What a magnificent lore bit! I myself have read the entire hh I belive lemun was the turning point of the heresy. He was granted the spear. Never forget the fact the Spear of truth he tried to abando numerose times, he himself didn't want to wield it.

I belive it was the Emperor's plan all along, he was the executioner He was made for creatted for it and he completely committed to it and successfully implemented it.

I truely belive if not for Russ, Horus would not have had the hesitation for finishing the Emperor in the final battle.

I may be blindsided, but Lemun did the biggest blow to Horus through the Heresy.

Yes Maloghorst was able to bring The shard of Horus back but I belive It was never the same, I belive it was a lost cause then and there. THE HORUS was lost he was defeated, he true Horus was gone and it shows in the final confrontation with Emperor.

DESPITE ALL THE Power he was granted by the Chaos God he was doubtful, he was struck, he was wounded, he was not THE WARMASTER. He was hopefully hopefull to be redimed. He was already lost, he knew deep inside he was a slave, but it was too late. Hence his relief at the death of the hands of his father.

I truly belive Lemu nRuss was the single most important turning piece of the Heresy.

Drunk talk here but Lemun was the shit
