19th Founding

The 19th Founding

The 19^th Founding of Space Marine Chapters occurred during the mid-36^th Millennium. There are only two known Chapters that were Founded at this time -- the Avenging Sons and the Steel Confessors. The Avenging Sons were created from the gene-seed of the Ultramarines. This Chapter proudly maintains vaunted martial traditions and their stoic faith in the tenets of the Codex Astartes written by their Primarch Roboute Guilliman.

The Steel Confessors Chapter was secretly Founded by the Adeptus Mechanicus for its own use, using Iron Hands’ gene-seed that had been collected from that Chapter's tithes to Mars. The Adeptus Mechanicus took it upon themselves to create a Chapter that only bore loyalty to Mars and the Cult Mechanicus in an effort to better protect their Forge Worlds and private interests. Unfortunately for the Adeptus Mechanicus, the Inquisition discovered their machinations and reported the act to the High Lords of Terra. After much deliberation, the High Lords decreed that despite the Adeptus Mechanicus having greatly over-stepped their mandate, they would be allowed to keep their newly-created Chapter, within certain limitations. The Steel Confessors were required to take the same vows of fealty and loyalty to the Imperium of Man that bound all other Space Marine Chapters and to separate itself organisationally from the Adeptus Mechanicus so that it operated as a truly independent Chapter.

After their discovery by the Inquisition, the Steel Confessors were forced to become an independent Chapter of the Adeptus Mechanicus, but they still maintain unusually close ties with the Mechanicum of Mars. They recently successfully defended their homeworld, the Forge World of Kalevala, from an attack by the Tyranid Hive Fleet Leviathan, though at great cost to the Chapter.
