Order of the Hidden Moon
From Ditjes&Datjes
According to their myths the all-drow Order of the Hidden Moon was founded by the goddess Sariel when she came to The Underdark from The Fae Wild where she had founded The Sisterhood of the Hiding Sun. They have their own version of The Truth, given to them by Sariel herself and transmitted orally from Sister to Sister as it was never to be written down.
Before Althaea Taint Slayer took control over the order by slaying the abbess Erelda Xarann in Sariel's name, it had fallen prey to corruption, greed and local politics under the diabolical influence of the Archdevil Dispater.
