Juliana has a habit of keeping her past to herself, unless directly questioned about it then there isn't much she won't share. She was raised by her grandmother until she was fifteen, then she struck out on her own and did some things, and then some other things, which led to another thing, then she disappeared for six years.
Currently, she's settled into the little cottage her grandmother left to her and makes her living collecting bounties for the Twin Adders.
