We March For Macragge!

The Ultramarines are considered one of the strongest and most honoured of all the Space Marine Chapters in the Imperium of Man, and were responsible for almost single-handedly holding the Imperium together after the Horus Heresy. Highly disciplined and courageous warriors, the Ultramarines have remained true to the teachings of their Primarch Roboute Guilliman for 10,000 years.

The name "Ultramarines" is a nod to both their standing among the other Space Marine Chapters, and their role as the source for more Chapters of Astartes than any of the other former First Founding Legions. The culture of the Ultramarines is loosely themed upon the culture of Old Earth's ancient Roman Empire, as exemplified in their Astartes' pseudo-Latin names and their strict adherence to the Codex Astartes, as well as the society of their homeworld and the Chapter's method of recruitment.
