Let's face it, Rokugan isn't exactly the most peaceful place ever. While there are certainly times of piece, the different Houses tend to fight a lot against one-another. The Fields of Victory book for the Legend of the Five Rings RPG focuses on warfare across the land with a particular focus on the Lion Clan. If you're looking for an adventure to go on, you'll also want to check out the Blood of the Lioness. As the title indicates, the Lion Clan plays a big role here as well.
From the article:
Throughout history, Rokugan has been no stranger to war. While the Great Clans have served the Empire faithfully for centuries, they have been at odds with one another as often as not. Although generations have come and gone since the time of large-scale wars between clans, many useful things can still be gleaned from their history. If Rokugan ever finds itself thrust into the chaos of another war, the generals of the Great Clans will find the military knowledge of their forebears absolutely invaluable.
Fantasy Flight Games is excited to announce the Fields of Victory sourcebook and the Blood of the Lioness adventure for Legend of the Five Rings Roleplaying!
Fields of Victory contains three chapters overflowing with information about warfare in Rokugan, both past and present, as well as providing new gameplay and character-building options for players. The valiant Lion Clan has always taken great pride in their study of history, including their methods of preserving it, and so much of the information about famous Rokugani battles of the past is presented from the Lion Clan’s perspective. This book provides Game Masters with an arsenal of supplemental rules, tools, and guidance for staging grand battles in their own campaigns; meanwhile, players receive new character options through the introduction of the Badger Clan, ten new schools, and a variety of new titles and techniques to expand on existing player characters.
Once you’ve familiarized yourself with Rokugan’s traditions of warfare, you and your group can tackle the new Blood of the Lioness adventure. This exciting tale takes you and your fellow samurai from the iconic Akodo War College to a heated battlefield on Snow Plain, and the actions of your party could help protect the peace in Rokugan—or plunge it into the chaos of war.
