Maybe he's got some real life stuff going on. :/

In the meantime, I'll just go over your sheets.

Elizabeth: I'm not sure where the obscure number of magic/runes came from but I had hoped I had implied by saying 'elemental' magic, that the basic elements would only apply: fire, water, air, ground, and darkness. So she can know all 4+darkness but I would reckon it's rare to be able to use all five for one person so if she knows 3-4, that would be fine in my book.

I'm also curious about the other siblings. Is it just her and Carmella? Or do they have brothers? You indicated Elizabeth to be the eldest daughter but is there an older brother who handled the wartime while Carmella did not (in the beginning)? 

Other than those two issues that need tweaking, the rest looks fine to me.

Carmella: I'm never too fond of 'sickly' characters personally but I do like that she seemed to take an interest in medicine, despite (or perhaps due to?) her own ailments. I don't really any corrections to say for her, everything looks good. She seems to have a good foundation but clearly needs to find her own voice and strength outside of her sister's shadow which I look forward to seeing unfold.

I will say on both sheets, I wouldn't mind a little more context in terms how old they both were when some of their events occurred but if you want to remain vague, that's fine.
