Please change Vulnerable to Dark Secret or Powerful enemy that secret obviously being her connections to the Boromer guild and her enemy being her father.
Dark Secret
You have some sort of secret that, if revealed, would make you an outcast amongst your society and companions. While this secret is on your mind at all times, it will come up in game play only once in a while...but when it does, watch out!
Powerful Enemy
You have an enemy after your hide that is more powerful and influential than you are. They are not necessarily constantly after you, but it's always a threat that causes you to keep an eye over your shoulder. This may be taken more than once, but keep in mind that your life expectancy will become much shorter each time you take this flaw.
Whichever one will make the game more interesting is fine with me, tossing out future plot hooks and options DM

doncha love players who potentially screw themselves later for your amusement?
I can't see Nel being 'vulnerable' it was a quick flaw I chose when I had the UA and not the other list. thanks!
PS. that raises her AC by one to 18
