The Zhentarim
Members of the shadowy Black Network consider themselves part of an extended family, and rely on the larger organization for resources and security. The Zhentarim recognizes and rewards ambition, granting its members autonomy to pursue their own interests and gain some measure of personal power or influence. In this way, the organization is a meritocracy. The Zhentarim welcomes dangerous times as opportunities. When a merchant caravan needs an escort, a noble needs bodyguards, or a city needs trained soldiers, the Zhentarim provides the best-trained fighting forces money can buy.
Zhentarim agents traveling to and from Mantol-Derith have recently passed on information and rumors concerning demonic activity in the Underdark. Even the most cautious member of the Zhentarim knows that demons at large in the world are bad for business. The organization thus views the possible presence of the demon lords in the Underdark with the same concern as any other external threat to their way of life.
