Build campaigns that survive contact with players
A practical guide to designing, implementing, validating, reviewing, and playtesting campaigns for The Sovereigns Codex.
Field note 01
Learn with a complete campaign
The main tutorial builds The Drowned Bell, a short campaign that was validator-checked and thoroughly human-playtested. Each stage has a stable checkpoint and explains why the campaign data is shaped the way it is.
Field note 02
Know what each tool proves
The guide keeps contract support, validator results, runtime behavior, and human playtesting separate. A campaign can validate successfully and still contain an unreachable objective, confusing opening, or poor ending flow.
Field note 03
Move between learning and doing
Use the Guide to understand the system, the public Author tools to validate and import campaign data, and Play to test the result as a player.
