Since the fall of the city, the Cholden Thieves' Guild has been working hard to spirit their fellow citizens off the streets and into the relative safety of the sewers (in return for all their worldly possessions, of course).

This effort has been greatly helped by the Guild's encyclopedic knowledge of the city. To this end, the Guild leadership has created an annotated city map to provide to members (or sell to foolhardy adventurers) which outlines the dangers - and opportunities - that the fall of Cholden has created.
