The Novamarines is a Loyalist Space Marine Chapter and Second Founding Successor of the Ultramarines Legion. An ancient and proud Chapter, the Novamarines are hard-line adherents of the Codex Astartes who consider the writ of this sacred text, penned by their blessed Primarch Roboute Guilliman, to be divinely ordained law. In the past, they have been known to draw blood against those who would stray too far from the Codex.

"The existence of the Alien is a problem with but one solution: Extermination. When Mankind is alone in the cosmos, only then will we have achieved our destiny."
— Lucretius Corvo, first Chapter Master of the Novamarines
