Cydaea is a villain from the video game Diablo III. She was the lover of Azmodan as well as one the Lord of Sin's lieutenants. She gained the title of Maiden of Lust and had command over her own band of Succubi who she treated much like her own daughters.
Cydaea was obviously held in great regard by Azmodan as the Lord of Sin's lieutenant. When the heroes arrived to stop Azmodan's invasion of Bastion's Keep the Lord of Sin had Cydaea protect the Heart of Sin, the power-source of his army. Cydaea gathers up the spiderlings until she gets back down.
Unfortunately for Azmodan his consort failed in her task and was slain while trying to defend the artifact.
