In anticipation of the release of the premium version of the Kaigaku RPG comes the Kaigaku Chronicle, a support magazine that fleshes out the game world. There’s lots of information for players and GMs alike, including new schools, adventure locations, NPCs, historical background, fiction and more. It's compatible with all OSR game systems, especially Black Hack, but has lots of useful information for any historical or mystery game.
