Arks of Omen: Farsight is the fourth book in the Arks of Omen campaign event series for the 9th Edition of Warhammer 40,000.
At the end of a long and bloody road, the armies of the Farsight Enclaves stand poised to secure final victory over the Ork hordes. As Commander Farsight's audacious attack reaches a critical stage, an Ark of Omen and its attendant Balefleet erupt from the warp to shatter the balance of the conflict.
Thrown into a desperate fight for survival amidst a furious three-way war, the T'au are driven to take desperate measures. Their fighting retreat sees them forced to make planetfall on a world that O'Shovah vowed never to set foot upon again. With all other options exhausted, and foes closing in on all sides, the T'au begin a hit-and-run battle amongst the lifeless wastes and eerie ruins of Arthas Moloch itself.
Entangled by the galactic machinations of Vashtorr the Arkifane and his unholy servants, overrun by bellowing greenskin hordes and threatened by dark and insidious powers from beyond the veil, O’Shovah may face his final doom. Will aid reach him in time? Will the servants of the Dark Gods secure their diabolical prize? Or will this conflict reach an altogether darker and stranger end?
