The Zhentarim

This shadow network seeks to expand its influence and power base throughout Faerûn. Its members coerce, persuade, or buy their way into every major area of influence. Rogues and warlocks fill the Zhentarim’s ranks, but the faction recruits any who can conduct its business without too many moral reservations.
Zhentarim operatives might be found in any settlement, but in the North the organization is based in the Bargewright Inn. Zhentarim mercenaries and spies meet within its many private chambers. The Black Network disguises its ownership of the inn to avoid unwanted attention. The organization also has a vested interest in maintaining the prosperity of Yartar.
