Shhuusshuru

Shhuusshuru, also known as Shadow Wing, gave birth to now-leader of the Cult of the Dragon, Aurgloroasa, before expelling her daughter from her realm after two centuries. She preceded the Sibilant Shade's ascension to dracolichdom with the help of a nascent cult cell in Berdusk. Originally, this was just to gain more power in the Western Heartlands but eventually she took over leadership of the cell. She still holds a loose alliance with her daughter's cell in Sembia

It was at her insistence that the Berduskan cell's second attempt at creating a Sacred One was to involve the red dragon Greshrukk "Red Eye". This plan involved luring a party of adventurers to Greshrukk's cave with a +4 defending longsword that contained the dragon's essence whom they would then ambush, steal the sword and perform the ritual.

From her lair in the tallest of the Far Hills she plots to take over Darkhold and from there, conquer the entire Chionthar river valley.
