Nresha al-Suriha, High Priestess of the Goddess Anshu.

The high priestess of the dark goddess Anshu, The Mother of Lies. Nresha is as influential, if not more so, than the Hssaar Pharaoh himself. She is an ancient, wizened creature but her frail physical appearance is in contrast to her wickedly sharp mind and the terrible magical power she can wield straight from her goddess.

One of the duties of the priesthood was to train and keep the hssaar Assassins - the greatest strength of the kingdom beyond its borders and feared throughout the lands. The high assassin was the most cherished of these by the priesthood and was brought up and trained in the ways of death by Nresha herself. However, the last to hold this title was a lizardman half-breed who would have been killed at birth were it not for his bright blue scales which were considered a sign of future greatness. Darkclaw was Nresha's pupil and had the honour of being her occasional consort. As such it was her liability when he abandoned his role and fled the kingdom, chosing instead to serve the dragon Bloodbane in return for the promise of longevity. Anshu was greatly displeased by Nresha's failure to hold sway over this assassin in whom so much had been invested and this time she took away Nresha's eternal youth, leaving her all but a withered husk of immortal old age.
