Fluff and plot points

>Dorn and Pert discussing combat scenarios near their legion
>Eventually devolves into a debate about their abilities
>"It's not like you could ever do anything against my massive artilerry"
>"Sister, you'll find that my thrusts always bring pleasurable results"
>"Not without you attacking through my rear, which I'd never let happen"
>"Who knows, my Legion is famed for their stamina and determination, they would be able to push through regardless"
>"Well, maybe i'd let you through a bit, only to get you into a trap, with me then remaining on the top"
>Entire legions are chucling and commenting to themselves
>Primarchs have no idea why, they think they are really only talking tactics no matter how different they feel when "debating" with one another
>Sigsmund meanwhile has managed to stab his sword through a wall
>With the power field turned off


>Dorn would end up thinking siggy hates pert due to an outburst of “fuck her, fuck her, just fucking fuck her you stupid fuck!”
>And so the seeds for the black Templars are planted


>If we are going reverse iron cage, maybe the reason why the Imperial Fists survive, instead of ultrasmurf meddling, when Persephone, witnessing Dorn and his last sons, battered and broken, surrounded by piles of the dead, realizes that she doesn't actually have the will to actually kill her brother, who she was to autistic to realize she actually had feelings for, until it was too late. So, when fists don't even have ammo anymore, she orders her men to stand down and cease fire, allowing Dorn and the last Fists to escape, much to Sigsmund's fury and Dorn's confusion
