If you use the Map Editor to change the Ident of one of the Fawn Guards to 2 and then talk to him, you get a different conversation. It seems to indicate that a female Avatar would be hounded around town to prevent her from hurting herself. The code is incomplete, so the guard will just stand there after speaking, and will use different guard titles for himself.
By Law, all Beauty must be protected. Therefore, I am to ensure that thou dost not endanger thyself.
Thou shouldst not provoke arguments, or stray too close to the docks where thou couldst be injured. I must intervene in any situation in which thy Beauty might be marred. That is my duty.
