Editing E6 3.5 The Motley Crew (section)

==The Karstfells==
The Fells have a bad reputation, getting steadily worse the further west you go...which pushes Bladhames trade route undergound, where these attacks, oddly, never occur.

Your character might have been driven out of the Karstfells as a child...or know more than he's telling.

Considering the Karstfells as the fantasy equivalent of Bolivia/Central America cave system wise, this creates an environment where the surface is bleak and dangerous and the underearth is possibly safer and a more diverse, vibrant ecology...probably connecting to underwater rivers and ocean openings [a sunless sea or two?], where ancient marine races have found their contemptuous
conquerers to now be a thing of history...
