Maloghurst
From Lexicanum
Maloghurst was a Space Marine of the Sons of Horus Legion (previously known as Luna Wolves). Known as "the Twisted" for the complex workings of his mind, Maloghurst was Horus' chief advisor and public voice, and a shrewd manipulator. He was also a formidable warrior, and was a speculated contender for the First Captaincy (the post held by Ezekyle Abaddon) when Horus made him his equerry.
During the Battle of Sixty-Three-Nineteen, Maloghurst was dispatched to the surface to parley with the "Emperor of Mankind", the imposter leader of the planet, but his Stormbird was shot down and he was seriously wounded in the crash. He was recovered from the surface, and the remembrancer Euphrati Keeler's pict-records of the rescue spread through the 63rd Expedition, making Maloghurst into a war hero. His body was badly mangled by the events (thus truly making him "twisted"), but he remained willing - and quite able - to serve his Warmaster.
His role in the Heresy itself was as Horus' chief enforcer, ensuring that the Warmaster's orders were carried out. To this end, early on he employed the services of the mute assassin Maggard after he was freed from service to his overbearing remembrancer mistress Petronella Vivar. He also directed Calas Typhon of the Death Guard to stop the fleeing frigate Eisenstein before it could escape and warn the Emperor of Horus' treachery.
