City of Splendors: Waterdeep
Werespider member of the Scarred Beasts, revealed to be a double agent working for Darkwhispers
Eclavdra is one of the Scarred Beasts elders. She was tracked back to Skullport where it was revealed that she was working undercover for the mysterious criminal Darkwhispers and used as a mean to control the madman that is the Grey Beast.
She accepted to help the investigators in reaching Waterdeep rapidly because the Scarred Beasts' Alpha had become a liability for her master.
Eclavdra clearly had drow blood even though she is fully human and she can found at Nightshade's, a poison shop owned by an old woman rumored to follow Shar.
