Operative Delgado,

I just wanted it to be known that an elven killer bearing a godstone set upon me in my room at the Rock Bottom this eve. The Watch was unsuccessful in preventing him from making an easy escape. The directness of the attack coupled with his posession of the stone makes me presume that it was Zau. That and he said I had been looking for him.

Just for your information, Luminary Mylin
