Alpharius the Stranger

"If you do not believe I am the Primarch, then why even ask?"

- Alpharius Brilliant, resourceful and ruthless as one would expect an Astartes of the infamous Alpha Legion, 'Alpharius' is a mysterious Chaos Marine insurgent who has perpetrated many acts of terrorism against the Imperium of Man. While, like many marines of his legion, 'Alpharius' takes the name of his Primarch, he has earned enough enmity from the Inquisition to earn the epithet 'The Stranger.' Indeed, Alpharius the Stranger has a tendency to hunt Inquisitors, slowly wearing them down with sadistic mind-games before cornering them, leaving their remains as a warning to their peers. Showing very few visible mutations, Alpharius is good at impersonating Loyalists when necessary, and is usually served by a highly trained team of Renegades he has personally corrupted.

History
"You know who I am. I told you when you asked me. I am Alpharius."

- Alpharius the Stranger There is no way to ascertain Alpharius' past, even if he were the kind of man to speak about it. When asked, Alpharius simply gives the same answer common to his legion, that they are Alpharius. The Chaos Marine's resourcefulness, experience and brutally pragmatic fighting style speak of centuries of experience, but some Inquisitors argue that this specific Alpharius could easily be a convenient alias for Alpha Legion agents operating in the area, further complicating the issue of the Astartes' identity.

Needless to say, the first sighting of this Alpharius was in Subsector Aurelia, where he orchestrated a several uprisings to distract the Blood Ravens who protected the area, and succeeded in assassinating an apothecary and stealing several samples of Gene Seed. Whether or not he was acting as a scout for the Chaos invasion that would later attempt to claim the capital planet is unknown. This specific Alpharius is known for operating with a squad of personally corrupted renegade Space Marines, and connecting several seemingly unrelated incidents that caused scenes of carnage and rebellion across widely disparate worlds made the Inquisition realize exactly how much of a threat this Astartes was.

As if understanding that the Inquisition targeted him specifically, Alpharius and his team seemed to target Inquisitors specifically, slowly stalking them, breaking their spirits by killing their retinues and foiling their plans. Only when they are utterly broken, does Alpharius and his team close in for the kill. Over the centuries, Alpharius has murdered no less than nine powerful Inquisitors, and many more lessers that decided to aim above their ability. Several rare pictures of the Astartes shows that he keeps trinkets of his victims on his power-armor. Alpharius is remarkably reasonable and affable for a Chaos Space Marine, and can often pass for a Loyalist to people who do not know better. He makes extensive use of cultists, usually highly trained and extremely loyal to their masters, who appear to treat them as valued warriors. Among agents of the Inquisition, Alpharius is infamous for his ability to make Loyalist marines betray the Imperium. Despite all of this however, Alpharius is utterly merciless towards anyone that goes against his mission, and he is certainly not afraid to use the Ruinous Powers against his enemies, having earned at least one mutation, a pair of prehensile wings that can be retracted at will.
