Tyranny of Dragons
The Zhentarim seeks to become omnipresent and inescapable, more wealthy and powerful, and most importantly, untouchable. The organization offers the best mercenaries money can buy. When a merchant needs an escort for his caravan, when a noble needs bodyguards to protect her holdings, or when a city needs trained soldiers to defend its honor, the Zhentarim provides the best-trained fighting men and women money can buy. However, the cost of doing business with the Black Network can be high.
Rumor has it that the Zhentarim are involved in extortion rackets, smuggling, and other illicit services and its members have often been accused of suborning local officials. Those who’ve dealt with the Zhentarim and managed to walk away intact say the Black Network’s ultimate goal is to make everyone dependent on it.
