Description
The Ultramarines (13th Chapter) The Ultramarines Chapter originated as the XIII Space Marine Legion during the Emperor's Great Crusade in the 30th Millennium. Known for their strict discipline, tactical versatility, and Roman-inspired aesthetic, they are considered the "progenitor" for nearly two-thirds of all modern Space Marine Chapters. Their history is defined by their Primarch, Roboute Guilliman, their governance of the interstellar empire of Ultramar, and their role as the authors of the Codex Astartes
