How about the winner get a kiss from the loser? Do you wanna end up in a coma? You can drain my energy any time, chère. Gambit has plenty.

“I should have told you, [my heart] it’s yours”

Aerix's oldest memories are of fire. Her homeworld was infested with orks, but the foul xenos were forever kept at bay with massive walls of fire. In times long past, ancient human colonists had also torn open large parts of the world's thin crust to expose massive oceans of liquid rock, which burned day and night. The perfect cauldrons for heavy industry and manufacturing.

Fire was safety. Fire was control. Fire was survival.

The moment her psyker powers awakened, Aerix lit a man's head aflame when he threatened to cut her father's shifts at the manufactorum. Without the fire of industry, her family would starve, so she used the fire inside of her to save them from the arrogant and cruel foreman.

On the black ship bound for Holy Terra, Aerix dreamed of fire. And during the years she spent undergoing the soul-crushing process of becoming a sanctified psyker of the Imperium, her thoughts of fire, of the Emperor's ever-burning light in the warp, kept her... somwhat sane. Even as machines were drilled into her brain to keep the worst of her impulses at bay, she relished the flames that cauterized the wounds.

For years, she served the Imperium faithfully. In battle after battle, on countless worlds, she used her abilities and devotion to flame to serve her fellow man. Only a few people took notice that every single squad she was assigned to was inevitably found dead of horrific burns. Even on ice worlds where flame was near impossible to ignite, or jungle worlds drenched in constant rainfall. But her abilities were critically needed across multiple battlefields, so these unfortunate casualties were never followed up on.

No one ever thought to talk to Aerix. Too many people keep their distance from psykers, treat them like corrupted tools meant to die in terrible ways to repent for the crime of existing. So no one ever took heed of the fire constantly burning behind her eyes.

Aerix's summons to Theodora von Valancius' flagship, and the subsequent mutiny that opened her eyes to powers that had previously just whispered in the back of her mind, have snapped something in Aerix.

She has power now. And control.

Aerix von Valancius

Thank you so much for the tag, @harrenhalyuri!

I haven't developed Aerix as much as Nasosi, but the picture in my head is pretty clear. (fun fact, she's also my very first rogue trader OC, but the original aerix was quite different)
