From the publisher:
For as long as mankind has sailed the void of the Jericho Reach, it has been a place of danger and mystery. Evil slumbers in the forgotten places between the stars, and only the Deathwatch can stand before it.
The Outer Reach is an exciting supplement for Deathwatch! Revealing the secret dangers that lurk in the darkness between the stars, The Outer Reach gives players and GMs never-before-seen access to the enigmatic Dead Cabal, a mysterious circle of warrior-scholars who have devoted their lives to fathoming the unfathomable. What’s more, this arcane tome presents the lost history of the arrogant and merciless Necrons of the Suhbekhar dynasty, and it offers the latest intelligence regarding their horrifically imminent return. All this, along with details on various Suhbekhar warriors, in-depth looks at the worlds beyond the reach of the Achilus Crusade, and scores of useful plot hooks, makes The Outer Reach an invaluable addition to any Deathwatch library.
