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 and still holds a loose alliance with her daughter's cell in Sembia. Originally, this was just to gain more power in the Western Heartlands but eventually she took over leadership of the cell.

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".

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.
