From publisher blurb:
Ferret’s Den is a settlement in the forests west of Warrior’s Respite in Chandra’s Haven. Known by word of mouth only, there are no major roads leading into the settlement from either the Centaur Borderlands, or elsewhere in Chandra’s Haven. The way to Ferret’s Den is well disguised and guarded by bands of thieves loyal to one of the four Circles in the settlement. Adventurers interested in finding the elusive settlement must first pass a test at a neighboring Thieves’ Guild.
While there are more street brawls and open access to what might otherwise be underground trades in Ferret’s Den, the residents still take pride in their home. Belligerent behavior or flagrant disrespect is a good way to get expelled from the city (if not have a throat slit).
