Bharag's investigations start to bear fruit rapidly.
The first thing everyone hastens to assure him of is that there's no truth to the rumor that a zealot cleric of the Silver Flame is coming to Terminus station. He may have flung a skycab driver who tried to cheat him on a fair to his death on one of the pointiest buildings in Sharn, then destroyed the skycab in a ball of fire, from whence he was rescued by a spear carrying angel who shoots black fire from her hands, but the watch is carefully patrolling Terminus station. Heck, a patrol comes here and starts checking papers nearly every fifteen minutes!
There are two places available on the roof of the mail carriage, no problem. One gold each, bring your own rain gear.
Fortunately, Sharn is nearly tropical, so riding on the roof isn't cold. But it may be wet and it will be buggy.
Bharag's lie about a cousin dying in First tower shames one middle-aged gnome into giving up his inside seat ticket. Full of sympathy for Bharag, a stranger in a strange land, he hands him his business card and encourages you to call on him if you need any help managing legal matters.
A woman in a veil overhears you, looks at you oddly, and goes back to scanning the room as though looking for someone.
Bharag, make a Spot check
