After the Fall
You call your home the bazaars and trade tables of The Great Worm and dealing in both goods and information is in your blood.
Gain a +2 Origin bonus to either Appraise or Knowledge (Local), and gain either Cosmopolitan or Deceitful as bonus feat.
Dealings with devils is frowned upon everywhere except in the Great Worm (or in strictly Evil places), and the stink of the Worm’s diabolical overseers follows you wherever you travel, making people wary. You incur a -4 penalty to all Bluff and Diplomacy checks when dealing with anyone of a Good alignment (provided they too frown upon devils).
