Hi! My favourite legion are:
These guys are just awesome. I really like their fall from grace - a legion devoted to harsh, but fair justice against the enemies of mankind, that are turned into terror brining, sadistic criminals by an uncaring galaxy. Also, the skulls and colour schemes are great, as are the Altremar (?) and assault troops
This guy is brilliant, and the depth of his character is great ; living in the streets, hunting down the scum of Nostramo, but still dedicated to justice despite this... then a slow descent into madness as the morale of his legion detoriates. I love the his split personality, which is reflected in his actions in the Horus Heresy. Also, he is my favourite Primarch because, in the end, he was the only one who truly accepted his faults. I mean, who else what let themselves die when they realised what they had done? Certainly not the rebel primarchs after 10,000 years! Only he, out of all the primarchs, saw within himself the loathsome personality that had taken root, the very thing he had once fought to destroy. In the end, Konrad Curze was the best of them.
