From the publisher's website:
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 adventure in three parts for Deathwatch! 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. This epic campaign is told in three parts, and takes players across the Canis Salient and into midsts of the Hadex anomaly:
- The Depths of Treachery—The Kill-team travels to the iron heart of the Canis Salient to eradicate a subversive xenos presence imperiling the might of the Imperial war machine. But stirring in the chaos of sedition and catastrophy, they’ll stumble upon something much darker.
- Assault on Javar Nil—Pursuing clues of an ancient evil, the Battle-Brothers find themselves caught between the factions of a holy schism on the shrine world of Eleusis. There, they must safeguard the blessed core of the Achilus Crusade.
- Exterminatus—Struck at the very bastion of their power, the Kill-team must brave the horrors of the Hadex anomaly and return to a long-lost citadel to save their galaxy from utter ruin!
