Vezzeria

Vezzaria is a succubus from the The Abyss who seems to have an interest in the material plane.

Primrose Campaign

The party first meets Vezzeria in the ruined fort outside Yornletz while helping Lydia Pureheart track down abyssal threats. As the party arrives, she belittles them before leaving via a portal; leaving her minions to do her dirty work. Sandro finds a amulet on the body of her lacky, and decided to put it on. Later, Sandro hears a voice saying "this will be fun. 
Later on the party get helps from a red haired lady to carry out their ruse while trying to apprehend someone in Vexlorn. This woman hints at her true orgin by leaving the hint of ash and sulpher after evaporating into a black goo. 
While heading to the Glucksmort Ruins, the party is stopped by a young woman requesting aid in tracking down bandits. These bandits turned out to be an Incubus and other abyssal followers. Vezzeria appears at the end of the fight to finish off the Incubus. She refuses to remove the necklace from Sandro as "she still has use of him".
