Remember back in the Great Crusade, where the Emperor lead his new Astartes to the stars with a mighty battlefleet?...

Well, I was just wondering... If he lead them, he had to have some sort of Flagship right? So, what was it?

And, if you don't know, what do you think it looked like?
I mean, it had to have been one big a** ship... Larger than a Retribution Class probably? :yes:
