This is the heart of Gulnan, a humanoid snake-like Yuan-Yi. Gulnan was one of the Waterdhavian creatures brought to Neverwinter to be part of the magical attempt to end the Wailing Death. She used the confusion of an unexpected attack to escape and cause untold horror in the Beggar's Nest. Aribeth awaits the delivery of this foul remnant, in the hopes that it may yet help provide a cure.
