Tamoko

Tamoko was Sarevok's lover but did not wish for him to ascend to godhood and therefore Cythandria became his lover instead.

Tamoko first appears in the area just east of Candlekeep with Sarevok and two Ogres ambushing Gorion and his Ward. Tamoko casts a flame arrow at the player during the battle, causing Gorion to tell his ward to get out of the battlefield.

She next appears in Chapter 7 in Eastern Baldur's Gate outside the Sorcerous Sundries. Because of Sarevok abandoning her, Tamoko wants the player to dispose of Cythandria and stop Sarevok from becoming the new lord of murder.

After getting through the Thief's Maze, the player will find Tamoko again in the Undercity. She feels compelled to right the wrongs she has done against Sarevok by killing you. You can persuade her not to attack by saying the right things though.
