Sosdrielle Vandree was a drow and the mistress of Gromph Baenre in Menzoberranzan. She bore Liriel Baenre and raised her for the first five years of her life. Although Sosdrielle was beautiful, she lacked ambition and magical talent, so she was not successful. She was ordered to death by Gromph when Liriel was five, so that Gromph could then claim Liriel, who showed wizardly aptitude, as his own. Drow children were considered the property of the mother, and had Sosdrielle not been killed, Gromph would have had no claim on the child.
