Damage? I assume you mean physical damage – mental is beyond me to calculate. I have Nasriel's permission to tell you all this, by the way. So. In order, least to most worrying. Two months at Chu'unthor have dealt with some of it by sheer time, but I'm afraid it does mean most of the scarring is permanent.
These holos are on her file now, locked of course. Yes, poor Nasriel indeed. The lines are from a beating with an electrical wire. No, not live; these are electrical burn scars. For those it was just a wire used as a whip. That? Thermal burn, probably a cigarette or herbal. This holo... hmm. Ah – pieces of soft tissue removed. With pliers, by the look of it. Grip and twist – see the star shape? Would have hurt like hell.
What next? The bastards broke her arm and it knitted crooked, so I've had to break it again to reset the bone. Bacta, and it'll be useable in a day or two. A vast array of bacterial and viral infections – all the usual suspects, and a few more besides. Don't look at me like that, you knew where she was. Be grateful she's still negative for the autoimmune viruses, because even I can't fix those. Antibiotics for the rest.
Dreadfully underweight, but you knew that. She's not even to enter the dojo, much less duel, until she's back past... I'll make it thirty-five kilograms, which is still far too low, but survivable. Understood?
The blood loss is immense, and it troubles me, not least because there is not a single person in the Temple who could serve as a blood donor. No, don't even suggest it – she's Brycherin-neutral, which is rarer than I care to think about, and blood with the X or Y factors would kill her outright. She'll just have to take it easy for a while.
Is that all? Let me check my notes. Two teeth knocked out. Mild case of consumption – antibiotics for that as well.
I know I'm not qualified to discuss mental damage, but... be nice to the girl, unnatural though you'll certainly find that. Let her take her own time over talking about what's happened. And if you so much as insinuate in her hearing that any of this might have been her fault, so help me I will kill you myself. Don't expect everything to jump back to normal, either. Because it won't. You're all she's got right now. Make it count for something.
