The '''{{PAGENAME}}Armour Indomitus''' is a [[Space Marine]] relic. This ancient suit of [[Artificer Armour]] was forged long before the [[Horus Heresy]], and many [[Masters of the Forge]] have made pilgrimages in order to study it first hand. Most of these Masters maintain that it is the blueprint for each model of Space Marine [[Power Armour]], and that its inbuilt [[Machine Spirit]] is so complex that it must be blessed every morning and evening to ensure the suit will maintain peak performance. Unlike [[Plasteel]] and [[Ceramite]] Power Armour, the Armour Indomitus is made from layered plates of raw adamantium, making it very heavy but all but nearly impenetrable by conventional weaponry. In the face of even heavier fire, it incorporates a [[Force Field]], the secrets of which have long since been lost to the [[Imperium]].{{Fn|1}}
