Pleione

The Mother of the sisters and the Oceanid nymph who birthed the stars themselves. She is the one perpetually chased by Orion, representing the "Eternal Flight" and the preservation of the lineage. She is the ocean-spirit of the sky, the celestial water that feeds the light of her daughters. She represents the source of the cluster, the foundational maternal force that endures the long hunt of time without ever being caught.
