Eberron: Unsung Heroes
An Erinyes bound to one of the deepest chambers of the Manor of Mirrored Sky. She was bound there centuries ago by Savrik Laisha, whose studies drew him down fell corridors. She has since developed a connection to the Laisha family, able to experience the world through their thirsts and lusts. Her connection had been waning until she gifted Celeste the power to save her future husband, and levied an unspoken price, changing Dantares’ and Celeste’s firstborn child in the womb from male to female, forming Kerra in her image and establishing with her a deeper connection than usual. She also ensured that Celeste would only give birth to females, in hoping that the end of the Laisha line would provide her freedom.
