As the conflict against the Tau approaches its breaking point and paranoia over their suspected acts of sedition reaches an all-time high, the infamous Lord Commander Ebongrave seeks allies he can trust in his campaign against disloyalty. But are Tau sympathizers really maneuvering among the loyal citizens of the Imperium? And if so, what darker plans do they hold in store? Rising Tempest is an epic adventure in three parts for Deathwatch, the popular Warhammer 40,000 roleplaying game. When the Tau make a play for dominance that threatens to tip the balance of power in the Canis Salient, they'll unwittingly endanger the entire Jericho Reach... and only the Space Marines of the Deathwatch can stop them!
