The Gathering of Power
The Zhentarim (or ‘Black Network’ as they are also known) are an Evil mercenary company who, over their centuries of existence, have experienced several leaps and bounds in terms of successes, but also several major defeats. They are a shadow of their former glory, but still an organization of great power and influence.
The adventurers have learned from Victain Ablath’s journal that The Zhentarim seem to be hatching a plot to harvest magical residuum which will apparently allow them to move on The Broken (whoever or whatever that is)
The party have now encountered and vanquished Lord Lareen one of the Vampire Lords of of the Zhentarim
