“In the process of the Primarchs’ creation, the God-Emperor often cited an ancient recording dating back to early M3, which has since been destroyed. We can only speculate on the artifact’s contents, and what warranted its total erasure from Imperial history.” - Unknown
I think the perfume bit was more a reference to death guard using chemical warfare and having a legion wide license for the forbidden chemical weaponry also I'm almost sure Alpharius and Omegon would be a duo of pathological liars
This is what Malcador wanted btw, he tried to convince the Emperor to make the Primarchs women since The Sigilite thought it would make them less glory hungry and more pragmatic
Mad respect for the black hair take. Also the autism thing was genuinely appreciated, i know exactly what you mean. Anyways here's my ranking in order of legion.
Lion - C tier, probably would think she hates me because she keeps so many secrets and keeps me at a distance.
2nd/11th Legion - Probably already female space marines in the normal timeline idk
Fulgrim - B tier, probably would rock your world but also I'd feel inadequate, more so than usual. However, she'd probably encourage the persuit of perfecting yourself so that'd be great.
Perturabo - C tier, her pointing out all of my issues would stress me out and make me feel like she hates me, however she's probably just as likely to work on a fun project with me and show me how to improve at any of my crafts.
Khan - A tier, life would be a constant thrill ride and I'd be alright with that.
Russ - B tier, probably one of the most fun Primarchs to go do stuff with. Probably would try her drink on accident and implode.
Dorn - D tier, I feel like it'd be a very unhappy relationship with the bottling.
Curze - S tier I can't fix her, she can drag me into her downward spiral though. Roller coaster of emotions, flaying of people, general disregard for humanity, hatred of most people, and probably horrible hygiene aside, it'd be great!
Sanguinus - A tier, ideally I'm dying before she does. Worth the tears, also the legion would probably support you in your mourning if you live through that.
Ferrus Manus - B tier, probably very chill to tinker on stuff with and learn from. The Iron Hands are fine.
Angron - F tier I don't want nails in my skull, Khorne is the lamest Chaos God, the endless shouting would give me a headache.
Guiliman - A tier, she'd have the perfect schedule to fit everything she can into the day. The house would be immaculate. However I'd Probably have to catalogue all purchases in Excel and learn how to manually do imperium taxes to take a load off her shoulders.
Mortarion - D tier, not for personality or design, but because standing in the same room would probably kill me or turn me into a plaguebearer.
Magnus - B tier. Probably a lot of fun to be around, probably also a bit overbearing and likely rants about her sisters screwing her over constantly.
John Heresy - B tier, Chaos Girlboss the that almost killed the Femperor. Unfortunately a little too lost in the chaos sauce.
Lorgar - A tier, probably genuinely faithful and would love you like no other, outside of her God. Also 100% a freak, gets a little too into it after a crisis of faith, but it's honestly kinda hot.
Vulkan - S tier, learning her craft alongside her would kick ass, and she's probably a beloved community member wherever she goes. Just chill in every single way.
Corax - #1 top of S tier, I am not immune to the emo aesthetic, but also personality wise she's the best. She's quiet, caring for those around her, does her best to make the world a better place, also introverted, would be chill to go nonverbal with and relax, sets realistic goals, and generally is the ideal partner.
Alpharius/Omegon - C tier, I feel like I would go insane in a very literal sense by being with them.
