I watched this over the 2 years it was made. Watching Richard's live streams as he showed how he did it an made the choices he did. In this, Richard make's directorial decisions and focuses exclusively on the story of Grimaldus, Recclesiarch of the Black Templars.
The Black Templars are the most religiously zealous of all the Adeptus Astartes (Genetically engineered TransHumans) and a Recclesiarch is supposed to be the most zealous of them all. He is the Spiritual leader of the Chaplains of his chapter, who are the spiritual leaders of their battle brothers. Adeptus Astartes, or Space Marines in colloquial terms, are warrior monks, determined to the protection and advancement of the realms of Humanity called the Imperium of Man. They worship, along with the 1 million (plus) worlds of humanity, the Emperor. The Emperor was the supreme pinnacle of Human evolution, and was the Omega Plus psyker that guided humanity through 50000 years of evolution. He now resides as a living corpse on the Golden throne in the Ancient home world of Terra, his guiding mind still taking an active role in the lives of his Imperium.
Grimaldus and his Squad are dispatched to the Hive City of Helsreach, with orders from the High Marshall to defend it to the death. Grimaldus knows it's a death sentence for him and his men but he goes, taking his men into the very hell that he knows where he will be left dead, bereft of Glory and honor. Journey with Grimaldus as he re-encounters his basic humanity that reignites his fires of faith to a massive climatic battle against a numberless horde of enemies. But is that enough to carry him through the battle or will he end up on the endless cemetery fires.
