The Dark Angels used several Volkite Weapons and ancient Graviton Weapons in their battle against the Emperor's Children, inflicting heavy casualties.
The Emperor's Children unleashed an ancient Helbrute. Chaos Dreadnoughts did not necessarily house the oldest warriors; sometimes they imprisoned the most deranged lunatics.
This one was even more special: a supreme pervert who had entered his Helbrute voluntarily.
Fu Luha was a pervert among perverts. After committing every conceivable evil and being affected far too deeply by Slaanesh's blessings, he discovered, to his despair, that no indulgence could make him feel anything anymore.
(To be precise, the quantities required to feel anything were too enormous. For example, he had to eat tens of thousands of tonnes of food in one sitting to feel the satisfaction of being full.)
Then a few fellows looking for entertainment egged him on to enter a Dreadnought. Everyone knew that entering a Helbrute meant torment worse than death, but none of them dared try it.
Fu Luha happily accepted and did something utterly insane. The Emperor's Children Legion still retained its tradition of holding impromptu duels, and he entered an arena to challenge its reigning champion-a Helbrute that had dominated it for years.
He suffered grievous injuries, but killed the Dreadnought outright. His exquisite swordsmanship, perfect and elegant, earned him plenty of flirtatious looks from the Emperor's Children.
Fu Luha adamantly demanded that the Admirer who came to treat him stop the operation and entomb him inside the Helbrute he had slain. This turned his Admirer into an obsessive stalker, crazily infatuated with him.
I don't know why he demanded that, but it was seriously cool.
Now this strange Helbrute rampaged across the battlefield with astonishing sanity and mysterious pleasure. His followers were fighting with longswords against the Dark Angels charging up beside him
