AWeirdDude

''"So, I'm fighting my 'brother'? I'll be sure that my chainsword is shoved so far up his ass he'll be coughing up chainsword teeth!" '' -'AWeirdDude', upon being told to attack a wandering Iron Warrior.

A strange man, young yet in the equipment of Great Crusade-era Iron Warriors. He claims to have been lost in the warp, a soldier of a secondary reality, and was sent to the primary reality. While it sounds ridiculous, the warp has no essence of time and it's often been noted that AWeirdDude seems 'out of place' and strange. All old Iron Warrior markings have either been ripped off by his own hand or scratched away at with many blades.

Name: Unknown. Speculated to be Opteius, but is denied upon questioning.

Nickname: AWeirdDude.

Speciality: Siege warfare/planning. Also a decent techmarine.

Title(s): Self-proclaimed siegemaster (not out of ego, but more so his talents in the field), former Legiones Astartes captain of the Iron Warriors, Lawbreaker, Foulmouth.

Motto: "DEATH TO MY OLD BROTHERS AND DEATH TO CHAOS." Occasionally also filled with profanity.

Flaws: Hot-headed and has quite the potty mouth.

Entry to the main reality
"Out of place? HOW DARE YOU! I AM A GOD-DAMNED SPACE MARINE!" -AWeirdDude, upon being told by a guardsman he seemed off and out of place.

The origins of AWeirdDude are a mystery to even the best amongst the psykers, inquisition and other forces of the Imperium. He claims that throughout the Great Crusade, he was captain of the group of Iron Warrior Legiones Astartes who were aboard a Sword Frigate, accompanied by two other ships with their respected squads. He claimed that 'a large blast sent one other frigate into the bowels of space, and another was shot from orbit and landed on a dead world'. After which, he was lost within the warp - his ship blasted within the twisted confines of it, as he fell gripping to one of the final pieces. All he speaks of afterwards is shifting through the warp, until he landed on O'magudnis prior to discovery and using a stasis field to preserve him for as long as possible, knowing that he'd be discovered at some point, whether it being into open arms or awaking with a bolter between his eyes. 10 milliena later, in M41, the M31 technology finally broke down and he was forced from his suspended state. No clue where he is, what has happened or what time he's in, he wandered alone into the wilds.

Learning of the M41 situation
"Let me get this straight. My brothers have rebelled against the Imperium, even with their unwavering faith of M31?"

"Yes... But what makes you bring up M31, br--"

"FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU"

-Transcript of a discussion with a Cardinal Archivist brother, not long after joining.

M31 is much different from M41. AWeirdDude had to learn this the hard way, finding the Cardinal Archivists on their homeland - he saw visions of the Iron Warriors relentlessly assaulting them during his time in the warp, almost like a vision of sorts. Now wandering the lands of O'magudnis, he had noticed the presence of the other marines, and didn't want to take his chances. M31 era knife in hand, he took to attempting to dislodge the icons and badges... If it wasn't bent the moment he pushed. So what did he do? He ripped them off with his BARE HANDS.

Eventually, with worn armor and no supplies, he had no chance but to either succumb or hand himself over to the Cardinal Archivists. He chose the latter, proving himself to them and finally being recruited, primarily for his talents. All the ripped marks and scratched trinkets were replaced by markings of the archivists, and he used his Iron Warrior talents to his advantage, being a pivotal warrior in the work of the archivists.

Equipment
Most of AWeirdDude's equipment is M31 pattern weaponry and armor, heavily modified to be on par with the modern equipment. He outright refuses to discard his M31 equipment.
