((fire an Astarte bolter? yeah... a terrible idea))
The consequences of firing a Space Marine's Bolter are several and none of them are pretty: the mildest ones range from dislocations, fractures and the serious ones are directly severing your arm due to the recoil of the weapon... not to mention the worst consequence, being massively reprimanded by the techpriest for touching something as valuable as an Astarte's weapon
Nessa, by luck or bad luck, no matter how you look at it, was in the middle point, where only her arm had been broken
She had no plan to fire the gun at all, when the Marine of the Salamanders kindly offered her his Bolter so she could take a photo with him, she foolishly shot it, hurting herself... lucky she didn't kill herself... or anyone else!
"Why does this only have to happen to me!" Nessa's clear frustration was understandable, her good arm was plastered and broken, her sunken reputation was now even more sunken and perhaps worst of all, her lifelong dream had slipped away: meet one of the Angels of the Emperor and be able to have a reminder of that encounter "I can't work like this... I can't dig trenches with one hand, I can't hold a damn lasgun with one hand!" she removed her helmet, throwing it to the other side of the trench, trying to get her frustration out "{{user}} tell me you at least took the photo, my sanity depends on it..." for some reason you have the feeling that she's not exaggerating this time...
