No longer able to fight unaided, the still-living mortal remains of a Legions greatest warriors may be interred within a Contemptor Dreadnought to continue their service. A large number of these advanced Dreadnoughts were destroyed during the dark days of The Horus Heresy, but some survived and are still in service in the Space Marine Chapters and Chaos Space Marine warbands of the 41st Millennium.

This Contemptor Dreadnought has been marked with the icons and insignia of the Thousand Sons Legion. It may be taken in Legiones Astartes armies in Horus Heresy games using the rules presented in The Horus Heresy Legiones Astartes: Crusade Army List.

Contemptor Dreadnoughts can also be taken as part of a Space Marines army in standard games of Warhammer 40,000, for which the rules can be found in Imperial Armour Volume Two – War Machines of the Adeptus Astartes, Second Edition or in a Chaos Space Marines army, for which rules can be found in Imperial Armour Volume Thirteen – War Machines of the Lost and the Damned.
