Bat girls

A while back I had a dream about a few Illyrian females running away and starting their own warband in the woods, being all badass and stuff. I decided I didn't want to wait until SJM had published silver flames to see if there was such a thing, and just write a fanfic.
English is not my first language. Aside from a smutty fanfic I have never written fanfic before. Im 100% open to feedback and tips, but please be nice.
