Official Synopsis
Even as the Imperium faces the renegade Legions of the Warmaster, the ruling Council of Terra is becoming paralysed from within by increasingly petty bureaucracy. Fabricator-General Zagreus Kane has seen his fellow Mechanicum adepts dismissed again and again by the High Lords – with his traitorous predecessor Kelbor-Hal still at large on the Red Planet, the political status of the tech-priesthood remains ambiguous. New alliances must be forged from the old, if Mars and Terra are to survive the final battle.
