As all should know there are eighteen Primarchs nine loyalists and nine traitors but there are also two unknowns the second and eleventh Primarchs this is a story focusing on the second Primarch named by his father simply Alexander now this father unlike the fathers or rather adoptive fathers of the other Primarchs was the Emperor for when Chaos stole them one was saved by the Emperor the second Primarch. He was different from the other Primarchs in a multitude of ways for one he wasn't sterile he was also comparatively short when you looked at his brothers he also happened to experience puberty due to the fact that he was so different. There was also one other thing that set him apart from his brothers which was the fact that he had the ability to project an aura just like a null. This is the story of what happened to him.
-Room underneath what will be the imperial palace-
"Alexander, are you ready?" the Emperor asks his son
"Yes father, I am ready for us to begin" Alexander responds walking over to the control panel to the portal he and his father had been working on.
Alexander was at this time wearing his custom-made power armor that was in the form of samurai armor that varied in how the helmet looked and was carrying a custom made master crafted bolter named Nagusame and a master crafted power sword shaped like a Japanese odachi named Kurushimi. He then put his helmet on and began pulling down on the lever in front of him while his father did the same. Suddenly a blue portal of eldritch energy formed in-between the two pillars. He then began walking towards it.
"So it did work" He said in the raspy voice caused by his mask.
"Indeed it did" His father responded suddenly it shifted to red and an arm of red energy shot out grabbing at the Emperor only to be intercepted by Alexander throwing himself in front of it.
"Ahhh!" he screamed as the energy burned him ignoring his armor it then pulled him into the portal right as he activated his null aura to try and stop the portal. Right after being pulled through he lost consciousness
-Emerald Forest During Initiation-
"Ahhh!" Alexander yelled as he fell through the forest and onto the forest floor having sprouted a massive headache and so quickly roping in his null aura hoping to decrease the strain on his mind to little success. He then decided to get a grip on his surroundings the first thing he noticed were trees and greenery which he had only seen in holo-vids when learning about what terra used to look like. He then decided to try and find civilization by choosing a direction and walking in it. He soon saw a giant shadow pass overhead and looked up just in time to see a girl dressed in a red cape jump off of it. he made a quick decision to go help the girl and started running in the direction she had fallen.
-At the Forest Temple-
"Yang your sister" Blake yells at Yang
"Yeah, I se... What is that!" Yang yells pointing to Alexander who had just come running out of the forest.
"Yang what are you... Holy Shit!" Blake yells looking at where Yang was pointing. Suddenly he jumped up to catch Ruby before she could hit the ground he caught her and then ducked into a roll coming to a stop in front of a speechless Yang and Blake before letting Ruby down.
"Are you okay?" He asked Ruby unknowingly terrifying them with his raspy voice.
"Y- yes" Ruby responds scared right as she says that the stranger turns to see a boy crash into a tree and another girl this one dressed in white fall from the bird. Who he again runs over to jump up and catch. He catches her and sets her down on her feet.
-On the Cliff with Ozpin and Glynda-
"Ozpin we need to interrupt the initiation and get those girls out of their it could be dangerous" Glynda says pulling out her riding crop.
"Glynda, It just saved two of the Students it's no dangerous" Ozpin said while sipping his coffee.
-Emerald Forest Temple with Everybody There-
"Oh great, now we can all die together" Yang said sarcastically suddenly the giant thing which yang was thinking was one of Atlas's robots drew a massive 6 1/2 foot sword and started walking toward the Death Stalker.
"Stand back" It said Before pulling a sheath off the blade and it ignited in a strange red eldritch blade and the right side of its face began burning with the same flame. The strangest thing was that as it got closer the Death Stalker started to become nervous and started crawling backward as it saw the flames until the being suddenly shot forward and stabbed his blade through the Death Stalker causing it to make sounds of pure agony where the blade touched. It then spun around and pulled up a giant gun and shot three times at the Nevermore which had circled back around. The first shot blew its right wing off the second hit its chest and the third blew its head off. It then calmly swiped its sword getting all the grimm ichor off and sheathed it before sticking its gun onto a mag plate on its thigh.
"Done" was all it said before a bullhead came down and Glynda pinned him down with her semblance.
-On the Cliff While Alexander was fighting-
"This is unheard of" Glynda shouted pacing back and forth "In all of history no grimm has been scared of man's creations"
"Well, we have also never heard of a 9-foot tall creature before" Ozpin replied before grabbing his scroll and calling a bullhead to bring them down.
-In the same room underneath the imperial palace-
The Emperor is talking to a sister of silence telling her about what happened and how he might be able to send three people there.
