The Night Queen, ruler over the minor plane of night. She heads the coven of witches now as Night Hags. Her hags travel the planes collecting souls for their queen and in return, their queen bestows power, youth and beauty to the chosen. 

Her followers are the deal makers, they can be found all over plestoria and offer to fulfill the dreams of the beaten and broken people in exchange for the souls.

Within the plane of night, the great tree holds the vessels in which the souls are captured, large purple crystals. The Night Queen can call on these souls to allow her followers power and eternal youth. Upon receiving the mark of the night queen the follower becomes part of the coven. That allows them safe passage through the night plane and also gains them allies and   safe havens around plestoria.
