Q6. Who is the richest person in the land?

You mean rich like in family and experiences?

In the area around Fortune, it would be Lord Corben, the erstwhile Castellon who escaped the predations of the rebellion.

In the Free City Region, Orbo Smallfoot, the head of the Acquisitioner's Consortium in Valor. Orbo was a former halfling street thief who started the Consortium as a way to lift his fellow halfling thieves out of the gutters and into a respectable life. A confluence of lucky breaks led to the Consortium becoming a favorite agent of the Valor nobility. The Consortium utilizes legal means whenever possible and maintains the strictest confidentiality of its clients and their requests. Prior to the rebellion, there was always the fear among the nobility that the AC might turn to blackmail. In the immediate aftermath of the rebellion, Orbo saw his wealthy clientele beheaded in the streets. Not great for business. But, as he had always sought legal means and developed the reputation for keeping his mouth shut, the nouveau riche among the merchant class came to see working with Orbo and the AC as a status symbol and business boomed. No one knows quite how much wealth Orbo and the AC have accumulated but it dwarfs the most generous estimates. Orbo is running Valor beneath everyone's nose.

Special mention must be made of the Black Duke. During the Dragon Wars, the Duke slayed the great gold wyrm Geldrynonth and trapped its soul within his blade. Now, the Duke can summon Geldrynonth by plunging his sword into a pile of gold, gems, and other valuables; the dragon's spirit animates them into the form of its old body, though still clearly made of treasure, with the sword itself serving as a claw or tooth. The size and strength of this new body is proportional to the amount of treasure used. And hidden somewhere within the impenetrable walls of Castle Malbork lies the entirety of Geldrynonth's hoard, or so they say.
