About & sources

Everything here is read from the files of Crusader Kings III itself — the script folders under game/common, game/history and game/events, and the localisation that gives things their names. Nothing is typed in by hand or written by AI.

Current data: patch 1.20.0.3 (Crozier), Steam build 25652598, read on 2026-10-02. When Paradox patches the game, the files are read again and every page updates. Each page names the file its numbers come from.

Content from every DLC is in the base game's files, so pages list it all. Effects that depend on a character, culture or faith are shown with the condition the game attaches to them.
