Nezznar

Nezznar, also known as the "Black Spider", was a drow who was in search of the Forge of Spells in Wave Echo Cave.

The drow promised a share to Iarno Albrek in exchange for his loyalty and aid. Nezznar was the true leader of the Redbrands, controlling them (as well as a tribe of goblins and bugbears called the Cragmaws) in the hopes of finding Wave Echo Cave and unlocking its secrets (while also keeping it a secret for himself). Nezznar had many spies reaching all the way to Neverwinter.
