The coldly methodical and unrelenting Iron Hands Space Marine Chapter clash with the cybernetic soldiers of the Adeptus Mechanicus over control of the world of Thennos.

Ever since the dark days of the Great Heresy, the Iron Hands have a long and tortured history. Their years of suffering and war has left them hardened and believing in a brutal tenet: the flesh is weak. Heavily cybernetic, their flesh extensively altered, these warriors of the Imperium are more machine than man, cold in aspect as well as demeanour. Their methods of recruitment are harsh, their rituals arcane, their pride unshakable. So when a world under the protection of the Chapter falls foul of insurrection, the Iron Hands answer with fire and cold retribution. It matters not that Thennos is considered sovereign territory by the Adeptus Mechanicus - the Iron Hands' campaign is one of extermination. But there is something dark lurking within Thennos, a horror that defies the purity of cold logic and the machine, and threatens something more, something ruinous...
