Okuma's Guide to Gaijin
A homebrew supplement for the fourth edition, this guide updates material on the gaijin nations from earlier editions and expands on regions such as the Burning Sands, Thrane, and Merenae. It draws on published roleplaying books, novels, card games, and related setting references to provide background and descriptions for incorporating foreign cultures into a Rokugan campaign.
