Welcome to the Jade Empire.

The Emperor Toturi has ruled Rokugani for two years of peace, but that peace will soon be shattered. When the Emperor vanishes from his bedchamber, accusations and speculation fly. Old hatreds boil to the surface. Before long, the clans collide once more in a war that threatens the Empire.

And in the shadows of Mori Kage Castle, Goju Adorai makes his plans. A force older than the world itself prepares to twist all of creation to its purpose. The time has come, and at last it has the tool it needs to turn Rokugan against itself.

At last it has an Emperor.

Within The Hidden Emperor you will find the following:

• A complete and updated history of the War Against the Darkness, retelling the story of the Jade Edition story arc of Legend of the Five Rings. Old tales are retold for posterity, and new mysteries are revealed.

• New mechanics and adventure hooks dealing with this period in history, but that can be easily adapted to a campaign set in any time period.

• A complete campaign set in the War Against the Darkness.

• Updated statistics for over forty of the most important personalities in this era.

This book is a dual-system supplement for the Legend of the Five Rings Role-Playing Game, Second Edition, and Rokugan, the d20 Companion for Legend of the Five Rings. Players and DMs may also find it useful as a source of interesting new feats and abilities for any d20 System campaign.

Dungeon Masters running d20 System games will need a copy of the Player's Handbook, the Dungeon Master's Guide, Oriental Adventures, and Rokugan. Players will need only a Player's Handbook.
