This was what people thought of when they thought 'largest population' in the world; it was wall-to-wall people, vendors, and the like, that not even Ubon in his fox-form could navigate.  If you fired a gun in this crowd, you'd likely kill three people it was so packed, and that's just with the bullet.  Finding such a place would require her to look in some less-than-savory places though, and that would take time and effort...<br/><br/>(Charisma + Persuasion to represent searching the area to find what you're looking for... then roll an Intuition + Perception ^_^)
