Cythandria is a female mage who replaced Tamoko as Sarevok's lover, though Cythandria only really wanted Sarevok so she could gain power and wealth.

In Baldur's Gate, she is seen for the only time in Chapter 7 at the top of the Iron Throne building. She will hail you on sight and question why you are here. No matter what you say, Cythandria will attack and summon two strong ogres called Arghh and Ughh. When she is dead you need to collect Sarevok's diary off her, as you will need it later.
