I didn't handle Weaving so I'm not too sure myself, but I don't think Weaving is a lost art if that's what your Bio is suggesting. I'm also questioning how she managed to survive multiple demon attacks, but than again I know that not all demons are as almighty as I portray them. But than again, I don't know what sort of demons attacked Meirin. I also want to know how exactly having Nightmares is going to impede Meirin. It's a curse, sure, but how would it affect her while she's awake?
