Standing here is Perturabo, Lord of Iron.
The Imperium of Man's fourth Warmaster, supreme ruler of the Four Hundred Worlds of Olympus, Lord of Iron, Augustus, Emperor... These are just some of the titles mortals use to honor him.
He came to this universe by accident and fused with the soul of the Fourth Primarch. Even he does not know which of them is truly the dominant self.
Perturabo had never intended to meddle in other people's affairs. He only wanted to live his own life. But when that day came, he looked around at his sons, his subordinates, and the hopeful eyes of his brothers, and in the end, he agreed.
Everyone,
Muster the troops, assemble the fleet. Our destination is Terra. We march to save the Emperor!
Did you see the ticket? Don't update soon.
At present, it seems that the historical flavor is not that strong.
Personally, I think it's okay
