The Knight of the Torrent

Lady Quirelle Moridhel corrupted the dread wraith that was borne from Kyran Meirion's execution in the Hall of Flies into a creature more fitting the name Knight of the Torrent, an arch-minion of Dagon that she planned to place on the Nine. The Dawn's Herald ultimately freed the Knight of the Torrent from Dagon's control during their return to the Hall of Flies.
