Black Spider

The Black Spider is a mysterious figure that is searching for Wave Echo Cave. All we know is that they are a Drow and they struck some sort of deal with the Craigmaw for the clan's allegiance. They apparently sign their letters with the symbol of a Black Spider.

We know that The Black Spider was in contact with an Eye of Gruumsh in Thundertree. He had an emerald necklace that acted as a scrying stone. The Eye of Gruumsh was trying to rid Thundertree of Venomfang. The Necklace was lost in our heroes encounter with the dragon.
