For example, picking Khorne will make you unable to use Noise Marines, while picking Tzeentch makes you unable to use Nurgle units and vice versa. You can only pick one Mark and picking one will make you unable to access the units of another god. You dedicate your army to a god by selecting one of the four Marks. Chaos Marines can also choose to dedicate themselves to a single Chaos God to unlock specialized units and upgrades. Just like Loyalist Astartes, Chaos Marines are quite expensive to train and reinforce, so it's a good idea to have a stable economy. Pleasure, wealth, but above all else the power to rule their fellow men in the name of the Chaos Gods, is the driving ambition and goal of every Chaos Space Marine.Ĭhaos Space Marines are similar to Space Marines in that they have similar troops and vehicles but aren't as flexible and more geared towards close combat. Chaos Space Marines fight for everything they were once forbidden to indulge in as the ascetic servants of the Emperor and the selfless guardians of Mankind. The flesh and Power Armour of Chaos Space Marines often warps and twists into new, darker and inhuman forms under the influence of the Chaos energies they are exposed to, as their shapes morph to embody the corrupted Astartes' new allegiance. Meanwhile, the Black Legion, the Night Lords, the Iron Warriors, the Word Bearers and (possibly) the Alpha Legion serve Chaos Undivided. The Emperor's Children serve Slaanesh, the Death Guard serve Nurgle, the World Eaters serve Khorne and the Thousand Sons serve Tzeentch. The Traitor Legions either dedicated themselves to a single Chaos God or Chaos Undivided, although no one knows in the Alpha Legion's case. They are the Black Legion, the Emperor's Children, the Death Guard, the Iron Warriors, the Night Lords, the Thousand Sons, the Word Bearers, the World Eaters and the Alpha Legion. The nine original Traitor Legions are the most powerful of the Forces of Chaos. The traitors fled into the Eye of Terror to escape the Imperium's wrath, where they reside to this day.


After nine gruelling years of war, the Imperium eventually triumphed at the Battle of Terra, where Horus was obliterated and the Emperor mortally wounded. The traitors were led by Horus Lupercal, the Emperor's most favoured son and Warmaster of the Imperium. Chaos Space Marines are proof that not even the Emperor's Finest are immune to the seductions of Chaos.Ĭhaos Spaces Marines originated in the Galaxy-wide civil war known as the Horus Heresy that saw nine of the eighteen Astartes Legions turn away from the Emperor's light, led by their Primarchs. Traitor Astartes either belong to one of the 9 Traitor Legions while other traitors come from Space Marine Chapters that have turned Renegade. A Chaos Space Marine, also sometimes called a Traitor Marine, is a formerly loyal Space Marine who has chosen to betray the service of the Emperor of Mankind and dedicate his soul to the service of Chaos and its foul deities.
