The man behind the scenes during the partys first leg of the campaign. Was waiting for them in Wave Echo Cave, and offered them a job to fetch him an item he has been looking for in the caves. When the party refused due to his unwillingness to reveal what he needed the item for, he became hostile and prepared for an attack.
After a fierce battle, Nezznar managed to take down most of the party, and killed Granny, but was finally taken down by Demetrius after he taunted his mother. Nezznars body was left where it fell, with necrotic energy emanating from it, even in death.
The party later learned that he had been resurrected through unknown means, but in the process had become a vessel of Vuthul, and almost caught the party in the Ruins of Equinfjord.
After trekking through the Bloodwoods in search of Stormseeker, they found Nezznar waiting for them as they exited Maravin's Grave. He revealed that he had murdered Demetrius, and wanted his staff back, but the party were unwilling to part with it. A battle ensued, during which Nezznar seemed to absorb the magic from several of the party members items, and he tried to reclaim the staff from a fallen Relic, but the staff rejected him, wounding him gravely in the process. Unfortunately, he teleported away before they managed to finish him off.
After Arin was killed and replaced by Vhalak, the doppelganger was revealed for what they were, and under interrogation revealed that Nezznar has a safe haven on the east coast of the Akstan Kingdom. If the party wishes to finish off Nezznar for good, they will have to corner him in his own lair. The party attempted to do this, but the spider had already laid other plans, conquering and holding Ravenforge until his fathers demise, when the drow forces of Vuthul were finally struck down.
Nezznar supposedly met his final death shortly after the sundering, when his father, Vuthul, was killed. Around 75 years later, a cult is seemingly trying to bring him back somehow.
