Stryken Primus is a vital Forge World of the Adeptus Mechanicus as well as a Knight World located in the Segmentum Obscurus. Located near the Warp rift known as the Eye of Terror, this Forge World is responsible for the production of munitions for the Imperium's fighting forces standing sentinel over the Cadian Gate. Interestingly, Stryken Primus has no Titan Legion of its own, and is instead guarded by several Knight Houses that make up a standing guard of Imperial Knights known as the "Order of Iron."

As with many Forge Worlds, the early history of Stryken Primus and its surrounding star system has been lost over millennia. Situated far in the galactic northwest, the Stryken System's principal planet is the smoke-wreathed Forge World of Stryken Primus. The system's industrial heart is protected by a ring of three Knight Worlds in close proximity -- Stryken II, IV and V -- and each is home to several knightly houses.

These verdant planets were once Maiden Worlds of the Aeldari. The ancient tribes of Exodites and the many different species of giant reptiles and bipedal carnivores once present in the system were ruthlessly driven from these worlds by the knightly houses that were established shortly after Mankind's arrival in the system in the distant past.

With the combined might of no less than eleven Knight Houses to call upon, including such luminaries as Houses Arokon and Dorath, the Forge World of Stryken Primus has no Titan Legion stationed upon its surface. The planet instead focuses on supplying munitions in enormous quantities for the Imperial forces defending the Cadian Gate. A standing guard of Knights -- the Order of Iron -- is always present on the surface of the Forge World to ensure its protection.

House Dorath's valiant Knights have ever dominated the ranks of the mighty Order of Iron -- the elite guardians of Stryken Primus. Drawn from amongst the greatest and most capable Nobles from each House, competition to be accepted into the Order of Iron is fierce, and it is considered a great honour to join the Order's ranks. The head of the Order is given the honorific title of Forge Warden, and leads the Knights in battle as if he were a ruler of his own knightly house.
