This is a playtest draft of IKEZU-ISHI (Malicious Rock), a feudal Japan inspired hack of Cairn. This document is a work in progress and will be updated with edits and additional comments. Any comments, suggestions, or feedback are appreciated and can be emailed to serialprizes@gmail.com.

While this supplement is inspired by Japanese mythology and feudal society, it is by no means meant to be a historically accurate text. Citing this in an academic setting will more than likely result in a terrible outcome, but if you want to play Samurai and hunt Yokai in Cairn then you’re in the right place.

Please feel free to treat any information in this book more as a guide than hard and fast rules. Many elements within this book are simply reskins of existing rules or NPCs in Cairn or other supplements for thematic purposes. Just as I have taken some liberties with the historical and mythical accuracy of some stats, you too can adjust any of these elements to fit your needs and game. Just be sure that all players are in agreement on any changes or adjustments before beginning play.

Feb 13, 2014 Update v0.2:
