The Black Templars Armor is a power armor set in Space Marine multiplayer. It is a DLC item that was first available to players who pre-ordered Space Marine from GameStop or Amazon.de (First Edition), and later released as part of the Emperor's Elite Armor Pack.
When the Ultramarines Primarch Roboute Gulliman called for the remaining Space Marine Legions to be broken into smaller Chapters after the Horus Heresy, the Imperial Fists Primarch Rogal Dorn refused to have his Legion split up. After a tense stand off Dorn agreed, and the Imperial Fists were divided creating the Crimson Fists and the Black Templars. Upon their creation the Black Templars swore to take a never ending crusade against the enemies of humanity. Eschewing the idea of a home world, the Black Templars have instead, taken to the stars in mighty crusade fleets, actively seeking out the enemy throughout the galaxy.
