generations.
Identity, time, health, relationships, money, property, work, organizations, reputation, evidence, law, politics, research, geography, NPC civilization, information, archives, moderation, and operations remain one platform.
Additional content packages deepen regions and eras through reviewed configuration rather than fragmenting the simulation into unrelated games.
Separately defines whether that World is a Continuum, Epoch Eternal, or Chronicle, how admission works, and how retirement becomes an archive.
Alternate History, Mythic, Supernatural, or Frontier mechanics can be added without replacing the Epoch contract or creating another codebase.
The World binds the Epoch contract, World Charter, and optional ruleset to its own isolated population, places, events, and permanent history.
World-building information
How to read an Epoch
- Contract version
- The revision number of an Epoch's capability rules. It changes when the actual era contract changes.
- Content package version
- The content edition of this Epoch’s playable material: professions, goods, institutions, technologies, places, and everyday details. It is separate from the game’s Alpha number.
- Validated package
- A ready foundation is complete enough for the game to load and use safely. Historical and cultural detail can still improve through expert and community review.
- Reference entries
- The included details across professions, resources, technologies, institutions, laws, transport methods, cultural notes, and regional variations prepared for this Epoch.
- World context
- The World using this Epoch as its historical foundation. An Epoch can support separate Earth, Aurelia, or Parallax timelines without merging their histories.
