The Lost Pleiad

The sisters were transformed into stars by Zeus in order to save them from the unwanted attentions of Orion. However, one of the Pleiades eventually faded away, leaving six visible. In some myths, Electra fades away out of grief after Troy is destroyed and her descendants are killed, however other myths have Merope fade away, ashamed of her relationship with Sisyphus while her sisters had the attentions of gods.
