Sweet, I updated Accalon’s sheet to include this.
Also I talked to GFA, and she's game for are characters knowing each other before hand, so if this will help you go for it.
We'll need to expend upon this but this is the basics, Accalon has done strong arm work for her guild and that T'aria was her contact. She would have no real idea of his diseased nature but has been around him long enough to know of his unusually perversion for whores...
Obviously she could be in the house waiting for him while he inspected the wares.
Does that help any?
