Honestly, I don't have a lot really fleshed out yet.
I was thinking that maybe both of her parents' deaths could have something to do with the anti-magic movement that is going on in Connlaoth. Maybe there's some sort of underground assassination group that is trying to kill out all the magic in the region-- even if the people aren't doing any harm?
That's just one idea-- but I'd really like to collaborate with whomever decides they want to help Atalia find out about her parents. I think it'd be cool. :)
