From the rulebook's back cover:
CIRCLE OF HANDS is a stark, mud-and-dung Iron Age fantasy role-playing game about the Crescent Land, caught between the blinding purity of Amboriyon's cloud citadels with their deadly smiling envoys and the stained wastes of Rbaja with their stinking pestholes of undead.
[...]
Circle of Hands began as Gray Magick, my classic fantasy heartbreaker, and is now all grown up into bleeding, charred, smeared, and cruel perfection. That original 1990s manuscript is included in this book's final chapter.
