Yiccardaria is one of many handmaidens of Lloth. This type of creature is principally a mediate, a messenger between the priestesses of Menzoberranzan (more commonly Matron Mothers) and Lloth. In this case, Yiccardaria seems to be appointed to the reborn Yvonnel the Eternal because she is now the Chosen of Lloth. Yiccardaria monitors, protects and serves as emissary for Yvonnel. Short, Yiccardaria acts as a direct line with the goddess Lloth.
