Annals of Erthas

A living source of truth for creators, players, and curious readers.

This site, this Mundinomicon, unifies the canon of Erthas—anchored by the Teosiad cycle—with primary in-universe records (Chisei Nenki, Erthios Yairshrivin) and curated development notes into one organized, searchable home. Here you’ll find timelines, maps, cultures, languages, and style guidance kept consistent across stories, games, and music. Every entry tracks sources, canonicity tiers, and version history, so you can see what’s settled, what’s provisional, and what’s under active revision. Whether you’re onboarding to the world or building new material, start here to align with Erthas’s history, tone, and constraints—so the universe can keep growing without contradictions.
