#Drift of the Spirit Realm (靈界漂流記)

Contents

Drift of the Spirit Realm cover

A small kokunin domain has fallen into the Spirit Realm. One Barrier, one dying onmyoji, and you.

Expansion supplement — independent index. This is maintained separately from the core Konsei Reiyotan index.

This supplement assumes that the players and GM have fully learned every core rule from the core book(rounds/Energy/zones/squads/maneuvers/Three Ways and Six Hearts). First-time readers should read the core Introduction → Basic Axioms → Tutorial first, in that order.
