Primarch Mortarion

With heavy foot falls the primarch walks, staring at each son as he pass's, all eyes upon him from his small to his veterans. Even those entombed within corrupted iron vessels of steel.
He speaks, muffled and sad," My sons, we fight not in only hate, but in sorrow, for my father does not understand how we sacrificed so much in his name to eliminate the blight of the imperium. Thus we walk now again to spread it, for he has forsaken us, and thus we march to spread the word of father nurgle, who understands who we are." and with a wave of his hand the tides of the death guard walk forth once more at his behest.
